Out of my league here but trying to figure it out. I did have a bestlibre caddy configured I think when I set this up but it appears its not maintained anymore so I switched back to straight duckdns no reverse proxy. I mean if that is even the problem I’m lost here. This used to put a battery sensor up in HA so I could recharge the thing instead of totally draining it.
i only use this in my tablet so i use my internal address http//xx.xxx.x.xx:8123 and also some times i get the same message but the sensor still works there is an app call Ariela - Home Assistant Client it has a lot more sensor and features and is easier to use
Thanks lol guess u heard me whisper your forum name. I think I tried using my local address in the %HA-ADDR variable. Is that what you did? Yes I’ve seen that app kind of waiting for an official android app though.
