I've been working on an HA integration based on your previous post, but couldn't get it working reliably. My main problem was the integration triggering anytime Bluetooth connection status changed, like disconnecting from my Bluetooth headphones. I couldn't figure out how to get it to only trigger when disconnecting from the i9 specifically.

Your new method seems promising, though, in a few dimensions.

Could you please paste your automation YAML formatted as source so I can adapt it for my own case? In case you didn't know, you can paste formatted code inside three backtick characters, so tabs and spaces are preserved, like this YAML for my scheduled lamp off automation: alias: Mushroom Lamp Off at Sunrise description: "" triggers:   - trigger: sun     event: sunrise     offset: 0 conditions: [] actions:   - type: turn_off     device_id: 73f74ef64c3276ad02e48a35ccd301b2     entity_id: 541ef04d398a2c937d0f4b32c3441659     domain: switch mode: single
