Heya, I am also having no luck with 438K - I have tried both 438 and 438E options to no avail. Multiple restarts of HA & device, uninstalling and reinstalling integrations, etc - still no luck. @shenxn are you able to add compatibility for 438K models? my log:

I am having the same problem with the 438K. I guess this is a new version of the Dyson Purifier Cool Formaldehyde TP09? I have another machine with a "438E" device type, which is working perfectly.

Are you able to add support for the new 438K @shenxn? Thanks in advance.

[niemtec]

@mattdevo1 having exactly the same issue here. 438E added fine but 438K did not 😢

[BeHappy2021]

Same issue for me.

[niemtec]

I found this workaround to work. However, it's annoying given that it won't report the formaldehyde values thinking it's a whole different version of the fan. Does work though if that doesn't bother you.

[BeHappy2021]

Excellent find. @niemtec. I didn't uninstall the integration though. I just made the edit to manifest.json and restarted HA and it worked. I've got all the same values on the purifier cool as I get from my pure cool formaldehyde.

Excellent find. @niemtec. I didn't uninstall the integration though. I just made the edit to manifest.json and restarted HA and it worked. I've got all the same values on the purifier cool as I get from my pure cool formaldehyde.

Thank you!! This worked for me too (I didn't uninstall the integration either, just edited the manifest.json and restarted HA like you suggested).

I just realized also that I was never getting formaldehyde values from my 438E anyway. My primary goal was to automate on/of/speed etc. versus monitoring air quality, so this hack works fine for me.

Would be nice to get official support, but this will work for now.

No workaround to get formaldehyde values then? My device is listed as 438E. It's the pure cool formal fan TP09.

Unfortunately similar issue here as well. Model TP09 which is formaldehyde. get_devices.py shows me model 438K. When adding manually throw local, I will all required with formaldehyde option and error occurs. When I chose the Cool Pure then it was able to add the device (lot of functions are missing).
I changed manifest but only in the local version.
