Hi guys
I recently bought a new Miele fridge-freezer and a washing machine and added them to Home Assistant with the Miele integration (official, non HACS). It worked fine for a week then suddenly I get NaN errors in mini graph card and unknown in Entities card about every 10 seconds on and off.
I think it started after a HA update or when I added the fridge and washing machine to a new test install of HA.
I have tried shutting down the new HA install, deleting the Third party apps HA entry in the Miele app and setting up the Miele integration again, and changing the Home Assistant Instance back to my old one.
Anyone having the same problem? Here is a log and some screenshots, please tell me if you need something more.
- Installation method Home Assistant OS
- Core 2026.4.2
- Supervisor 2026.03.3
- Operating System 17.2
- Frontend 20260325.6
