Anyone have one of these and have any troubles? I was running the smokehouse yesterday and running batch on the stove. So, I needed two temp probes. I had my IBT-6XT on the smokehouse and ET-733 monitoring the braunschweiger on the stove for IT and water temp. The Inkbird just quit connecting to my phone. It read all the temps on the unit, but the phone wasn't receiving anything. I powered off the remote unit and closed the phone app and restarted both and nothing on the phone. 1/2 hour later it was working and dropped out. Maybe they can't work in the cold?? Anyone have any problems like this or have an idea?
