Support for AVM Fritz DECT switch 440 and Light Bulb 500

AVM recently introduced a new light bulb Fritz DECT 500 and switch Fritz DECT 440. It would be great if they could get added to the AVM Fritz DECT smart home integration.

Yes of course, it would be great and even the switch 400… Thank you for your question… I need it too

I would be very happy if the programmers at HA could make it possible … Thank you


Has anyone tried the Fritz 500 bulb yet? I’d like to get one to use a little further away from the hosue and so DECT is ideal, but dont want to spend the money yet if its not going to work.

I also got a Fritz DECT440 and was happy the temperature sensor was directly discovered.

Unfortunately no switch entities show up, so it currently only acts like an expensive temperature monitor :sob:

Would be great if the AVM Fritz integration could be updated to support switches/buttons of Fritz DECT devices - if I had any clue of programming I’d try myself.

If it helps - here’s a link to the working DECT adapter for ioBroker on Github:

+1 from me. Would be awesome to have the switch entities of the dect 440 switch in Home Assistant.
I’m still hoping, that someone is gonna implement it.

It is not discovered. Is it possible to set a bounty on the integration of the Dect 500?

I looked into it and right now we have to wait for the underlying python lib to release a new version, until integration into HA can start.
The lib owner already implemented support for DECT 4XX buttons and DECT 500, but has yet to push a new package release.

DECT 500 integration looks pretty straight-forward, I’ll see if I can borrow a device, as I don’t own one and don’t plan owning one.
DECT 440 looks slightly more complex, but I do have devices at home.

AVM provides them for developers (ask the press department).
If no luck there, please contact me I can lent you mine.

The beta firmware enables the humidity sensor of the dect 440 switch. I guess this sensor will find it’s way in HA sooner or later?
