I’m just planning an order to place soon with the fever discounts. I am thinking of getting the Energenie board to control two sockets, and then a Skywriter / Skywriter HAT with which to control them. Obviously, you can’t stack two boards on the pi at once, so I was wondering if it was possible to fudge it at all. I can find from their documentation which pins the Energenie uses, and I was wondering which pins the Skywriter HAT uses so that I could see if I can use them together. I looked in the python examples on Github, but it was a bit hex-ey and confusing! The Skywriter no-HAT looks like it uses SDL/SCA (no compatibility issues here), and also something called TRFR, and I don’t know what that’s hooked up to on the HAT (and I’m assuming that they’ve got the same pinout here).
Secondly, the Skywriter HAT product page claims that it ‘Senses from up to 5cm away!’, but the Skywriter no-HAT says that it ‘Senses from up to 15cm away!’. I was under the impression that they were more or less the same thing, so why is it that one has a measuring distance three times that of the other?
One last question:
With the promotion, 10% off and a free RasPi for over £99, is the £99 the price of the order including the 10% discount, or after it? In other words, if I place an order for £100 worth of stuff, then get a 10% discount (ie I pay you £90), do I still get a free pi 2? Sorry if that’s confused you as much as it did me typing it!
