@ovidiu.pruteanu Got the new probes and everything worked immediately. Such a headache trying to problem solve with faulty probes. Thanks so much for your work on the DH and your help problem solving. Do you have a venmo account I could send a few bucks to as a way of saying thanks?
As another use application: I am planning on using two smart implants with temp probes to monitor attic temperature, garage temperature, and outdoor temperature for the purpose of controlling ducting on a Rheem Hybrid water heater with ducting to the attic, garage, and outdoors. The input air to the Rheem unit will come from either the attic or garage, whichever is warmer. The cold output air from the unit will either be ducted to the garage or outdoors depending on whether I want the cold air in the house or not. I am using Suncourt motorized dampers (both normally open and normally closed) connected to a smart outlet. I am using AtticFanControl from joyfulhouse SmartApp as a temperature differential controller which will turn on and off the outlet (flipping the damper) whenever the attic temperature drops below the garage temperature (or vice versa). Hoping I have the time to do a little modifications to the SmartApp to set it up specifically for this purpose, but as is, it looks like I can make it work with the defaults already in the app.
