Hi Jan, Many thanks for your words of wisdom, I will take them on board. You say that the DS2482-800 can reset to an unusable state, would the same apply to the DS2482-100?  Sheepwalk now make a dual channel RPi2 and I could stack 2 to get 4 channels and I think I could manage with that if

I have a Pi with Sheepwalk RPi3 adapter running multiple temperature and I/O.  I get random read failures and bus lock up, read failures every day or two, bus lock up every week or so. Currently I have separate power supplies (Meanwell units) for the Pi and the 1-wire and they are both
