About

This is a LIRC Adapter for the Mozilla IoT Gateway, made to work with my very specific hardware setup.

Unfortunately, it's not quite install and go - you'll have to do some work to get everything running on your own gateway, but I've tried to lead the way as much as possible.

Features

• Automatically list each available remote config as a device that can be added to the Gateway.
• Set up each command as a button.
• And if you've got the time and patience, you can override this default functionality with an extension.

Prerequisites (AKA my specific setup)

• A Raspberry Pi running Mozilla's Web of Things Gateway. Instructions here.
• An Infrared Shield. I use the one that looks like this, because I'm not a wizard. If you are a wizard, you could probably just plug an IR LED straight into the GPIO pins.
• LIRC installed and configured on the Pi. Github user prasanthj has written some awesome instructions.
• At least one remote control configured. If you can manually run a command like irsend SEND_ONCE <device-name> KEY_POWER then you're good to go.
• SSH access to the gateway. You should be able to switch this on through the Gateway interface under Settings > Developer. The Mozilla wiki has more info if necessary.

Build & Testing Process

I haven't yet figured out how to properly package this as an addon, so here's what I do to install and test it.

1. On the Raspberry Pi (SSHd into the Pi, Browsed to ~):

• (Optional) rm -rf ~/.mozilla-iot/log
• rm -rf ~/.mozilla-iot/addons/lirc-adapter/

2. Switch to Dev machine (Browsed to project folder):

• ./package.sh
• scp -r . pi@gateway.local:~/.mozilla-iot/addons/lirc-adapter

3. Switch back to Pi

• sudo systemctl restart mozilla-iot-gateway.service

4. Wait a reasonable amount of time for the gateway to restart
5. View logs if necessary

• (cd ~/.mozilla-iot/log && cat "$(ls -1rt | tail -n1)")

Thanks

• Mozilla for the gateway and example addons.
  • The Wake On Lan Adapter was the most useful example for starting out
  • The Node Addon Code was a great reference for figuring out what the heck is property and how do I parameter it.
  • The Schema Let me know what my options were.
• hobbyquaker for the NodeJS LIRC client which is one less thing I have to figure out myself.
• prasanthj for saving my sanity when starting out with LIRC.
