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_…

How is what helpful? Stating the issues the HA team faces when considering this change? Or that devices can change while HA is down? Not sure what you’re asking here…

The way I see it there are two possible results: The way it is now. HA reboots and the last_updated is wrong 100% of the time. Yes, we all understand that it did change during boot, but that’s kind of a cop out. Nothing is gained and the result is clearly wrong unless we want to argue minutiae. …

I mean basically what you’re asking for is every entity to restore state, no longer leave that choice up to the integration developer. You can’t just persist last_changed without also persisting the state of the entity. Otherwise when HA starts up there’s no way to know if the state of the entity i…

I’d be happy for state saving to be enabled/disabled at either a global or entity level. Perhaps enabled by default as that’s what’s most user friendly but I do agree it be good to disable for some users. I personally only need it enabled on my dashboard facing entities.

I’m glad this has the largest vote - it is truly a WTH for the ages. I’m all for having a last known state as opposed to resetting everything to an arbitrary time when last booted.

I mean, it did last time too: [image] What the heck is with the 'latest state change' not being kept after restart? Month of "What the heck?!" (2020) Every reboot I loose so much data about entities that I would like to keep on. Last time guest visited my house? Last tim…

I’m just glad after years gone by it’s not still just me thinking “WTH” on this! I think regardless of opinions on how the current last-changed/updated attributes work, there’s an obvious need for a last-known-state-changed attribute in some form. Whether that’s a toggle per entity or just a brand…

just wondering if Scenes - Home Assistant would be helpful. Or doesnt a scene created on the fly survive a restart either…

how could scene solve that my doors get ‘changed’ status even when no one touched them? :wink:

wait, you’re right… I was thinking of the actual state, not the last_changed… my bad, please ignore

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