Need working AC500 BT connection before I start.

[Wuastr]

My grand plan is to implement Bluetti2MQTT (add-on) first and then upgrade with your ESP32 solution to allow WLAN connectivity. I want to establish a baseline before diving into ESP32 programming.

Since Warhammerkind seems unavailable to ask directly, I hoped for this back door into finding out why I cannot establish BT. I read that many have successfully connected their AC500 so there is hope.

The AC500 never goes out of BT disconnect mode. Not even briefly. It works with the Bluetti app. Both internal and external BT adapters are recognized by HA. I only use one at a time.

I am running HAOS on a standalone old Surface Laptop. I wanted to take advantage of the add-on store (and the laptop was useless for W11). A good repurpose. I did try Ubuntu first with Home Assistant Container and actually had an AC300 talking to HA, but that was on another device that died.

In the Log I read that my AC500 is found.
"Found AC5002308000844715: address B8:D6:1A:BE:5D:2E"
Then it shuts everything off.
"s6-rc: info: service legacy-services: stopping
s6-rc: info: service legacy-services successfully stopped"

Here are excerpts (the beginning and end) of the log:
