Hi @Circuitman , since I already made a suggestion this morning related to YoSmart devices, I’m feeling a bit like a “pusher”, but am doing it only because I’ve had success. YoSmart (YoLink) makes a temperature/humidity sensor that’s LoRa that might be worth considering. I’ve used these and “integrated” them with Particle devices via IFTTT and wonder if that might be something worth considering for your application.
