Not Getting Apple Watch Notifications From the Doorbell

I have a powered doorbell connected to my 2C camera system. I have an iPhone X with the latest IOS and an Apple Watch 4. I have all notifications active and all banner types.

The mobile gets doorbell notifications but the watch gets nothing. All settings for notifications are on to mirror my phone to the watch. I have restarted both. I have tried both having the mobile app running and not running in the background.

If my watch is not next to the mobile its at least on the same wifi network. I get all camera and door sensor notifications from the same Dufy app, but never a door bell one on my watch, which appear on the mobile

I have just changed over from a ring doorbell to Dufy to save monthly subsections, but unless my watch gets the notifications its kinda useless to me.

Please help.
