A Home Assistant custom Integration for local handling of Tuya-based devices.

This custom integration updates device status via push updates instead of polling, so status updates are fast (even when manually operated).
This custom integration updates device status via pushing updates instead of polling, so status updates are fast (even when manually operated).
The integration also supports the Tuya IoT Cloud APIs, for the retrieval of info and of the local_keys of the devices.


**NOTE: The Cloud API account configuration is not mandatory (LocalTuya can work also without it) but is strongly suggested for easy retrieval (and auto-update after re-pairing a device) of local_keys. Cloud API calls are performed only at startup, and when a local_key update is needed.**


The following Tuya device types are currently supported:
* 1 and multiple gang switches
* Wi-Fi smart plugs (including those with additional USB plugs)
* Switches
* Lights
* Covers
* Fans
* Climates (soon)
* Climates
* Vacuums

Energy monitoring (voltage, current, watts, etc.) is supported for compatible devices.

> **Currently, only Tuya protocols 3.1 and 3.3 are supported (3.4 is not).**
This repository's development began as code from [@NameLessJedi](https://github.com/NameLessJedi), [@mileperhour](https://github.com/mileperhour) and [@TradeFace](https://github.com/TradeFace). Their code was then deeply refactored to provide proper integration with Home Assistant environment, adding config flow and other features. Refer to the "Thanks to" section below.


# Installation:

Copy the localtuya folder and all of its contents into your Home Assistant's custom_components folder. This folder is usually inside your `/config` folder. If you are running Hass.io, use SAMBA to copy the folder over. If you are running Home Assistant Supervised, the custom_components folder might be located at `/usr/share/hassio/homeassistant`. You may need to create the `custom_components` folder and then copy the localtuya folder and all of its contents into it
The easiest way, if you are using [HACS](https://hacs.xyz/), is to install LocalTuya through HACS.

Alternatively, you can install localtuya through [HACS](https://hacs.xyz/) by adding this repository.
For manual installation, copy the localtuya folder and all of its contents into your Home Assistant's custom_components folder. This folder is usually inside your `/config` folder. If you are running Hass.io, use SAMBA to copy the folder over. If you are running Home Assistant Supervised, the custom_components folder might be located at `/usr/share/hassio/homeassistant`. You may need to create the `custom_components` folder and then copy the localtuya folder and all of its contents into it.


# Usage:

**NOTE: You must have your Tuya device's Key and ID in order to use localtuya. There are several ways to obtain the localKey depending on your environment and the devices you own. A good place to start getting info is https://github.com/codetheweb/tuyapi/blob/master/docs/SETUP.md .**

**NOTE - Nov 2020: If you plan to integrate these devices on a network that has internet and blocking their internet access, you must also block DNS requests (to the local DNS server, e.g. 192.168.1.1). If you only block outbound internet, then the device will sit in a zombie state; it will refuse / not respond to any connections with the localkey. Therefore, you must first connect the devices with an active internet connection, grab each device localkey, and implement the block.**

**NOTE: starting from v4.0.0, configuration using YAML files is no longer supported. The integration can only be configured using the config flow.**


To start configuring the integration, just press the "+ADD INTEGRATION" button in the Settings - Integrations page, and select LocalTuya from the drop-down menu.
The Cloud API configuration page will appear, requesting to input your Tuya IoT Platform account credentials:

![cloud_setup](https://github.com/rospogrigio/localtuya-homeassistant/blob/master/img/9-cloud_setup.png)

To setup a Tuya IoT Platform account and setup a project in it, refer to the instructions for the official Tuya integration:
https://www.home-assistant.io/integrations/tuya/
The place to find the Client ID and Secret is described in this link (in the ["Get Authorization Key"](https://www.home-assistant.io/integrations/tuya/#get-authorization-key) paragraph), while the User ID can be found in the "Link Tuya App Account" subtab within the Cloud project:

![user_id.png](https://github.com/rospogrigio/localtuya-homeassistant/blob/master/img/8-user_id.png)

> **Note: as stated in the above link, if you already have an account and an IoT project, make sure that it was created after May 25, 2021 (due to changes introduced in the cloud for Tuya 2.0). Otherwise, you need to create a new project. See the following screenshot for where to check your project creation date:**
![project_date](https://github.com/rospogrigio/localtuya-homeassistant/blob/master/img/6-project_date.png)

After pressing the Submit button, the first setup is complete and the Integration will be added.

