The Gosund KS602 is a smart switch which I bought for around $28 CAD for two ($14 CAD each). It has a ESP8266 and can run Tasmota. The unit is very simple to open and easy to reflash with Tasmota.
Configuration[edit | edit source]
After flashing Tasmota, I had to configure my unit with the following template since the one on https://templates.blakadder.com/ did not work for me. This template will have the LEDs turn green when on and red when off.
