I have a few of these switches as well. Would really like to use them in the areas of my home where there is no possibility of running neutral wires (flat roof).
It doesn’t seem to be possible to serial flash them with Tasmota due to no obvious 3v3, gnd, rx,tx etc. Has anyone else seen these Eachen no neutral switches and perhaps had any OTA success?
I’ve got a 3 gang model and a few of the 1 gang. Not much difference between the boards as far as I can see.
I haven’t had any issues with these switches turning on randomly. Although, they are still on the test bench. Not installing until I can flash tasmota.
