Type 438K Fails to Connect

[niemtec]

I keep getting "Failed to connect" when trying to add one of my Dyson Formaldehyde fans. Strangely, one of them (Type 438E) connects fine pretty instantly, however the second (Type 438K) results in "Failed to Connect".

Any ideas why the minor type difference would result in a failure?

Have the same issue Device Type: 438K, previous mode 438E connected fine. with 438K I tried device ip in host and connection in the dyson app but no luck.

So turns out that libdyson contains a bunch of mappings which relate the fan type to its number. 438E exists in there as the formaldehyde one, but for some reason 438K does not despite being of the same type. I've added that note to the existing merge request, hoping that the owner will address the issue.

Unfortunately this integration is no longer maintained, but I've created a new fork and am actively working on the new Formaldehyde models.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