so susah. you want to convert the 1 switch into 3 gang?
why not just buy the 3-4 gang RF switch? not from iTeads but other makes
No, it's already available in 2/3 gang
What I intend to do is to flash custom firmware so it can be paired directly with home assistant or samsung smartthings
They already got alexa skill with ewelink but not working really well. Alexa would definitely work better on this if it can be paired with home assistant.
This one is wifi switch, better than rf since you can get on/off status and pretty much the same price
Yes, there are other wifi switch from other company but only itead based switch like this which the firmware can be modified so far.
Right now I'm just not sure how the guy connect gpio pin to his usb ttl.
Appreciate feedback from anyone here who deals with electronics​
