HomeKit Siri failing to complete HomeKit requests

[TonyC28]

I’ve been having an issue that seems to be getting worse. Focusing on the most problematic device, when I tell Siri via my Apple Watch to open my garage door (using MyQ), it most often fails. I’ll get a “device was slow to respond” response. If I pull out my phone and hit the button in Control Center, the door opens nearly instantly. Today, I tried initiating the verbal command from my iPhone and got the same failure. And again, the button works instantly. I’ve reported this to Apple but I’m wondering if anyone has seen similar behavior. Why is Siri failing to deliver the command?

I see this occasionally too, only suggestion I have is reboot router, devices, and home hubs
