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).
The following Tuya device types are currently supported:
- 1 and multiple gang switches
- Wi-Fi smart plugs (including those with additional USB plugs)
- Lights
- Covers
- Fans
- Climates (soon)
Energy monitoring (voltage, current, watts, etc.) is supported for compatible devices.
This repository's development began as code from @NameLessJedi, @mileperhour and @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.
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
Alternatively, you can install localtuya through HACS by adding this repository.
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.
Devices can be configured in two ways:
Add the proper entry to your configuration.yaml file. Several example configurations for different device types are provided below. Make sure to save when you are finished editing configuration.yaml.

- 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
Restart Home Assistant when finished editing.
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.
Note: The tuya app on your device must be closed for the following steps to work reliably.
If you have selected one entry, you only need to input the device's Friendly Name and the localKey.
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.
Once you press "Submit", the connection is tested to check that everything works.
Then, it's time to add the entities: this step will take place several times. First, select the entity type from the drop-down menu to set it up. After you have defined all the needed entities, leave the "Do not add more entities" checkbox checked: this will complete the procedure.
For each entity, the associated DP has to be selected. All the options requiring to select a DP will provide a drop-down menu showing all the available DPs found on the device (with their current status!!) for easy identification. Each entity type has different options to be configured. Here is an example for the "switch" entity:
Once you configure the entities, the procedure is complete. You can now associate the device with an Area in Home Assistant
You can obtain Energy monitoring (voltage, current) in two different ways:
- 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.
- 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
- 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.

Whenever you write a bug report, it helps tremendously if you include debug logs directly (otherwise we will just ask for them and it will take longer). So please enable debug logs like this and include them in your issue:
logger:
default: warning
logs:
custom_components.localtuya: debug- Do not declare anything as "tuya", such as by initiating a "switch.tuya". Using "tuya" launches Home Assistant's built-in, cloud-based Tuya integration in lieu of localtuya.

Create a (good and precise) sensor (counter) for Energy (kWh) -not just Power, but based on it-. Ideas: Use: https://www.home-assistant.io/components/integration/ and https://www.home-assistant.io/components/utility_meter/
