Tasmota on Sonoff S20 and S26 Smart Plugs
After failing to install Tasmota on some Australian certified smart plugs using tuya-convert I embarked on dismantling some Sonoff S20 and S26 smart plugs and flashing Tasmota on them using a CH340G USB to serial adaptor. I purchased the CH340G USB to serial adaptor from eBay, and you can see it below. So, starting with the S20 , there are some good instructions on flashing this device in the Tasmota documentation . I firstly disassembled my device, and had a look at the board. You can see there are various sets of header holes, but it is those near the button that can be to be used to flash the device.
