After this update, my CPU temperature has risen enormous. My Health Checker warned me. Checkout this graph:
The drop as the the moment i saw the warning and opened the door where my computer is behind. Anyone else has this?
Can confirm: Temperature has risen from 35Ā°C to 45Ā°C. Not good for my very old server.

Hmm, i see that itās a DSMR process. I see that the DSMR is broken. (dutch smart meter reader). Iāll check it out.
FWIW my NUC temp has raised a couple of degrees. CPU seems the same
havent used the ssh cli interface for some time, but needed to config check today, and this is what is returned, have never seen it before and am not sure if I have a problem 
~ $ ha core check
Processing... Done.
Post "http://supervisor/core/check": context deadline exceeded (Client.Timeout exceeded while awaiting headers)
~ $
on HA 2021.5.2 meanwhile
anyone?
Updated my DSMR installation, and seems back to normal now. It couldnāt start postgresql or something. Rebooted, updated, and fine now. Coincidence that it occurs right after Hassio update.
There is no such thing as āHassioā anymore.
Itās either Home Assistant OS or Home Assistant Supervised.
Yeah, i know, sorry, itās a habit, haha!

Yea, no problem. Just trying to do my part to minimize the confusion caused by the name change.
But I get it. The āproject who shall not be namedā was much easier to roll off the tongue and the keyboard. 
But my automation doesnāt work with project_who_shall_not_be_named.snapshot_full
Seriously: What else can have caused the temperature increase?

I never said the developers were doing their part to eliminate the confusion. I just said I was doing my part.
Yeah, it sucks that with all of the hullabaloo around the renaming in the last couple of years that the project itself hasnāt done what they need to to get the naming conventions fixed after all this time.
As far as your CPU temp issue, I canāt help with that.
Have you tried turning off different add-ons to see if one of them is causing it?

Ok, gonna open an issue on Github 
Ah, thank you for the hint; I never suspected any addons. Will try and report.
After upgrading to 2021.5 I experience huge increase in data usage. I am on a mobile broadband with a data plan of 100 Gb per month and that has been consumed in 2 days. Any changes in this version that could cause this behaviour? I have Onvif cameras configured but they are local only

Yes I have same error. I logged a bug report for it on github a couple of days ago

thanks, I now noticed that, (missed it before because I searched in the wrong repoās) and I had filed an issue on Supervisor btw mine was not an exact duplicate, I reported on āha core checkā
guess 3 issues now will get the attention it needs

Supervisor bloats. Each entity is stored though the corresponding addon has been deleted. How do you deal with it?
What does this even mean?
