Hello,
I'm using fauxmoESP to control my thermostat, it recently broke down, and the maintenance guy never returned back so I had to make something out of it.
So you can probably guess the rest.
But I'm wondering couple of things;

1. I wasn't expecting much power draw so I bought a cheap power bank (2600mah, 5V 1A) but its only powers the circuits maybe a day or less. So is there a way to save some energy or what kind of battery might be good? My thermostat has only two cables so no C cable that I can draw power from.

2. 2 days ago it's stopped working, I tried re-uploading code, etc, nothing worked. Alexa says there is no such device, but I can see it in the device list, so I removed devices and tried to re-discover but, this time it is not been found at all.
   So maybe Alexa does not recognize it anymore, is the same situation for you too?

3. Is there any other way to trigger it other than alexa?

4. Also Hue iOS app can not discover the device I assume this is expected right?

A couple options for saving power would be to have the device go into deep sleep, however to have it work reliably that is likely not a great solution (ie: you wouldn't be able to reach it when it's sleeping). One little thing that you might do is revome the power LED if it has one... they use a surprising amount of your power.

2 days ago it's stopped working, I tried re-uploading code, etc, nothing worked. Alexa says there is no such device, but I can see it in the device list, so I removed devices and tried to re-discover but, this time it is not been found at all.
So maybe Alexa does not recognize it anymore, is the same situation for you too?

Make sure you're using version 3.2.2. Also, if you're using an ESP8266, make sure to select "lwIP v1.4 High Bandwidth". Some people have recently had issues with v2.

Is there any other way to trigger it other than alexa?

For one of my projects I used Bluetooth SPP (serial) with a crude app on my phone (I have it send JSON data to control lights).

You can find code for that here: https://github.com/pvint/Starfish-idf/blob/master/main/starfish_main.cpp but... I'll warn you - that code is a mess!

Also Hue iOS app can not discover the device I assume this is expected right?

I honestly don't know. It has been working on Android recently, but I don't have any iOS products to test with.

[PauloFDO]

Hey! First of all thanks for this library, it works great, I have been using it for a couple of weeks now and it does what you would expect from it, but I have been wondering about one thing and googling is getting me even more confuse, what do people use when they want to create an commercial Alexa compatible device? Is Arduino a real option or there is another alternative? Fauxmo is (I assume) a free option for DIY devices, I know that Arduino has an Arduino IOT, but that is also for hobbyists for what I can understand (you need to download an Arduino skill in Alexa for it to work) plus you either pay monthly to use third party Arduino devices or buy the official ones, Amazon ACK feels like the way to go but that feels very complicate, you need to buy an amazon exclusive kit and is definitely not cheap if you need to pay for each device where you want to implement it, how do products manage to be amazon and google assistant friendly if they need to buy separate things for each?

[PauloFDO]

ye, I have been looking into it and everything looks pretty annoying, I wish they could sort it out like this app, just put something in your code and you are ready to go

[pvint]

I've looked into this a bit in the past too, and yeah, it's not exactly simple. I think the way to go is to develop your own Alexa "skill" to support your device(s). It's been a couple years since I investigated developing Alexa Skills, and I don't really remember well what's involved anymore. I do recall that it looked like a pain in the ass. lol

[PauloFDO]

I will probably get into it whenever I have time for learning purposes and will let you guys know the step by step

[PauloFDO]

I looked into this for hours, all the solutions include having to communicate with Amazon servers (of course they want their cut) in one way or the other, but there is many ways to do so, I didn't implement it yet but I believe that the easiest one is create an Amazon skill that acts as a web server, ESP will be connected to it listening and when the user gives a voice command it executes whatever action you need.

For DIY projects don't even look into it, stick to this library, 1000% easier to use than connect anything in the official way

[gabrielgvicente]

Hi PauloFDO, were you able to deploy your private application? I'm going through the same difficulties. Would you help me?

[paulrjacques]

This library works great! I was using sinric but this is much easier to use. Using this library, I was wondering if any one was working on a way to return data to Alexa. I am building a drip control system for my ranch and I'd like to ask Alexa what valves are on or what the water pressure is.

[PauloFDO]

as far as I know this library basically tricks Alexa into thinking that it is talking with phillips hue lights, so it is a one way communication (the lights never talk back)

[siniradam]

Actually, it (sort of) talks back. If not how could you know if the light is on or off?

