Since the install of 2021.9.2 suddenly my HA CPU Load went from before ca. 1-2% up to ca. 60%. Ideas?
Any errors in your logs?
This thing just happened to me, also within the past couple days. Mine turned out to be a z-wave addon. The old zwave integration was recently deprecated, and they came out with the newer one that’s now auto-detected and I think I may have clicked on it but never finished setup, so it was in a partially configured state. I don’t even use zwave, I was just curious to see what’s new. Anyway, go to ‘Supervisor’, then to ‘add-ons’ and look through your installed add-ons. Each one will tell you how much cpu it’s using when you open it and inspect the settings. Hopefully you fig it out. For me, it was the z-wave at 75% cpu, as soon as I uninstalled it, my system dropped back down into single digits.
Was able to resolve it yesterday with some help from a Zwave JS developer. I had the exact same thing - 2 Zwave integrations running.
When I install Zwave JS MQTT then (since HA 2021.9.0) Zwave JS is automatically suggesting to install itself (which I have done)
I have now uninstalled Zwave JS MQTT + also had to uninstall + reinstall Zwave JS → now CPU load is back to 1% (as it should be)
