Thanks for responding Ray. I love this implementation, and hope to use it to its potential.
I’ve been testing more on this thing, and hove found that the modifications I made earlier worked for about a day. It seems to be strictly temperature related. I have now completely removed all of the covering, and I still get the 5-3 cm measurements from the sensors.
Here are some temp measurements:
Temp at ceiling mount point: 31 degrees C
Temp on wifi chip: 35 degrees C
Temp outside: 26 degrees C
