Something that has always annoyed me is how the “last-changed” attribute is handled after a restart. I understand why it’s changing as it’s technically unavailable but it’s not very helpful when you’re using it in the UI. On my security dashboard I only really care about the time a window state chan…

Made a simple version using a trigger based template sensor which stores the last change of all entities you list in the trigger. template: - trigger: - platform: state entity_id: - input_boolean.test not_to: - unavailable - unknown not_…

Yep, so thought it was worth bringing up again! I can hope, thanks for the link, hopefully shows it’s a well requested feature.

Yeah it seems like it’s been a very requested change over the years so hopefully this gets enough votes to really show that people want it. The logbook is able to show when my window only opened and closed so surely the data is quite easily accessible. Fingers crossed!

Yes, more user feedback in an older posts here: [image] Retain last state change data of a sensor after reboot Feature Requests 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 remo…

The biggest problem is very simple: Home Assistant is offline (during reboot or when shut down). It has no idea what happened during that time. Restoring the last changed would be an assumption, not reality. (Besides that, it actually changes at startup, when connecting).

I’d love to opt into making that assumption for some specific entities.

As the comment below yours mentions - I’d also like to be in control of that assumption too. The chances of state changing whilst HA is updating or restarting is so slim for me that I’d take that risk. Even if that’s just a different type of “last-changed” option, perhaps the “last-updated” attribut…

Sure, but then again, the state does change when connecting to the device.

I just want to know when my windows and devices actually changed states (I know they technically are but in reality they’re not) that weren’t a simple restart is all - in reality they only open and close. I’ve already made a load of manual sensors now but I’d imagine it being a bit misleading for a …

Persistent version of "last-changed" for the UI?
