If you add a new device and then remove it. After that you add another new device it probably get same Id. Clean EPROM and retry.

Serial Gateway mystery
I use Arduino Nano as serial gateway and after some initial problem it now works ok. I also have one node with two DS18B20 up and go.
The mystery is that I have a red banner saying "Can't Detect Device" beneath the MySensors Plugin description in Devices. Also in Dashboard I have a message "1 Device no longer connected".
I have try to delete the plugin and reinstall everything but with same result.
I use UI7.
Pls help, I don't want this allert.
