Hey guys, I've just tasmotized a device for the first time and it happened to be a Sonoff 4CHPro R3. I didn't solder (although I have everything required), just put the connector cables and bent them slightly into the holes.
I was looking for a driver and decided to try this one and I can confirm it works! However, I have no idea how to enable the interlocking or inching modes. The official page says that they are app controlled and available for separate gangs, so I will try to figure out something. Do any of you guys have ideas on that?
