Dashboard stops updating/goes to sleep after 10 minutes or so

Hi,

This is my first request, so I hope I’ve given all the right info, but will come back with more if I’m missing some.

I’m running Home Assistant 2021.12.6, Frontend version: 20211227.0 - latest, as a Docker on a Synology DS1817+ running DSM6.X. I updated to this version from 2021.10.something, and had to spend an hour or two fixing various integrations that didn’t work. Somewhere along the line it seems that my dashboard now doesn’t respond to entity updates after 10 minutes or so of inactivity.

It was fine before, and always updated immediately that something was changed. First sign that something is wrong now is that, upon restarting, the dashboard displays the usual “Home Assistant is starting…” message, but these never go away - even once it’s all booted up fine. Only a browser refresh clears them and the normal dashboard appears. Similarly, immediately after a refresh, if I update a light from elsewhere (ie a physical switch), it will update immediately on the dashboard. Wait 10 minutes and try the same thing and the entity does not update. Refresh, try again and it’s fine. 10 minutes or so later and the same problem. That happens with lights, input booleans, anything that gets an external state change.

Because so much has changed at once I do not know whether this is an issue with the version I’m running, or whether it is something to do with various tinkering i’ve done to integrations to get other bits and pieces to work.

I don’t have any errors in my logs, (other than warnings about TuyaLocal integration), and there are no errors in my Developer Console once the dashboard is loaded correctly. Makes me think it is a fundamental issue with this version of HA but I haven’t seen any mention of it elsewhere.

This version of HA was the one that is classed as “latest” in the docker registry, so am assuming it is fine?

I am seeing the same behaviour on two different mac computers using chrome, as well as on fully kiosk from a Fire HD 10.

Does anyone know where I should start to get his working?

Install 2021.12.7

thank you that seems to have fixed it. Weirdly on the synology docker list, 2021.12.7 wasn’t listed - it went straight from “stable” which was 2021.12.6 to some dev versions 2022 which looked a bit scary. But i have since worked out how to pull a new image and I ran that with no problems.
