WiFi signal widget added to dashboard

A new widget has just been added to the emoncms dashboard which is useful for displaying signal strength - for example the signal strength from a radio device such as EmonTX.

This was originally requested by @Mark Derbyshire

To update your dashboard;
Emonpi’s - run the inbuilt update script
Self-Builds - run $git pull from within your emoncms/Modules/dashboard directory

Many thanks to @vkylamba for developing & submitting.



Thanks for this. I shall try it out as soon as I can :smile:
