Kobalt:

You can control it if you build something like this:

Easiest is probably using some sort of Bluetooth relay that is being controlled manually by your smart phone or via GPS in your smart phone. 

Thanks . It looks interesting, but a bit complicated for me .. and I want the valve open, not closed Smiley  I would like to just pull  a fuse, hose , cable to have the valves open all the time .... like it was on the older models .

If I understand well , I could pull the PSE Solenoid valve plug and then it is open all the time ?
