Mesh Connectivity LED

There’s a recently added issue on the Github project requesting the ability to display mesh connection status on an LED or other visual indicator.  I’ve been wanting to add such a feature for a while now, and today I had some time to knock it out.  I wrote a PHP script that retrieves the OLSRD neighbors list, checks them using ping, and then updates the color on a BlinkM module to indicate the number of active neighboring nodes.   Because the script is not directly related to HSMM-Pi, I placed it in a separate Github repository of its own: olsrd-blinkm

Here are a few photos showing the Blinkm in a green state (e.g. 2 or more active neighbors):
