calor BT Customer Insights

1. Therefore I can't pair it to my phone anymore even though the thermostat does show up when wanting to pair a new Bluetooth device.

2. Most households have more than one person who might want to adjust the heating! Can't get the firmware update to work, it just says failed straight away, but that doesn't seem to be a critical problem.Modest and simple app, that can be improved, of course, as they all can be.

3. Would love to have it solved)I thought this was going to be very useful as many of my radiator thermostats are hard to view, but having spent several days setting everything up, I discovered this morning that all my devices have disappeared from the app.

4. I think it's the app that isn't allowed to pair on the phone as it works with another phone of the same brand but one previous OS installed.Just got my smart thermostat a d connected it with the app.

5. First it worked totally fine, but after updating the firmware of the thermostat tot 1.46 the screen goes blank (instead of showing PAIR and a pairing code) when holding the dial for 3 sec.

6. Why doesn't the app show that information? You also need to go back to the 'room' to go into the upgrade menu.First of all, i could get everything to work, but it involved some pain.

7. Reading up on the device, it can send a lot of information such as signal strength, battery condition, temperature, firmware version etc.

8. Half the time i had to restart the app to get the dialog for entering the ID displayed by the device.Pretty useful actually, and much easier to make adjustments than fiddling around with the buttons on the thermostat.

9. Used to run 8.Since the update of 14/12/2020 the settings are not saved anymore and I need to link every device every day again.

10. A useful addition would be a way to export the devices from one phone to a file and then import that file to the app on another phone.

11. So.. without Bluetooth the smart radiator thermostat isn't that smart anymore... (Ps.
