Graham Looks like it can. Google "Geekcreit Sonoff 2 Channel Relay" and go to the tasmota.github.io site. Fiddly though!

Graham Use a USB to serial converter set to 3.3V. Wire it to the RXD and TXD pads on the board. Ground GPIO0 when powering up to put it into flashing mode. I'm going to get one to try.

Q: Hi , do you have these switches without neutral ?

Graham In the UK, wiring at the switch typically does not include a neutral (just live in and switched live return). Hence the question - no neutral - no power supply! Batteries would be needed. I think this is now changing for modern houses or re-wiring.
