Hi guys,
I have a Shelly 3M device which I use to measure the consumption of two different circuits. The device is connected to the cloud, and I can see the real-time consumption of both circuits without any issues. However, in the Charts tab of the app, I can't see any graphs. It only shows "No data available!" I've reset it to factory settings several times and also waited several hours between resets.
What could be the issue? 
By the way, only happens in this device, I have anothers working well (no 3M)
Thanks!
