Pete,
Many thanks for your work on developing this plugin.
By installing it from the Indigo Plugin Store, I was able to integrate out Doorbird D101 doorbell with Indigo 7.4 without any difficulty.
Now, whenever someone presses the doorbell's button, we also get a 1 second chime coming out of the Aeotec Siren 5 we already had installed in the back garden outside. A very nice addition for those situations when you're out in the garden without your iPhone.
Many thanks,
Cesar
