Bluetooth support for Projecta PM300-BT?

I have an RV and it uses the Projecta PM300-BT system which has an app for iOS and Android and connects via Bluetooth.

I’m looking to get these sensors into HA if possible and I’ve tried using the official Bluetooth Add-on as well as the HACS Passive BLE monitor integration, but can’t seem to see the device nor any way to detect it and it’s sensors.

Wondering if anyone has done this, or if not has ideas on how to proceed?
