I created a new device at power.sixfab.com and completed the curl command using copy/paste onto my RPi4 with the PowerHAT installed. Everything worked with no errors, and the RPi has internet connectivity via ethernet, yet it never shows up as connected under devices at power.sixfab.com.
What can I do to troubleshoot?

Further: Iām trying to update the firmware manually since I canāt get an online connection. When I plug in power with S1 and S2 held down, the L1 light never goes magenta. Have I just got a bad board?

Hi @james.mcpherson,
Could you share the logs of the pms_agent service?
You could use: journalctl -u pms_agent.service
Sure, where are they? I looked through all your documentation and canāt find them mentioned.
As an update, I strangely got the manual firmware to work.
I did it by NOT pressing S1 and S2 on power up. I got the read_sensors.py example to work by pip3 installing the power api software, then running read_sensorsā¦ oddly I have to reinstall the power-api software via pip everytime I rebootā¦
However, after successfully getting read_sensors to work, I then tried update_firmware.py and it too worked. It went all the way through the percentages and reported that version 0.3.0 was successful.
Either something weird is going on with my board, or your documentation is waaay off.

Thanks for the edit with logging instructions. Here is the result of the journalctl command

As an update, I uninstalled, then created a new device in the web portal then reinstalled using copy/paste with exactly the same results.
I am able to control the UPS HAT with the python API so I know the mcu is working correctly.

I canāt post again because Iām too newā¦ however I fixed it.
I use a different user name than āpiā. The service assumes the āpiā user. I changed the service in /etc/systemd/system/pms_agent.service to my user name and added my group name and viola, it all worked.
