Comet DECT 300 not working properly

[Nico111 (Nico F.)]

Hey Community!
So I have setup and got my Comet DECT 300 Thermostates pretty easy.
But I’ve encountered some weird behaviours:

• When I set the target temperature, it works but only for a few hours. after a few hours they change back to the ECO Mode Which is the temperature set in the FritzBox UI.
• When I set a new target temperature, they don’t update immediatly, it takes some minutes. But if I press the Button, to activate the Display, they change temperature immediatly.

Besides that, they really work stable. Thanks to everyone contributing!
I’ve searched the forum for some answers, but didn’t find any.
If there is a forum already talking about this, please link it!
Thanks!

Did you configure a schedule in FRITZ!OS for your device? Maybe the reason for your first issue.

Second one is easy to explain.

I am afraid a faster solution is not possible. The F!Box needs up to 15min to determine the connection state for a device. Let me quote AVM’s support page: Smart home devices such as FRITZ!DECT radiator controls, FRITZ!DECT sockets, and FRITZ!DECT Repeaters function according to the standard DECT ULE (Ultra Low Energy). Devices that use this radio standard only communicate with the FRITZ!Box at greater intervals. When the FRITZ!Box is restarted, for example after a FRITZ!OS update, it may take…

I’m sorry it’s a Comet dect 300.
So I’m talking about the thermostates, not about power plugs …
I’ve updated my post.

Did you configure a schedule in FRITZ!OS for your device?

not manually but maybe it was setup by default. I’m going to check this!

Thanks a lot!
