1wire sensor not giving values...
Hi, my tenperature sensors connected to Unipi 1.1 suddenly stopped giving temperatures.
I have not done any hardware changes, just rebooted Pi several times and I was doing some "cleaning" of the Pi /apt-get autoremove etc. / ---- could that be a reason ???
evok.py is telling this - is this usual or does this mean there is a problem somewhere ?

It's possible - do you have OWFS installed still? It could be caused by a faulty sensor as well, try plugging them in one by one.
