You're not limited to the Aranet4 app. The device speaks Bluetooth and there are Python and Go libraries for parsing the protocol. There is also a Prometheus exporter for it.

You will need a BT -> HA relay, but you can do that with any ESP32 board and ESPHome.

I'm running hass on a raspberry pi 4 and its built-in bluetooth works fine, no extra setup needed.

Only for huge distances. I have mine connected directly to the BT of the mini pc I use to host HA.
