I've been thinking about getting one of the 16Amp Sonoff with the temp & RH sensor.
Those things look like fun. I've been using the ESP8266 with Alexa and really like it so far..
But, it's only one-way so far. Off-on commands out, but no feed back from sensors..

And China has a few more ESP8266 D1 mini pcbs in stock...
So many gadgets and so little time..
Monday mail came!! And it seems to be working okay!
