Finally got updated to 000112 last night and the plugin is now working as expected with my D201. I have observed one unexpected changed after the update. Previously the Doorbird would send a n http motion event on any motion, even in the masked area. Now, the motion events are only sent if the motion is in the unmasked area. This is the same as the cloud recording behavior. I suppose it is better to be consistent, but, it was nice to be able to do both.
Also, while I will be killing the DoorBird server app, at the moment it is still running and I have observed the plugin and the server both receive the same events at precisely the same time (Well, ok, within 1ms).
Nice work Pete.
