Domoticz-Tuya-SmartPlug-Plugin

A Domoticz plugin to manage Tuya Smart Plug

ONLY TESTED FOR Raspberry Pi

With Python version 3.5 & Domoticz version 4.9700 (stable) and 4.9999 (beta)

Prerequisites

This plugin is based on the latest pytuya Python library. For the installation of this library, follow the Installation guide below since pip will not install the latest version commited few days ago. 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.

Installation

cd ~/domoticz/plugins
git clone https://github.com/tixi/Domoticz-Tuya-SmartPlug-Plugin
cd Domoticz-Tuya-SmartPlug-Plugin
git clone https://github.com/clach04/python-tuya.git
ln -s ~/domoticz/plugins/Domoticz-Tuya-SmartPlug-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 SmartPlug".

Known issue

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-SmartPlug-Plugin directory with ln -s. Example:

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

Updating

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

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