Substitute for AVM FRITZ!DECT 440 switch

Hello everyone,
I want my Fritz!DECT environment substitute with other devices.
You can quickly find an Alternative (Tasmota/Zigbee) for most of them.

So far I haven’t found anything suitable for the AVM FRITZ!DECT 440 switch.

There is a very simple from Aqara; does it work directly with the HA Sky Connect?

Or are there others?
I would be most grateful for any tips.
