I was in the process of putting together a Raspberry Pi Zero W based Garage door controller. (I already have a Konnected board and love it, but can't afford $80 for just the board) with wired switches for Fully Open/Fully Closed Positions.
I can buy this Pi Zero W with Case and Camera kit for $45.00 USD
I can add this Relay Board for $12.00 USD
I already own some wired switches like these
I can 3D Print a case for the relays, I already have a bunch of power supplies and all the required cables and memory. I also plan on adding a temperature/humidity sensor to the board as well.
That's around $57 USD for the whole setup. I have additional situations for devices just like this, so I want to make it as modular as possible.
Eventually I will want to put a warning light and buzzer on the additional relays.
What is the easiest way to monitor Pi Based sensors from Hubitat?
Do I need to "pull down" the voltage with a resistor or something on the Door Sensors?
What Python module controls the Relays? Got any example code?
How do I view the camera through a dashboard? Remotely? Can you use the Pi Camera for motion detection and alerting?
