I too recommend setting up Home Assistant with Bluetti-MQTT. You’ll need to roll up your sleeves a bit but it’s worth it in the end!
That looks great! Thanks for you suggestion
If someone is using Home Assistant, you can also use my integration now which is based on bluetti_mqtt: GitHub - Patrick762/hassio-bluetti-bt: Bluetti Integration for Home Assistant
I also asked Bluetti about more info on the bluetooth addresses they used but got no real answer.
The biggest problem right now is that I cannot add new Bluetti devices since I can’t buy them all. It would be great if there was a way to test the integration on devices that Bluetti provides.
