recorder is enabled by default. however, when you are using docker it might be possible that the default file data base (it’s folder) is not mapped to a persistent location outside the container (resp. in the host file system).
however, I really do not know much about all this docker related stuff. my recorder suggestion was just a shot into the blue. if I would be facing this problem I might just try to set up a relational data base like MySQL or PostgreSQL as a target for the recorder.
Restoring the states depends on the recorder. What are your settings regarding the recorder?

I know it’s different, but if I wouldn’t know home assistant I could have assumed it had something to do with USB
To be honest having an information about the actual percentage state of opening is actually useless anyway. I just need the information if it’s properly closed which could be achieved with a simple reed relay.
Having the sensor on the moving parts also comes with other challenges anyway. I used a cheap curly telephone cord to connect the sensor to the ESP8266 but it’s actually already worn out and thus hanging low when the door is open, as the normal state is that it is extended when the door closed
I installed an ultrasonic Sensor at the lowest segment of the garage door. It mostly does it’s job, though it is unreliable when the door is fully open, as the sensor tilts towards the open end and the distance is then too long. Also someone standing in the opening might block the sensor.

at the cost of large upfront construction costs
You forgot the large costs of operating, the large costs of maintaining, the large costs of nuclear waste disposal and the large costs of deconstruction of nuclear plants.
Yeah, other than that it’s a great viable way for few very large companies to make great guaranteed profits as the tax payer will take care of the risks.
If all the subsidiaries that went into nuclear power the last few decades went to renewables instead Germany would have no issues at all, but hey… giving tax payer money to some very few giant energy companies is more important than creating a Europe leading renewables energy sector that does not rely on russian fossils or nuclear material.
You should know that nuclear power is very expensive while renewables are absurd crazy cheap. I’ve been to a German Endlager and it takes years and BILLIONS of Euros just to seal this thing off. Guess who is paying? Mostly tax payers.
There’s be no company in Germany which would be willing to run a nuclear power plant if they were responsible for the permanent disposal of their waste on their own instead of letting the tax payer pay (most of) for it.
How is battery life in this cold environment?
is the history of the values available after restart? like the graphs shown when you click a sensor entity?
