The hardware I used is mentioned above.

The steps are from the [Tasmota wiki](https://github.com/arendst/Sonoff-Tasmota/wiki/Hardware-Preparation).

**1) Connect the wires from the USB Serial adapter to the TH10**

Placement of pins may vary. Important to [swap](https://github.com/arendst/Sonoff-Tasmota/wiki/Hardware-Preparation#serial-connection) the RX and TX cables.

**2) Check your serial-to-USB adapter so it supplies 3.3V power instead of 5V**  
There is a black clip that you can lift and place over 1 pin where it says 3v

**3) Flash the chip with [NodeMCU PyFlasher](https://github.com/arendst/Sonoff-Tasmota/wiki/Flashing#nodemcu-pyflasher)**  
I downloaded the latest version from [here](http://thehackbox.org/tasmota/release/sonoff.bin)

**4) [Configure](https://github.com/arendst/Sonoff-Tasmota/wiki/Initial-Configuration#using-web-ui) the wifi settings**

**5) Install [MQTT](https://apps.athom.com/app/nl.scanno.mqttbroker) on Homey and set it up**

**6) [Configure](https://github.com/arendst/Sonoff-Tasmota/wiki/MQTT#configure-mqtt) MQTT on the Sonoff device**

**7) Configure the module that it is an TH device and assign the sensor**

**8) Add to homey as an new device**

This is a short explanation you can find a lot on the Wiki and in this [Topic](https://community.homey.app/t/itead-sonoff/119)
