Homatics B21 remote: Configure the volume buttons to be send as IR

Hi,

with Android TV it is possible to set up the remote to control the TV volume, while the rest of the buttons are still send via Bluetooth and control Android TV.

(That is Android TV 11 on Homatics Box R 4K Plus with B21 remote)

Unfortunately this functionality is lost when re-pairing the remote with CoreELEC.

Is there a way to configure the B21 remote with CoreELEC the same way?

Meaning: Make the remote send volume button presses as specific IR codes for the specific TV?

Thanks for any pointers.

I think the only way is to set up volume settings → IR …
And use coreELEC with IR.
Now you can use the b21 in Android (BT)with the IR volume keys . CoreELEC with IR and volume keys are still set to your audio device.

Nice idea! But as far as I know the Homatics Box R 4K Plus does not have a IR-receiver. Is there a recommended IR USB dongle for this use case?

I was hoping it might be a common bluetooth protocol for all Android TV bluetooth remotes, as the “setup remote app” seemed to be non-homatics-specific.
