Motion sensors 'Last change' time resets after restart - seems this is new

[litfoo]

hi all,

I noticed recently that after a HA restart all my motion sensors would all reset - so instead of showing when motion was last triggered/changed it is showing the count up time of when HA restarted

I don’t think this occurred before on restarts and am seeking the community advice

also, as there is no actual motion, I assume this would not set off my alarm which are linked to movement

thanks in advance

Retain last state change data of a sensor after reboot

I would really like to see the last state change of an entity retained through a reboot. My use case: I have a binary sensor talking to a remote Hikvision camera’s PIR motion in my mother’s apartment. I know I can drill down into the state history, but it would really be nice to know that the at a glance “12 minutes ago” is an accurate indication of last motion detected, and not just the time since the last reboot. Thanks.

I’m pretty sure that has been like that forever.
