<![CDATA[Omega2 Pro - can I detect main power/switch to battery programatically?]]>I'm running my Omega2 pro via a 5v USB feed at the moment, and there's a LiPo battery also plugged in for backup. If I disconnect the main power it switches over just fine but what I want to do is to be able to detect that this (and vice versa) when it returns.

Is there any way I can do this via software, preferably with Python(3) as I want to be able to raise a notification?

Any takers? I'm keen to know as I did a battery test yesterday and achieved just over 12 hours with a 3000mAh LiPo battery. Initially the Omega was just idling, but then I set up a wget my homepage in a loop to give it some exercise. Very impressive.

If I can query it programatically I can then either shut it down gracefully or get the proxy to divert.

I will have a poke around the power-dock-2 script and see if i can figure something out from that.
