A Domoticz plugin to manage Tuya Smart Plug (single and multi socket device) This is a modified plugin from the modified plugion by sincze, The sincze plugin used a script called by cron and the plugin just created the devices. Now all is managed by the plugin and using the tinytuya API (the pituya was obsolete and no longer supported).

Multi socket has not been tested. I only have 1 socket. Keep in mind I am not a Python developer, pertinent remarks are appreciated. Plugin is provided on best-effort.

With Python version 3.7.3 & Domoticz version V2022.1

This plugin is based on the tinytuya Python library. For the installation of this library, follow the Installation guide below. See [`https://github.com/jasonacox/tinytuya] for more information.

For the pyaes Python library, you need pyaes. pyaes can be installed with pip:

pip3 install pyaes

See [https://pypi.org/project/pyaes/] for more information.

Assuming that domoticz directory is installed in your home directory.

cd ~/domoticz/plugins
git clone https://github.com/Tatroxitum/Domoticz-Tuya-SmartPlug-Plugin
cd Domoticz-Tuya-SmartPlug-Plugin
git clone https://github.com/clach04/python-tuya.git
pip3 show pytuya #show pytuya path
ln -s ~[pytuya path]/pytuya pytuya
python -m tinytuya scan #see under for devID & local key extraction
# restart domoticz:
sudo /etc/init.d/domoticz.sh restart

If the watt values are very low (for example 3W) there is an issue in Domoticz and the values in kwh are not calculated domoticz/domoticz#5326

Like other plugins, in the Domoticz-Tuya-SmartPlug-Plugin directory:

git pull
sudo /etc/init.d/domoticz.sh restart

DPS should only includes values that correspond to plug's dps id. Be careful some devices also have timers in the dps state.

DPS group can be used to group multiple sockets in one Domoticz switch.

Helper scripts get_dps.py turnON.py and turnOFF.py can help:

• to determine the dps list
• to check that the needed information are valid (i.e. devID and Local Key) before using the plugin.

Recommanded method: Linking a Tuya device with Smart Link steps 1 to 3 then Listing Tuya devices from the Tuya Smart or Smart Life apps 1 to 3. Other steps are not mandatory.

TinyTuya has a built in network scanner that can be used to find Tuya Devices on your local network. It will show Address, Device ID and Version for each device. python -m tinytuya scan

• Special thanks for all the hard work of clach04, codetheweb and all the other contributers on python-tuya and tuyapi who have made communicating to Tuya devices possible with open source code.
