I have a motion sensor that has false motion after the ota update. Support told me to replace the battery and it fixed it. The battery was showing 76% charge so I did not think it would fix it,but it did. You have to the Panasonic battery, others do not work. I found them on Amazon 5 for 10$ prime.
Things that were wrong with update.
No way to put old software back in.
Did not test at low voltage.
Did no customer testing.
The firmware should have been tested at min and max voltage.
What should be done:
They should release firmware that will work to the same voltage as the old firmware. Battery reporting has to be fixed.
The new software has to be tested before release.
It would be nice if I did not have 2 hours of work for a bad release of firmware on ST device. They should work.
