Re: [mh] Installing Tasmota firmware on Sonoff OTA devices

Paul,

Currently three devices (Basic R3，RFR3 and Mini) can have Tasmota 
firmware installed OTA (over WiFi).  I successfully upgraded the 
original Minis that came with R 3.5.0 firmware, meaning V2 of the OTA 
protocol, meaning no special software required.

Many other devices can be flashed using either a serial programmer 
(requires hardwired connection) or OTA using custom software (ex: 
tuya-convert).  See this site for details about what devices work and 
instructions for installing Tasmota:

Good luck!

Jeff
