I’ve recently resurrected an old emonPi with a new SD card from the OEM shop.  
Inputs and Feeds are showing up as Null.  
Log looks as follows: (Lots of not authenticated - but not sure what this means)  
All of my services are running and are Green

Hello @goldfish do you see any activity in the EmonHub log? (Available via the main emoncms setup menu) Data is initially read from the emonPi energy monitoring board using EmonHub before it is then forwarded to the emoncms installation. It may be getting stuck at that stage… alternatively it may be worth using Admin \> Update to update the firmware on the emonPi to see if that brings it back to life…

e.g:

Hi Trystan  
Success - looks like the firmware update solved it. Getting my main and solar inputs and have logged to feeds.  
Thanks
