Hi There is now 75 hours my script is running. I've got: -0 owread errors :-) -4 out of range errors Since today I've had a 8th device, a temp. sensor DS18S20 (the one that was disappearing some time ago) in 75 hours it approx 23000x7readings (8 readings since today) and all succeed! So it's not bad at all. Anyway I have to continue because the problem can happen after several days. Here are the out of range errors:

I guess I can deal with that by software filtering if I have so few. But again, caution, wait and see...
