Cannot import name 'DysonPurifierHumidifyCoolFormaldehyde' from 'libdyson'

[erd82]

As mentioned in a former post, my dyson integration sometimes appears as "not loaded" and then the dyson fan cannot be controlled anymore in HA.

These logs for dyson_cloud are showing these error messages:

The same appears sfor dyson_local:

How to get rid of this problem?

[danvy]

I've got the exact same error

[Ulrar]

That's intermittent?
It looks like it may be loading an outdated version of libdyson for some reason. Have you tried deleting it and re-adding it ?

yes, many times

I have the same issue. I have dyson cloud and dyson local both loaded and use my cloud credentials to use dyson local.

Here is the exact error I get

I've seen the same issue on my installation (done about an hour ago)

[Ulrar]

Can you check which version of libdyson is installed ?
Looks like you'd find it here : /usr/local/lib/python3.10/site-packages/

In my case I have libdyson-0.8.11 in there

[micahqcade]

It was 8.11, I removed the integration from HACS, both local and cloud, reloaded it and it now works. I think this is an intermittent problem, somehow the library either doesn't load at runtime or gets lost. To add, the initial installation worked, then somehow broke, and after I deleted and reloaded everything a few times, worked properly.

[erd82]

• Dyson cloud never worked for me!
• python3 get_devices.py also never worked > libdyson.exceptions.DysonInvalidAuth

I found a solution for me now: #178. Maybe it also helps others.

Unfortunately this integration is no longer maintained, but I've created a new fork and am actively working on the new Formaldehyde models.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.
