FWIW, if your HASS is running on a device (like a Raspberry Pi) that has Bluetooth, you might be able to get away with a custom component like https://github.com/custom-components/ble_monitor instead. Of course, if your setup is working for you already there isn't much incentive to change it.
Anyone serious about running HASS, or home automation in general should move away from a Pi because it's not cut out for running a home, the SDs are fragile and need decent, clean power and the performance isn't stellar when you've got a lot going on.
It's a nice, cheap starting point, but something like a NUC or similar is the next step for a reliable machine to run it on and won't suck up electricity.
