Oh I get it! So spend a load of money on something that does the same thing as a valve or tap. Add some weight to the pole. Reach in your pocket for the key fob every time you want to use it , change batteries when it goes flat etc.
Brilliant! I want one.
Except I'd need three - one for every pole.
