Tuya sensor subscription for Domoticz

tuya2domoticz

This package is intended to be used as a standalone application (command line or daemon) for receiving Pulsar asynchronous messages from TUYA sensor devices, and then passing those as alarm device messages to Domoticz using http requests.

This is NOT a Domoticz plugin!

For Domoticz, a tuya plugin is already implemented: https://github.com/Xenomes/Domoticz-TUYA-Plugin but it just handles switches and devices that are usually online, not battery operated sensors. For me, that was not useable. I have reflashed all my non-battery Tuya devices (wall sockets) with Tasmota, but for the actual sensors the reflashing is a painful and unguarranteed process. If reflashing is preferred, have a look at this: https://templates.blakadder.com/Y09.html

Currently, the only tested device is the Y09 WiFi water leakage sensor.

Home Assistant can also handle tuya devices through a tuya maintained plugin (tuya-home-assistant) but, for what I can tell, it just uses a polling mechanism with a big warning about the delay in use. The Domoticz-TUYA-Plugin apparently uses the same plugin to interface with Tuya.

Screenshots

The devices are "virtual devices" of type "alarm". I didn't find a suitable existing device to put everything in one place but this is effective (it's easy to script these to trigger some real alarm). Some pictures related to the current setup below:

Pre-requisites

1. Pair the Tuya devices using the default SmartHome Application.

2. Create an account and a cloud project on http://iot.tuya.com.

3. Link the SmartHome app linked devices in the project (Devices -> Add Device -> Add Device with IOT Device Management App).

4. Configure the Home and device related service APIs.

5. Write down the ID and KEY for that project. One device UID is also required, as the "normal" device listing fails.

Installation

Using pip:

# Install tuya2domoticz
pip3 install tuya2domoticz

Setup

1. Configure devices The first run will help to configure the device. You will need to set up the ACCESS_ID, ACCESS_KEY, one of the registered devices UID (as reported from the tuya IOT project setup), Domoticz IP:PORT and then the device numbers for the Domoticz virtual devices. For each pyhisical device, there should be one a virtual alert device for the actual status, and one for the battery status. If the device battery status is not needed, it shall be set to "-2". In the end, a "config.json" file will be created with the needed information. This file can be updated manually if needed.

$ python3 -m tuya2domoticz -r

2. Install the module as service:

$ python3 -m tuya2domoticz -i

Note, this will create a /home/$USER/tuya2domoticz folder (if not existing) and will copy the "config.json" file previously generated. Also, the tuya2domoticz.service file will be copied to /home/$USER/.config/systemd/user/. This systemctl service file can also be modified as needed (in case one needs a different working directory, for example).

Deploy

1. Start the service:

$ systemctl --user status tuya2domoticz
