# RealFakeGarageDoors

Garage Door Opener for ESP8266 / Arduino.

This is the hardware portion of my Real Fake Garage Doors project.

The client is the [homebridge-real-fake-garage-doors](https://github.com/plasticrake/homebridge-real-fake-garage-doors) plugin for [Homebridge](https://github.com/nfarina/homebridge).

I opened a [Linear Multi-Code 412001](https://www.amazon.com/dp/B000F5KEP6/) garage door remote and attached an ESP8266 to trigger it to open the garage door. Since the ESP8266 doesn't have an easy way to encrypt traffic as a server I'm using SHA256-HMAC to send authenticated commands to the ESP8266.

## Configuration

`HASH_KEY`: SHA256-HMAC key that should match the key from homebridge-real-fake-garage-doors.

`MAX_OPEN_COUNT_PER_MINUTE` / `MAX_OPEN_COUNT_PER_HOUR` / `MAX_OPEN_COUNT_PER_DAY`: If any of these thresholds are exceeded then the device will no longer fulfill any open commands until the device is reset. This is a safeguard against any errant clients continuously sending open commands.
