Just got a sensor failure message on the new sensor. I don’t understand what I could be doing wrong! It is really pretty simple. I powered it off and will see if turning it back on helps. I saw some replies that the failure warning is not necessarily accurate.
Just replied on other posting, but also make sure the transmitter is securely snapped in both sides. Pinch it with your fingers to make sure. Try again in the morning - let it wet overnight. Leave everything in and the transmitter snapped in and the receiver close by. I do way better with mine if I insert at bedtime, and start in the am - even with the G4 - otherwise I tend to get a lot of weird readings the first day.
