Garry, when I look at the price indeed I cut put such a separate board at every sensor location. Think that is what you mean (instead of wiring N sensors to a single board)? That might be a solid solution, but then again I come back to my 3 major problems: time, time and time. Is there some kind of ESP8266 software/firmware/... available that I can communicate and control it via MQTT from my Node-RED flow. That would nice, because then I could keep my main focus on Node-RED. Really don't have time to learn programming such a board. But looks interesting !
Colin, seems that wife firmware version 0.0 cannot handle external resistors. But you are right. I can at least try it. Will give it a try next week ...
