Dead Air Unit - Repurpose Controller?

Air unit is dead most likely over heated or over voltage. I have tried resets, multiple voltage inputs from 5v-12v as well as the USB port. The retailer has provided zero help and the Hex support are slow to respond and recommend sending it back to Hong Kong while making it clear they are most likely not going to replace the unit and will most certainly declare a customer problem.

Support refuses to provide an estimated repair cost and the return shipping to HK is $80. It remains to be seen if it makes financial sense to send it back or not.

Does anyone know if the Remote Unit has any usable purpose without the Air Unit? Or do I have a new $700 paper weight?

Thanks

Why not just order another Airunit ?
