I think it is very interesting.

Either that translator device is required by HomeKit or it is required for ADRC to work as a non standalone system but the description points to an onboarding system such as ADRC in my opinion.

The current ADRC version uses a hub (the umbo is the hub released when the arduino shield was released) to host the ADRC server software. This component software of ADRC is what they are converting to put into the BLE mesh Telink chip. (The part of the porting they have not yet been able to complete.)

Really need to see the specs or user manual for the device. Can we hunt those down? I don't think it is released yet so probably will have to wait.
