I’ve definitely forgotten to close mine once or twice, even though my custom (LoRa) integration is just simulating pushing the button on the wall by closing a relay contact and watching for closed status with a reed switch, it means I can do it from anywhere.

It’s a shame that even “cheap” versions are hundreds of dollars, because the perfect absolute position sensor would be a “draw wire displacement sensor” (goes by a few variations on that name).

Basically a spring-loaded spool of wire with a multi-turn position sensor, rolls in and out like a tape measure.
