Smart Switch

Install

1. Setup static dev device Ref: linux - How to bind USB device under a static name? - Unix & Linux Stack Exch…

   Plugin your arduino smart switch

   Find out your device info (assuming it’s on /dev/ttyUSB0 at the moment).

   udevadm info -a -p  $(udevadm info -q path -n /dev/ttyUSB0)
       

   Enter a rule in /lib/udev/rules.d/60-persistent-iot.rules

   ACTION=="add", ATTRS{idVendor}=="1d6b", ATTRS{idProduct}=="0002", SYMLINK+="smart_switch"
       

   (Change 1d6b and 0002 with your idVendor and idProduct)

   Now replug in your smart switch and it should have a symlink as /dev/smart_switch. This is what is used in this program.

2. Add your user to dialout group Edit the /etc/group and add your user then relogin.
3. Start rails server

   rails s -b 10.1.1.10
       

Setup shortcuts

On my remote I’ve setup in Flirc.tv the shortcuts

Ctrl + Super + c = computer (tv + amp) Ctrl + Super + l = light

Shortcuts

Light toggle

curl http://10.1.1.10:3000/buttons/3/toggle

TV toggle

curl http://10.1.1.10:3000/buttons/2/toggle

I use the package ‘xbindkeys’ to set the shortcuts and then I can control it with the remote

Add the following to ~/.xbindkeysrc

“curl http://10.1.1.10:3000/buttons/2/toggle” Control+Mod4 + c

“curl http://10.1.1.10:3000/buttons/3/toggle” Control+Mod4 + l

This depends on what windows manager you use. I’m using LXQT on my media center.

LXQt -> Preferences -> LXQt Settings -> Session Settings.

In here you can add more autostart items such as;

xbindkeys
cd ~/code/smart_switch;rails s -b 10.1.1.10
