I have a customer with an old Color Control GX. The customer wants to use some Ruuvi tag temperature sensors with the system. I know the CCGX doesn't have Bluetooth built in. My question is can a USB Bluetooth dongle be added to the CCGX to allow it to communicate with Bluetooth sensors like the Ruuvi tag sensors? I do this regularly with Cerbos to extend their bluetooth range, but they already have Bluetooth built in. I have never tried it with a CCGX.
I also know Venus OS firmware version 2.80 or later is required to support Ruuvi tag sensors. Will the CCGX run at least that firmware? (I don't know what version of firmware the customer currently has because the install is in a remote location and the customer doesn't remember.)
