I am using Indigo 2
I tried first to unplug then replace the sensor
this did not work
the only operation that did was to pull the power from
the EZIOSA and 8T then re-sync them with the Indigo
software and set them up for one wire temp status.
the readings I would receive were 0 or 255
The rest of the communications for the units seemed to be working
thru out this failure.
