Hi,
I build a openZmeter three phase device V2.02 last year and I am happily using it with an isolation at a Raspberry Pi. It works very nicely since then.
Recently I wanted to build a device for another lab, but ran into unexpected problems.
The new device is flashed with the same firmware as the other one and gets recognized by the computer:
[...]
kernel: usb 1-1.1: new full-speed USB device number 19 using dwc_otg
kernel: usb 1-1.1: New USB device found, idVendor=0483, idProduct=7270, bcdDevice= 2.01

When OZM is started it also recognizes the device:

In the webinterface the analyser can be set up and configured. However the dot in the Analyzers tab turns from yellow to red shortly after and everything is offline. No data seems to be going in but there are no errors. I am not sure how to debug this further.
How could I investigate this? Why would the analyser be red?
Could the device be bad? Has it to do with the serial number?
Thanks in advance!
