Battery Usage from Bluetooth Transmitter

[jamesonuk]

Not an issue I know but discussions aren't enabled here and I didn't get any response elsewhere so apologies...

I have been playing around with Bermuda and some Bluetooth proxies and the from what I understand to get this to work in Android I need to enable the Bluetooth transmitter in the companion app?

First question is about what the real world impact on battery usage is here. Is it going to be significant or will it largely be swallowed up by having Bluetooth on anyway?

Second question is presumably I can turn this off when not at home through HA but will that through up any issues with Bermuda if the transmitter is potentially getting turned on and off or will it be no different to it just going out of range?
