Hello. I'm looking for project code to run (multiple sensors) temp/humid. gas, motion and possible 1 other sensor. I'm using esp8266 and Blynk. I would like to use a 9v power supply. I have also CD74HC4067 multiplexer. The ones I have tried have all been wonky and I'm looking for a code that works. This is a very important project for me and I thank you in advance.
