That’s even more strange.
Totally random …
The downward sensors and VPS on my MP suddenly stopped working last year (VPS stopped working - no warning. 😱) … couldn’t find anything wrong with it that was fixable.
I re-flashed the firmware and it was fine again, and has been ever since.
I’m using an old (and modded) firmware so, being non-standard, I’m not even sure how you might try the same (someone might know), but there certainly wouldn’t be any harm in trying by doing so.
