Doorbell #16

I think adding a doorbell type would be great as in my example I use a 433MHz bushbutton which publishes it’s unique code of MQTT when pressed. This triggers an OpenHAB rule which sets a switch item to “ON” for a second then back to “OFF” (the same rule timestamps a datetime item so I know when it wasn’t last pressed).

From the HAP accessory description, it appears to be similar to a switch although probably will only trigger on the rising edge?

I’d love to hear your thoughts.

Thanks for all your great work!

Hi @danricho ,

there is a doorbell type defined by the HAP protocol, however the implementation is not trivial, since it requires a video feed, that is not supported by openHAB and therefore I decided against the implementation of this type in the context of this plugin.

The way you could implement it using the current features of this add-on is by declaring it as contact sensor, that can be set to send you notifications inside the Home.app. Unfortunately it will then send you notification when "ON" and "OFF" is received, but I don't see another way.

Regards,

Frank

I didn’t realise that the video stream was mandatory. I currently use a contact sensor for this, so that’s fine!

Thanks again
