This thread clearly shows that people have different conceptions of stability. I mean some people were happy with windows 95 while the internet was being run by the fantastically stable and secure openbsd.
Instability caused by an update is one thing, but on any particular release I see stability, in that if you leave it alone HA never needs restarting. Other than that it chugs along turning on and off my lights and HVAC, measuring my power usage, telling me when the tide will be high, when to put the bins out and what the weather will be and has been, showing me my cameras and when my packages will be here, turns my speakers off so I don’t wake people up and turns them on when they need to wake up. That is stable IMHO.
What is broken? I feel like people always exaggerate that the system is broken, but then it’s just an integration or some small thing not working. For me a broken system doesn’t run anymore or a large and vital part of it doesn’t work as expected.
In my case some of my lovelace is gone or blank. Trying to insert it manually did not help. At the moment I just restore my proxmox to the previous version.
I was using OH some time ago, but moved to HA more than 2 years ago.
I have 68 lights, 65 switches, 600 sensors, 200 binary sensors, 15 Add-ons, some custom components and a lot of automations (all my lights are automated quite complex for examle - I do this in python with AppDaemon).
And I run KNX, ZigBee, Onewire, Modbus, esphome and some other stuff. All this is running on a 180€ NUC and I’m very happy.
The only case I had stability issues was when I was testing a custom component (=> not developed by HA-Team). But you cannot accuse HA for that. I removed it, and stability was great again.
So in my opinion, yes there are frequent core updates, but if you read the breaking changes and run a config-check before the update (there’s an add-on for that), this has never been a problem for me.
I forget to refresh… after refresh everything is gone. I guess something is making a problem gotta to do with HACS. Which already being update to the latest
