I've two screens attached to my main computer. I prefer to put it to sleep rather than shut it down every day , so I have to shutdown both screens everey evening, and turn them up every morning. As I am lazy, I've designed this node, to be able to either manually turn them on/off, or better, to automatically turn them off/on whenever the computer goes to sleep or wake up.

As always when adding a node into a room, I've also integrated a sensor to report the romm's temperature, instead of building a separate one.

This MySensors node provides the following features :

• Controls a Device state (On/Off) using a Relay
• Switch the Device state via Radio (MySensors)
• Toggle the Device state using a single push button
• Feedback the device state using 2 leds (Green and Red)
• also reports Room temperature every minutes
• recovers the last state when powering up
• blinks the green led while sending the temperature
• blinks the red led while receiving a relay command

On the Mac, I'm using the SleepWatcher script to trigger a mysensor command, fetching an 'action' URL from phpMydomo, whenever the Mac is going to sleep or to wakeUp. The 2 triggered scripts are as simple as:

on WakeUp :

wget http://IP_OF_MY_PHPMYDOMO/action?type=mysensors&preset=monitors_on

on Sleep :

wget http://IP_OF_MY_PHPMYDOMO/action?type=mysensors&preset=monitors_off

You would certainly find a equivalent solution on windows on Windows or Linux to trigger a script upon Sleep/WakeUp.

For simplicity, the radio module wiring is not described there. Please refer to this MySensors Page to learn how to conect the radio module.
