Cannot Import Name 'DysonPurifierHumidifyCoolFormaldehyde'

[shukarCA]

I have recently installed both the Dyson_local and Dyson_cloud integrations on my HASS OS VM, and they were working great until the system rebooted. Now they are both failing to load and giving the following error in the logs:

Setup failed for custom integration dyson_cloud: Unable to import component: cannot import name 'DysonPurifierHumidifyCoolFormaldehyde' from 'libdyson'(/usr/local/lib/python3.10/site-packages/libdyson/init.py`

I suspect this is related to my newer Dyson fan, an HP07 Purify Hot+Cool, since I had zero issues previously with my older two Pure Cool Link fans.

Please advise on any additional logs or information required and I can provide as needed.

I'm having the same issue and no changes to my previously working fan setup, so don't believe this is related to your new Dyson model.

Probably worth checking which libdyson version(s) you have in your HA. At least some time back Dyson cloud installed older libdyson than Dyson local. See https://github.com/shenxn/ha-dyson/issues/103#issuecomment-1093901557

Thanks, @GitPetri. I was able to install both local and cloud.

I have modified manifest.json

libdyson==0.8.11 originally it was 0.8.7 I think now it matches the version of local.

However, got another obstacle. Local was able to pull all information from the cloud, however, when I try to configure local it asks me for the host (I know this should be ignored) and when I press submit I got an unknown error occurred.

In the logs, I have found below.

This error originated from a custom integration.

Same issue here

Unfortunately this integration is no longer maintained, but I've created a new fork and am actively working on the new Formaldehyde models. Have a look at #185 for more information, and let me know if you have any questions.
