App is only okay….

If the thermostat knows what the temp is, 1) why does it have to be off? 2) why not able to see in the app? Should be able to see what the temp is at all times in the app!

It functions like the thermostat on the wall, it’s better in that the touch sensitivity on the wall is way off, too sensitive, go near it and it acts like you’ve touched it, so mainly use the app. This is why 3 stars and not 2.

Sometimes after an iOS update, (or if you try to connect when not near enough), app loses connection to thermostat and loses the name you gave it, have to pair again. Lame. It should at least keep it in memory.

Need to update the app. Dometic is huge, use some money to develop this app, most who use it don’t give feedback here.

Does not work with latest IOS

The app did not work for me since Fall 2020 (it’s April 2021 now). A few weeks ago it didn’t work, just crashed every time. Now it works, not sure why.

Poor instructions

If only the app told you to enter the two digit code twice I would’ve been connected weeks ago. We bought our toy hauler with the stat already installed and info is hard to find. Also need to display current temp in the app.
