15.4 broke Siri commands for this plugin

[AdeTheux]

Homebridge v1.4 with Dyson plugin v2.7.3. Since I updated to iOS 15.4, when I use Siri to change the Dyson settings, I get a "uh oh there's a problem". In the Home app however, it appears to be working fine and I can interact with it, change fan speed etc.

Same, except when I tell her to turn the fan on, she says, "Okay, what switch?"

I can also report this issue. I don't know whether it is the plugin or a glitch on Apple's end that they haven't cared to fix yet.

I have also experienced that my automation to turn the fan on at a certain time always sets it to 100%. I can't change the configuration either. It really just seems like buggy Apple stuff in my opinion (but don't take my work for it).
