Gosund KS602
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.
Tasmota
Flashing
All the pins you need to flash Tasmota are exposed as a test pad. Use some test clips to attach to 3v3, GND, TX, RX, and IO0 and flash Tasmota using esptool.
To get into programming mode, short IO0 to GND. Using a 10K resistor to GND won't work!
Configuration
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.
{"NAME":"Gosund KS-602","GPIO":[32,0,320,0,0,0,0,0,0,0,224,0,290,0],"FLAG":0,"BASE":18}
