I just built a (proof-of-concept) door bell, which talks MQTT (via fixed Ethernet), mainly, because the door bell is at the gate 80m from the house.
I could be in the shed, or later in the house, and was wondering what method(s) to use to notify me that the door bell has rung.
The door bell already talks to OH, the question is now, what do I do with the signal.
We are next to a computer quite a lot depending on the time of day.
We may be out on the property.
I thought of:
a) using the presence detection to issue an audio message (either spoken text or door bell chime sound)
b) surely a message on whatever sitemap (mostly useless)
c) yes, activate an actual chime
d) … ???
We do not carry smart phones due to zero reception; nor would we carry anything else (NFC, RFID, etc.) and also avoid wireless where possible (only on for an hour per day).
I understand that not carrying any device will make it difficult to get notified outdoors; however, I just thought of installing one of the old car horns which sound like a cow mooing.
Any ideas welcome. Thanks.