[PauloFDO]

my guess is that if you say "turn the lights on" it tries to turn it on even if they are already on, which will change nothing, same for turning off, it doesn't need to check the current state at all

[romoloman]

Fauxmo taks back with alexa, the setState method can notify alexa if the device is on or off...

[habu2]

We have fauxmo-esp forwarding messages from alexa to a computer on a different network (unnecessarily complicated setup, long story...), and we encountered the problem that the scripts would only trigger once. I didn't fully trouble shoot it, so this could be an incorrect assumption, but I think it was due to alexa not sending a repeat "on" signal to a device that's already "on." So we changed the alexa routines to send both and on and off command with a short gap in between, and that fixed the problem.

[paulrjacques]

I'm hopeing someone will add to the library. With Sinric, you can pass requested data back.Thanks...Sent from my Verizon, Samsung Galaxy smartphone -------- Original message --------From: Paulo De Oliveira <[email protected]> Date: 1/29/21 1:29 PM (GMT-08:00) To: vintlabs/fauxmoESP <[email protected]> Cc: paulrjacques <[email protected]>, Comment <[email protected]> Subject: Re: [vintlabs/fauxmoESP] Welcome to fauxmoESP Discussions!

[pvint]

Never heard of Sinric. I'll have to look into that sometime. I would love to find a way to pass data back too.

[barneyz]

Sinric is a cloud solution with a custom Alexa skill and a sinric server in india and you need an account. So it functionally can make "everything" like reading sensors, but when the sinric-server is offline(maybe forever), all sinric devices stop working.
Fauxmoesp and espalexa uses the Alexa-build-in Philips Hue solution with no other dependencies than the Alexa speech recognition on Amazon-servers, but only with the provided functions.

[picstart]

if (digitalRead(LED)) fauxmo.setState(ID_LED, true, 255);else fauxmo.setState(ID_LED, false, 255);
error: call of overloaded 'setState(const char [11], bool, int)' is ambiguous
The above overloading has issues when compiling

[pvint]

Is that from a released version or from git?

[CooperBoy]

Good Morning Paul and all,
I have just started to get back to trying to program and have decided to jump into the deep end by trying to code a voice-activated, via my existing Alexa kit to control my blinds, garage door, +++.

I have remote-controlled blinds in my kitchen and would like to make them move by saying to Alexa "blinds up/down" and also to open/close my garage...

I have stumbled upon your code that I believe could be modified to work, problem is I cannot find the information I need to use the FauxmoESP.h Class. To construct an object of the Class I need to pass it data to and receive return data from (I'm assuming now), but can not find any info on this page regarding the Class functions.

I'm sorry if this is a stupid question and that I'm really not understanding OOP and perhaps you could put me right, but I can't see how one is to use the Class if one can not see what is needed, from inside, to use it.

I might not be seeing the wood for the trees, if so then could you point me to where I can find all the Class info.

Regards, from a 70-year-old who is quite pleased he has found something to do.

My history; I have programmed in Assembla many years back and have bashed out a few C++ (Arduino) scrips including Temperature sensors, with an ESP8266 with OLED display showing the Temperature (How to show the little circle degree sign as it's not in the standard ASCII code - I managed to figure this out, change font ++) of my freezer that was playing up. I used a 25Amp SSR to turn the freezer pump motor on/off and it's all working. Now I need to handle the no frost problem - what temp does it have to get up to stop the frost then back on again?

Hi Bob, have you checked out the examples? https://github.com/vintlabs/fauxmoESP/blob/3e622227660011c3ed7d6468319ac38f6778e669/examples/fauxmoESP_Basic/fauxmoESP_Basic.ino

[paulrjacques]

Fauxmoesp is in github, Google fauxmoesp. I am working on a drip watering system controller which is heavy with relay control and analog input (water pressure measurements) and an LCD (serial)display in the control box. I put all the code on an arduino and call an esp for wireless access. Besides not wanting to deal with 3.3v drivers, the esp lacks the analog inputs, serial ports and discrete control I need. I wish there was away of using fauxmo on an Arduino, that would solve all my problems. Currently I am generating a web page but i would like to use Alexa.PsulSent from my Verizon, Samsung Galaxy smartphone -------- Original message --------From: CooperBoy <[email protected]> Date: 2/19/21 7:03 PM (GMT-08:00) To: vintlabs/fauxmoESP <[email protected]> Cc: paulrjacques <[email protected]>, Comment <[email protected]> Subject: Re: [vintlabs/fauxmoESP] Welcome to fauxmoESP Discussions!

