I have very very similier board. I have tasmota on it and it's working great as a "smart" speaker switch. Wondering about adding a dallas temp sensor. I am searching now for uart/tasmota data and pins/gpio. Any tips or clues for me? Thanks.
You need to make a dc 8 dc 16 and dc 32 and you would get a lot of business from people like me that dont want to waste time with programming arduino or raspberry pi
I use mine as a speaker switch. 1 amp 2 sets of speakers. Big n small. In Tasmota I have relays 1&2 and 3&4 tied together with rules. I'm pleased as punch with it.
