Install Tuya Convert on a Raspberry Pi

Flash Device

Detailed instructions can be found:  https://github.com/ct-Open-Source/tuya-convert


You will need to hold down the button to get this switch to flash.

> ./start_flash.sh 

Configuring Switch

Configuring WIFI

Connect to the flashed device by looking for it's SSID - tasmota-####

Browse to http://192.168.4.1/

Configure the SSID and password.

The dimmer will reboot and connect to your wifi network. Check your router to find out it's IP address and connect to it via your browser.

Set the GPIOs

3 Way Setup

From the Configuration → Configure Other screen, input the template and friendly name:

Template: 

{"NAME":"Treatlife 3-Way","GPIO":[0,0,0,0,21,158,0,0,22,18,9,0,0],"FLAG":0,"BASE":18}



You should end up with a configuration that looks like:





2 Way Setup

> backlog module 18;gpio4 52;gpio5 0;gpio12 29;gpio13 17;gpio14 0;switchmode 1


Homebridge Config

For integration with Homebridge, we are going to use the mqttthing plugin and run all of the commands through an mqtt server.


Tasmota Setup:


Homebridge Config File

3-Way Setup:

        {
            "accessory": "mqttthing",
            "type": "lightbulb",
            "name": "garage-light",
            "url": "http://192.168.1.50:1883",
            "username": "homebridge",
            "password": "pass",
            "topics": {
                "getOn": "stat/garage-light/POWER1",
                "setOn": {
                  "topic": "cmnd/garage-light/POWER2",
                  "apply": "return 'toggle';"
                }
            },
            "onValue": "ON",
            "offValue": "OFF",
            "startPub": {
                "cmnd/garage-light/POWER1": ""
            },
            "confirmationPeriodms": 1000
        },

Out of Sync

Sometimes the switch may be out of sync with what it reports to homebridge. When you click Toggle 2, the Toggle1 should reflect the current state of the light. If this is not the case, click the Toggle 1 button.