Hi Paul, We've been trying to find an ESP library that will support sending data back to Alexa. In my case I'm trying to find an Arduino library to do it. Paul

[pkriens]

Does anybody have success with multiple ESP's? I can make Alexa recognize one switch (and this requires some twiddling) but I've never been able to get her to pair with more than one. Is this a limit of Alexa (I am using a dot)

[patoberli]

Check if the devices happen to have the same MAC address, could happen with cheap clones. The uniqueid is generated with the MAC, although that 00:00 looks weird (no C++ programmer here):
` // create the uniqueid
String mac = WiFi.macAddress();

snprintf(device.uniqueid, 27, "%s:%s-%02X", mac.c_str(), "00:00", device_id);

// Attach
_devices.push_back(device);

DEBUG_MSG_FAUXMO("[FAUXMO] Device '%s' added as #%d\n", device_name, device_id);

return device_id;`

I've since switched to the WLED project though for the newer projects (I have one left with Fauxmo).

[MichaelB4711]

I have done that. I use the library on two ESP8266 for several devices.
In fact if i move a device from one esp to another i have to delete the existing in alexa and rediscover it.
It runs without problem.

[MichaelB4711]

I use this library to control a few lights, a heater regulator with adjustable temperature and latest to operate the reomte control of a tv.
to set different temperature levels or to press different buttons on the tv remote i use the different brightness levels of the virtual lamp which is presented to alexa. the library runs on ESP8266 in my setup.
since the virtual lamp in alexa has also the possibility to adjust color settings and not only the brightness level i wondered if the support for color could be implemented in the library. with a look in the source code in my opinion it would be easy. but the interface of the callback function is not made to handle a second parameter. it would be required to change the callback interface or to implement a second callback function.
so my question is what would be the best way to do the necessary changes, to keep compatibility and to share the result after with the community?

[Rumbaar]

Hello,

Thanks for maintaining this library, and I'm hoping it'll meet my needs. Will I be able to 'trick' Alexa using this to think it's operating a Roller Shutter. As I want to have the commands OPEN/CLOSE or STOP instead of Turn ON/OFF the device. Example "Alexa Open Kitchen Shutters" or "Alexa Kitchen Shutters Open", but the first command is preferred.

Also will I be able to perform combined faux functions like 'Favorite' command which is effectively pushing STOP+DOWN on the OEM controller. I'm going to be using a ESP that'll use transistors to trigger the 'dumb' manual buttons on the controller.

So can I make up the commands Alexa will respond to in a better context/grammatical way? Also I like the percent option, and have thoughts about having that function set a timer till issuing the STOP command. Example "Alexa Open Kitchen Shutters to 50%" and have it trigger the CLOSE command (Shut it fully), then OPEN and timer for x second before STOP which will be about where it's 50%.

[MichaelB4711]

Hi Rumbaar,

if you do something like alexa, shutters 50 you receive a callback in fauxmo with the value of 127 or 128. you might install a debug to put the exact value to the debug console.
after you have received that in the esp of course you can send a command to the shutters to operate and after a particular amount of time to send a stop signal to the shutter.
but of course you don't know the current position of the sutter. so you don't know if you have actually to open or to close them.
for that perhaps you could try to use two commands like "shutters 30" to put them down to 50 and "shutters 60" to put them up to 50. depending what you need you could add more then two possibilities.
alexa allows you to add routines to a device with different keywords. with a routine you send a particular brightness level and handle the action in the esp. for example i have implemented "TV left" which in fact sends a brightness level of 25 and inside the esp it sends "input menu" and "cursor left" one second later to the tv with an infrared sender. so the tv goes in the input channel menu and select the hdmi input channel 1 position left of the current channel. with "TV right" i do the opposite direction with a temperature value of 30.

