I've ordered a doorbell button to go with it. (arrived)
There's probably a "good reason" to connect this to the internet too.
This is somewhat related to #144
Well you've already got something but they were in with the alarms you can add as many doorbells and chimes and those have strobe flashes in case something loud is happening when someone presses a bell if any of that is any use
This is done, though if I'd have read @jamieisboss comment first, it would have been a more fun one!
