Thanks for the reply! I just put the transmitter closer to the display
(it was borderline to the wireless distance range) and the COM error
It's strange because the COM issue should concern only the PC and the
monitor, not the sensor/transmitter. In any case, just to let you know
that this solved the issue.
Yellowpark also told me to:
"manually select your com port: Settings -> Manually Select Comm Port"
However, in the CurrentCost software version v220.127.116.11 there is no
such option. I'm not aware of any newer version.