[Rumbaar]

Hi Michael,

Thank you for your response. Yes, currently the OEM favorites command has the device close the shutters and then move to the pre-programmed position. So was going to emulate this process via a timed DOWN (let it close, wait x), then OPEN and STOP after x seconds.

I'll be having upwards of 12 devices I'm hoping to modify and operate as independent entities, but hopefully I can group them into groups too (bedrooms, upstairs, downstairs, etc)

[ScaredyCat]

For OPEN/CLOSE/STOP just create a routine that sends an on/off/brightness command to your device eg

Say "Alexa OPEN shutters" -> routine -> turn shutter on - Code == enable open-shutter-relay
Say "Alexa CLOSE shutters" -> routine -> turn shutter off - Code == enable close-shutter-relay
Say "Alexa STOP shutters" -> routine -> set shutter brightness 50% - Code == if brightness == 50 stop shutter-relays

[Acc3ssD3n13d]

Hello,
I'm using fauxmo to control my 3d printer. The goal right now is just to turn it off and on. Later down the road I'd like Alexa to read off percentages, preheat the printer, etc.

[fernandobelissimo-60]

Good morning friends! I am using this great library to control some relays with the WiFiManager to connect to web. I need to use brightness control in some resistives loads. I would liked documentations of this library for a better use. Thanks for all!!

como integraste wifimanager y fauxmo en el mismo sketch?
por que si uso wifimanager alexa no encuentra el dispositivo

[fernandobelissimo-60]

Boa tarde amigo, Uma pergunta, prefere que eu escreva em portugues ou inglês?? Realizei algumas pequenas modificações na biblioteca wifimanager e consegui controlar até 10 dispositivos utilizando o Accesspoint do ESP32 (ou 8266), selecionando ssid e senha... Caso interesse, posso te enviar o código e o hardware que tive de implementar. Atualmente estou desenvolvendo o projeto para Alexa utilizando um módulo ACK... faço login na rede wifi utilizando somente um QRcode. Voltando ao projeto com o ESP32, acrescentei ao sistema uma maneira de "limpar " todos SSID´s e senhas registradas, pois sempre que um novo acesso é imposto meu circuito armazena essas informações... Um abraço, Fernando Belíssimo OBS>: resposta para ***@***.*** Em qui., 28 de out. de 2021 às 16:28, legnalegna1 ***@***.***> escreveu:

I removed fauxmo.handle(); from the loop but the device still responds to Alexa commands. How is this happening?

[ray-leiter]

If you want to convince yourself of the need for the handle() method, do this:

1. using the Alexa app on your phone, remove the device
2. comment out the statement (handle() method call)
3. upload the modified code (handle() method commented out)
4. Ask Alexa to discover devices

Now you will not discover the device you previously removed.

[riban-bw]

Indded - so the handle() function is only to handle discovery and not for anything else, i.e. it is fine to only call handle() (repeatedly) when in discovery mode? I have implemented such a mechanism and it avoids the device crashing every few days. I just need to perform some button press combination to toggle enable mode.

[hjahend]

Hi all, I use Tasmota based and other devices for my home automation for many years already.
Wondering if fauxmoESP could send and receive (relay function) MQTT, WEMO /HUE messages via a serial port on my home automation controller.
Questions:
Is it at all possible?
What message format as inputs to fauxmoESP? Same for outputs (messages back)?
Do I have to alter the fauxmoESP software (if so what and how)?
How to bind it all together in software and check it??

[Ikarius81]

hello , i have a problem since a few days . Im using fauxmoesp on a esp32 controller.
My Alexa can discover my new Devices (Lamps) but Alexa is not able to switch them on or off anymore. Alexa is just saying that the Device is not reacting.
Anyone got an idea , what i could do in this case to fix the problem?

KindRegards ^^

[Ikarius81]

sure ^^ it was working well for like 1 month , and now it doesnt , ive been reading on some sites to use callbackstate instead of onsetstate to return a proper value to the alexa.

hi friend
Callbacks it's much more stable... I'll review your code, but think about using the project that's in the following link:

https://github.com/MasTerYoDa-60/alexa-esp32

try, and i help you if you need

[Ikarius81]

hi , ok i will give it a try ^^ thx

[pvint]

@Ikarius81 That's quite a lot of stuff in the callback function. The callback function needs to be small and fast or unexpected things can happen.

