Any ideas?

Ive tried deleting the integrator and waiting…

Here’s the last of my logs:

The most probable thing is that the VT is not working. If you have a voltmeter, see if it is putting out 9-12VAC.

If you don’t have a voltmeter,
Remove any CT from input 14.
Configure it as a VT (same model as your input_0)
Plug the VT into the three-phase input 14 on the other end of the IotaWatt.
See if it appears as non-zero in the status display.

I finally got around to replacing the mp-3027 power supply for voltage readings.

Unfortunately it didn’t correct the issue.

My iotawatt is actually installed in a terrible location (behind my board) so I’m a bit stuck with plugging things in and out.

Any other thoughts or suggestions? Is there a hard reset option available?

Still looks like VT. Did you try testing the voltage and/or using a different voltage input as in the above post?

Hi Bob - sorry I misread your message.

I have done as instructed and can see voltage on input 14.

Ok, good. That tells me that your input 0 is not working. Most likely the jack has detached from one or more of the PCB pads. That is easy to fix if you know how, but probably not necessary. You can use the input 14. If you go to the inputs setup for each of your inputs you should now see a new parameter VREF that should look something like this:

Change it to Input_14 for each of your inputs and everything should work.

Thanks Bob - wish I’d listened to you from the start instead of stubbornly blaming the input device.

That’s done the trick.
