This repo contains my Arduino homeauto sensor sketches, notes, etc which make up the sensor array part of the home auto project.
Sensors interface with homeassistant via a MySensors gateway node.
I turned this old rotary-style (but keypad operated) phone into a multi-controller for the house, to control lighting scenes, alarm system, thermostat etc. I also implemented a child-lock; when the receiver isn't in the cradle it doesn't send commands.
See it in action here.
An Arduino board hooked up to a metal object serves as a touch switch for the bedroom light. This sketch sends a signal to the homeserver whenever this singing bowl is touched:
A temperature & humidity sensor (DHT22) for the greenhouse to monitor conditions for tomatoes. Battery operated, low power. Homeassistant warns when temp or humidity leave acceptable range.
Security sensor for the garage incorporating:
- motion
- sound
- door (open/close)
I had to manually debounce the motion detector because occasionally a spider wanders over the sensor.
Alarm signal is passed to homeassistant which raises the alarm via mobile notification and Sonos speakers in the house.
Also has a temp/humidity sensor too - because why not?