Instead of doing all the heavy lifting in there, it might be good to just set a global flag and a couple variables that you can poll in your loop() and handle the actual switching there.

[Ikarius81]

yeh ill take a look bit later , when i have time , right now im busy with the festivities ^^

Hello, Alexa does not recognise my ESP32. The ESP32 is connected to the same WIFI with my smartphone. Does it require an Amazon ECHO for searching?

Hi 1Alonzo,

i recommend to you to add three lines of code to fauxmoESP.h:

#define DEBUG_FAUXMO Serial
#define DEBUG_FAUXMO_VERBOSE_TCP true
#define DEBUG_FAUXMO_VERBOSE_UDP true

that should go below the line
#define FAUXMO_DEVICE_UNIQUE_ID_LENGTH 12

recompile to activate debug inside the library.
like that you can discover if there are some communications discovered by the library.
the are displayed in the serial messages window of arduino ide.

i get many messages if i start a search from my smartphone in the alexa app.
i also get many messages if i start a a search by an amazon alexa device.
i think you don't need an amazon alexa device.

currently i don't schedule to add a new fauxmo device to amazon alexa.
but i have yet several and the library handles them nice and smooth.
i use different esp8266 and even an esp01s to handle them.
but that should not make a difference to an esp32.

[Aterox-os]

Hello,
Im new to Fauxmo and home automation with it, and I'm wondering if and how its possible to have a command like Lamp1 50%.

[ormej01]

Hi,
A couple of quick questions:

1. Is it possible to set a hostname in Fauxmo? When I look at what is going on in my local network, it looks like the name is cobbled together using MAC address and some other random bits.
2. I have also experienced reliability problems when using Fauxmo devices with Alexa. Would a fixed IP address help? Is there a way to set a fixed IP in Fauxmo?
   Many thanks!

[nfsilva999]

Hello guys,
I'm very newbie in ESP32 and fauxmo so, thanks a lot for all the help.

My question is: Is there some way to expose a virtual device to alexa as a sensor?

The instruction AddDevice seems only expose as a light.

Thanks for the help!

Regreats from Portugal!

[SM0076895]

Hello!
I'm using fauxmo to control Lights. I'm connecting a switch, a LOLIN S2 mini (ESP32) and optocouplers to control the lamp.
I'm having trouble with the setState function. I read the state of the switch but the light is not turning on when entering to the setState function.
I hope I can receive some feedback on that. Here is my code:

#include <Arduino.h>
#include <WiFi.h>
#include <fauxmoESP.h>

const char* ssid = "_*personal info removed*_";
const char* pwd = "_*personal info removed*_";

fauxmoESP faux;
#define LED             15
#define ID_LED          "test led"

int SW = 16;

void wifiSetup(){
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid,pwd);
  while(WiFi.status() != WL_CONNECTED){
    Serial.println(".");
    delay(100);
  }
  Serial.println("Connected");
}

void setup(){
  Serial.begin(115200);
  pinMode(LED, OUTPUT);
  pinMode(SW, INPUT_PULLUP);
  digitalWrite(LED, LOW);
  wifiSetup();
  faux.createServer(true);
  faux.setPort(80);
  faux.enable(true);
  faux.addDevice(ID_LED);
  faux.onSetState([](unsigned char device_id, const char * device_name, bool state, unsigned char value){
    if(strcmp(device_name, ID_LED)==0){
      digitalWrite(LED, state ? HIGH : LOW);
    }
  });
}

void loop(){
faux.handle();
  static unsigned long last = millis();
  if(millis() - last > 5000){
    last = millis();
    ESP.getFreeHeap();
  }
  int a = digitalRead(SW);
  Serial.println(a);
  delay(100);
  if(a == 1 ){
    Serial.println("Turning on");
    faux.setState(ID_LED, true, 255);
  }
  else{
    Serial.println("Turned off");
  }
}

UPDATE: I am looking at the Alexa app, and it says that "Device doesn't support requested value", What am I missing here?

[Jamdog2477]

Hi, total noob here (sorry!).
I have a ESP8266-12F which i have flashed with the fauxmoESP_Basic code.
I am wondering where a wiring diagram would be so i can wire up the LEDs to the board?
Also is there a way to get Alexa to see these as "Switches" instead of "Lights"?
