How to get the data heat pump (AE160JNYDGH)

[Mocky158]

Hello
I apologize in advance, I'm using Github for the first time for a question, so I don't know if this is the right way to write for advice.

I created esp according to see attachment. I also attached the settings I have to the file.

The problem is that I don't know how to know that something has been read or how to change it to read other data.

This is a heat pump (AE160JNYDGH)

I'm sorry if I wrote it incomprehensible, I'm using Google translator, I'm from the Czech Republic

Everything is fine fine.

logger:
level: DEBUG

Just try to change your yaml file like this:

uart:
  tx_pin: TX
  rx_pin: RX
  baud_rate: 9600
  parity: EVEN
  debug:
    direction: BOTH
    dummy_receiver: true
    after:
      timeout: 200ms
    sequence:
      - lambda: UARTDebug::log_hex(direction, bytes, ' ');

This should dumpy data witch is received into the log. This way you can see if there is any data.

There wireing looks fine so far. But please check you cable connections. I had a lot problems with wires that where not really connected when I started planing with it.

[Mocky158]

I've already checked the cables twice, but I can do it again, but I'm not physically at the heat pump at the moment.
It looks the same on the website after the code change.

What do you mean by "I'm not physically at the heat pump"?

[Mocky158]

I'm currently at work :D

[Mocky158]

I checked the wiring and it was fine, so I ended up swapping the rx/tx connectors, even though I had them connected correctly according to the picture. Finally, I started to see these data, I don't know if it's good.

[Mocky158]

So should I look for an address starting with 20? according to what is written in the note? Or what should I do with specific data?

[lanwin]

Can you please switch the uart baud rate to 2400 and try again.

[Mocky158]

I am sending the log here
logs_tepelne-cerpadlo_run.txt

[Mocky158]

I saw that these errors pop up when I turn it on, is it OK?

[lanwin]

Hmm. Can you please swap F1 and F2 again and try with 2400 and 9600 baud. On my system I got also data with F1 and F2 swapped. But the data is not valid. Your log looks like that.

You can ignore the error for now.

[Mocky158]

I'll get to the heat pump again tomorrow morning. So what should I test for RS485 speeds? 2400 and 9600? and I will try to transfer F1 to F2.

[lanwin]

Just try both and see if you can get anything under "Discovered devices"

[Mocky158]

I tried different combinations and got no result. I will try to order the M5Stack to rule out my device's fault.

EDIT:
So, on my last attempt, this popped up, is this a change?

[Mocky158]

Today I ran out of the purchased M5STACK ATOM Lite which is listed in Plug and Play. I would like to ask to which connectors I should connect F1 and F2. They are pins 19 and 22 as in the M5STACK ATOM RS-485

EDIT:
Now I realized that both components are needed :D that's right :D

[bzumik1]

Yes, both are needed (M5STACK ATOM Lite and M5STACK ATOM RS-485)🙂

[Mocky158]

Could I ask for a sample of what I should see in the log? If I should also see the device (number) in the line Discovered devices:
?

Or a sample of the log that is newsworthy.

[lanwin]

Sorry I overlooked your edit. #23 (comment)

That is exactly what we want to see. Your Indoor unit is 20.00.00. When you see that it works and you can control your devices when add a configuration for each unit to your yaml.

[Mocky158]

You don't need to apologize for clarifying, it's still bothering me
I removed:
debugging:
direction: BOTH
dummy_receiver: true
after:
timeout: 200ms
sequences:
- lambda: UARTDebug::log_hex(direction, bytes, ' ');

After that they started showing me temperatures etc. :-) I'm glad it works.
I am sending the data that I currently see.
I would like to ask, I am doing all this because I want when there is a surplus of energy from PV so that the utility water starts to heat up more, so I want it to be heated to 42C and I would like to raise the condition to 60C via the automation in NodeRed every time there is a battery etc. as an example.

But at the moment I can't see these data, how should I proceed to add them?

EDIT:
sometimes this message pops up

[lanwin]

Well the problem here is that we need to know witch data point is responsible for controlling the water heating data. I am not sure yet how we get there.

[bzumik1]

@lanwin wouldn't the advanced logging, you are working on, help here? We should see the data published on the bus.

[Mocky158]

Can I offer a remote connection to my ESP .Would that help to develop faster.

[lanwin]

The log data is pretty confusing since its a lot.

I currently thinking about generating something like a table where every variable can appear with its last value. But I am not sure if that is possible with ESPHome.

[lanwin]

Thank you. Maybe later. For now that would not help.

[Mocky158]

So let me know as soon as I can help you with anything related to reading the data.For now I'll wait :-)

I got these PDFs from Samsung support that show the registry numbers and what's under them. I don't know if it could help to identify which value should be changed to change the temperature of the service water.

Sorry I overlooked your answer. Sadly this did not help. The numbers really only count when you have that Modbus Interface.

[Mocky158]

Good day
I would like to ask if there is any progress in the decoding of entities for the heat pump.
Thank you for answer.

Hi @sonics007 let's keep the conversation in English so it is clear to all others who come here to GitHub
