Hi,
my sensors are conected in star topology, with 5 V supply from arduino. There is a single 5V supply from arduino for all sensors, the 5 V are connected to every sensor and no sensor is running in parasite mode.
The maximum length of wire i am using is about 8 meter to measure the outside temperature.
All other wires are ~ 2 meter long. Thanks for the guidelines, I will check my network setup.
My cables are twisted 0.5 mm cables without shielding.

The SW error did not occure during the weekend, I am still waiting to check if my reset works.
thanks,
