I’m not sure where to start as it used to work before I did the upgrade from the Admin panel.
Help and advice pleas!

ok
With more googleing it seems I need
python3-configobj
python3-serial

I wonder why they weren’t there? If anyone else has this issue, you need to run
sudo apt-get install python3-serial python3-configobj

and a reboot brings it back to life…So far, anyway!

Python3 for emonhub emonHub

emonPi/base update now includes updating emonhub to python3! The update process includes the installation of Python3 and dependencies as well as a call to apt-get update which can take a little time on slower connections. The emonPiLCD script and service-runner are still ran with Python 2.7 which remains on the system. Thanks @bwduncan and @borpin for all of your help with this!

The update is moving to Python3 but should run the install script which includes

github.com

openenergymonitor/emonhub/blob/da27a4aa68be47aafcb4ffe843ad09f9f450d481/install.sh#L19-L19

    
      
          sudo apt-get install -y python3-serial python3-configobj python3-pip

Could you possibly post the update log plus the system info from the Admin panel please?

It will help us identify what the issue might be.

The solution will be to run the install manually

cd /opt/openenergymonitor/emonhub
./install

just say no to question (key input is not echoed; just hit return).
