Well, I must have jinxed myself. Yesterday morning early at different times between 04:00 and 08:00 all six of those motion and contact sensors went off line like they were. Tried off and on all day yesterday and today. None will come back.
Nothing was changed here to cause the good or the bad. Must be - could only be something that Wyze is doing. It was after their AWS problems. But we’ve been hearing they are doing some actions - like blocking HA users - so maybe/probably that has something to do with this recent improvement then loss with me.
Bottom line is: I believe now that Wyze is hammering our V1 sensors due to issues with HA.
