👋 Welcome!

I have created this repo for the scripts that I use to monitor the power consumption at my home 🏡.

It is a personal project, but please reach out if there is anything to improve, or something that you find interesting.

Installation

 conda create --name tuya python=3.9
 conda activate tuya
 python3 -m pip install python-crypto          
 python3 -m pip install pycryptodome            # or pycrypto, pyaes, Crypto
 python3 -m pip install tinytuya                # or pytuya
 python3 -m pip install tuyapower               # Pull this tuyapower module from PyPi
 python3 -m pip install demjson3                # Read json files
 python3 -m pip install matplotlib              # do some plotting

Setup of TuyaPower

Follow the instructions for Tuya Device preparation from TuyaPower and read the Notes. They are pertinent for using these scripts after the first time.

As a result, you should now have in the root folder the following files:

  • devices.json : most important one - contains the keys.
  • tinytuya.json : configuration data with the credentials that you used to scan.
  • tuya-raw.json : General information about the devices, contains the mappings.
  • snapshot.json : Only created if you answered Y to Poll local devices? (Y/n). It has the current reading values of the device.

Scripts

This contains examples scripts for using tuyapower.

Check the main Example.py from TuyaPower.

washing_machine.py

I created this script to monitor the power consumption during a wash. This script:

  • Gathers the device info and establishes the communication with it.
  • Has a loop in time to retrieve the information from the smart plug.
  • Saves the reading to a txt file with name the time stamp.
  • (Optionally) plots the power consumption.