Note that a single device can contain several different entities. Some examples:
- a cover device might have 1 (or many) cover entities, plus a switch to control backlight
- a multi-gang switch will contain several switch entities, one for each gang controlled
> **Note: it is not mandatory to input the Cloud API credentials: you can choose to tick the "Do not configure a Cloud API account" button, and the Integration will be added anyway.**
Restart Home Assistant when finished editing.
After the Integration has been set up, devices can be added and configured pressing the Configure button in the Integrations page:

# Option two: Using config flow
![integration_configure](https://github.com/rospogrigio/localtuya-homeassistant/blob/master/img/10-integration_configure.png)

Start by going to Configuration - Integration and pressing the "+" button to create a new Integration, then select LocalTuya in the drop-down menu.
Wait for 6 seconds for the scanning of the devices in your LAN. Then, a drop-down menu will appear containing the list of detected devices: you can
select one of these, or manually input all the parameters.

# Integration Configuration menu

The configuration menu is the following:

![config_menu](https://github.com/rospogrigio/localtuya-homeassistant/blob/master/img/11-config_menu.png)

From this menu, you can select the "Reconfigure Cloud API account" to edit your Tuya Cloud credentials and settings, in case they have changed or if the integration was migrated from v.3.x.x versions.

You can then proceed Adding or Editing your Tuya devices.

# Adding/editing a device

If you select to "Add or Edit a device", a drop-down menu will appear containing the list of detected devices (using auto-discovery if adding was selected, or the list of already configured devices if editing was selected): you can select one of these, or manually input all the parameters selecting the "..." option.

> **Note: The tuya app on your device must be closed for the following steps to work reliably.**

![discovery](https://github.com/rospogrigio/localtuya-homeassistant/blob/master/img/1-discovery.png)

If you have selected one entry, you only need to input the device's Friendly Name and the localKey.
If you have selected one entry, you only need to input the device's Friendly Name and localKey. These values will be automatically retrieved if you have configured your Cloud API account, otherwise you will need to input them manually.

Setting the scan interval is optional, only needed if energy/power values are not updating frequently enough by default. Values less than 10 seconds may cause stability issues.

# Migration from LocalTuya v.3.x.x

If you upgrade LocalTuya from v3.x.x or older, the config entry will automatically be migrated to the new setup. Everything should work as it did before the upgrade, apart from the fact that in the Integration tab you will see just one LocalTuya integration (showing the number of devices and entities configured) instead of several Integrations grouped within the LocalTuya Box. This will happen both if the old configuration was done using YAML files and with the config flow. Once migrated, you can just input your Tuya IoT account credentials to enable the support for the Cloud API (and benefit from the local_key retrieval and auto-update): see [Configuration menu](https://github.com/rospogrigio/localtuya#integration-configuration-menu).

If you had configured LocalTuya using YAML files, you can delete all its references from within the YAML files because they will no longer be considered so they might bring confusion (only the logger configuration part needs to be kept, of course, see [Debugging](https://github.com/rospogrigio/localtuya#debugging) ).


# Energy monitoring values

You can obtain Energy monitoring (voltage, current) in two different ways:

1) Creating individual sensors, each one with the desired name.
Note: Voltage and Consumption usually include the first decimal. You will need to scale the parament by 0.1 to get the correct values.
1) Access the voltage/current/current_consumption attributes of a switch, and define template sensors
2) Access the voltage/current/current_consumption attributes of a switch, and define template sensors
Note: these values are already divided by 10 for Voltage and Consumption
1) On some devices, you may find that the energy values are not updating frequently enough by default. If so, set the scan interval (see above) to an appropriate value. Settings below 10 seconds may cause stability issues, 30 seconds is recommended.
3) On some devices, you may find that the energy values are not updating frequently enough by default. If so, set the scan interval (see above) to an appropriate value. Settings below 10 seconds may cause stability issues, 30 seconds is recommended.
