A Domoticz plugin to manage Tuya Smart Bulb (RGBW)

With Python version 3.5 & Domoticz version 4.9700 (stable)

This plugin is based on the latest pytuya Python library. For the installation of this library, follow the Installation guide below. See https://github.com/clach04/python-tuya/ for more information.

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

pip3 install pycrypto

See https://pypi.org/project/pycrypto/ for more information.

Assuming that domoticz directory is installed in your home directory.

cd ~/domoticz/plugins
git clone https://github.com/tixi/Domoticz-Tuya-SmartBulb-Plugin
cd Domoticz-Tuya-SmartBulb-Plugin
git clone https://github.com/clach04/python-tuya.git
ln -s ~/domoticz/plugins/Domoticz-Tuya-SmartBulb-Plugin/python-tuya/pytuya pytuya
# restart domoticz:
sudo /etc/init.d/domoticz.sh restart

In the web UI, navigate to the Hardware page. In the hardware dropdown there will be an entry called "Tuya SmartBulb".

Domoticz may not have the path to the pycrypto library in its python environment. In this case you will observe something starting like that in the log:

• failed to load 'plugin.py', Python Path used was
• Module Import failed, exception: 'ImportError'

To find where pycrypto is installed, in a shell:

pip3 show pycrypto

The Crypto directory should be present in the directory indicated with Location.

when you have it, just add a symbolic link to it in Domoticz-Tuya-SmartBulb-Plugin directory with ln -s. Example:

cd ~/domoticz/plugins/Domoticz-Tuya-SmartBulb-Plugin
ln -s /home/pi/.local/lib/python3.5/site-packages/Crypto Crypto

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

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