Addig Homey Bridge as a extender to Home Pro 2023?

Athom support replied to a user a while ago, it’s indeed only possible to select the transmitting antenna for 433MHz in Satellite mode;
Choosing / selecting which antenna should process a received signal from device Y is not possible yet.
The bridge as Satellite can NOT be used yet as 433MHz receiver
Here’s that particular post in this thread

In English:

It is true that at this moment the Bridge cannot yet be selected as a receiver. Development is aware of this, and for now it has been built in a way it’s impossible both the Bridge and the Pro receive the same signal and therefore perform actions twice. So it remains to be seen how this will be resolved. It is therefore on the roadmap, but we cannot yet guarantee whether and when and in what form this will be implemented.
