@Julie-Adam Have you considered disconnecting the air-line from the controller and reconnecting it to the air-head ?
The cranium woodframe is probably interrupting signals which possibly
explains the coupon fascination...
@Westie That feature can also be used with the Arduino Nano, or any other ATmega328P-based board.
I had NRF24 + RFM69 running for a couple of days using a Nano as an Ethernet MQTT gateway and it worked fine as far as I remember.
@Martin_Smith Microwave backscatter can show rain out to some distance. At airports an optical method is used as it also covers fog and snow. It really comes down to why you want to measure distance in rainy days and what sort of distance you intend or need to cover.....
Reporting back: I installed the Gen2 Emporia Vue, and it "just works" on the first try. Ironically, it reports the same amount of power for my refrigerator as the far less expensive TopGreener power module, so I guess the TopGreener is more accurate than what I had thought. At least the Emporia Vue's built in graphing is far superior and involves no switching, so overall I'm glad I made the upgrade.
