This is my first project and I’ve been reading for 2 days before replying. I’m a beginner at programming & appreciate the patients. However I am unable to see/understand how to get the Photon to do multiple things. I’m trying to open/close/(Status) of the garage door while also integrating a DHT11 sensor reporting in Farenheit. Any assistance & expertise would be greatly appreciated & hope a chuckle is had at my nievetie…
Found this link/code as well for the Temp Sensors (no Blynk)
