Kumo Integration dropped all entities

[bsmontgomery1]

I had this working for about a week. I look today and see all the units are unavailable. I reloaded integration, reboot home assistant, etc. I then removed the integration and readded. Most of the time I get failed to initialize. Sometimes it pulls the devices in but they are always unavailable. I grabbed a very small log of some of the errors below. Note the kumo app works. The account and password i put in the config are correct.

Please let me know what you need from me to see what the issue is for fix.

"device_authentication_error" means it's not getting the required keys from the KumoCloud service. They could have been having an issue, or the KumoCloud account credentials you provided are not right. Or, if your devices are DHCP and you haven't pinned their addresses in your router, they could have shuffled around w/o KumoCloud catching up and it's got the wrong keys.

If you have any Python skills, i'd suggest using https://github.com/dlarrick/pykumo?tab=readme-ov-file#interactive-use to further diagnose.
