I know this is an old post, but it fits my issue as well. My sensor started reading 5 cm overnight. I installed it last night and this morning the sensors are reading 5 cm, and nothing I do fixes the issue. What else can I try? Id like to use the built-in distance sensors instead of external switches, but will run a wire if needed.
More testing.
Removing the clear cover solves the issue. I can set the cover over and align the hold or the sensors, but not seat the cover on its tabs and I have no issues. Seems like this only happens when it’s up to operating temp in the garage.
