Thanks, now it works OK. I was checking because previously if I set the GPIO to anything other than "None" it bricked the board and I had to reflash it to recover.
An update, I've checked and it works at both 5V (from the 433MHz connector) and 3V from the GPIO pins, in both cases it takes several minutes to first get a reading, so shows readings of 0 for awhile before it shows the actual values.
