The other day I had the watt hours drop by about half for no reason I can explain. The watts didn’t change. Event happened around 11am. Around that time I had updated home assistant and the machine I run it on. Figured it was an issue there, but when I looked in my IoTaWatt to confirm the data I also saw the drop there. What should I be checking to figure out how to fix the data?
Is Mains an output or integrator? Can I see where it is defined?
Mains is an output
Puzzling. Can you show that graph with the statistics tab exposed please?
Can you post the message log please?
Think I figured it out. The emoncms instance I had setup on my homeassistant machine didn’t fully come back up after the reboot. It’s redis server didn’t start up and emoncms is throwing php errors. I deleted the emoncms uploader config and the IoTaWatt stopped rebooting.
Here’s yesterdays graph with statistics.
Here’s after I turned off the emoncms uploader
Looks like somewhere in the uploader the error response from emoncms is causing issues.
That appears to be the problem. If you set the low Y axis for Watts to zero the two should lie right over each other,
The PHP errors in Emoncms causing restarts is a relatively new issue. The error response is a large HTML file and is using up available memory. I’m looking into a way to bulletproof, but in the meantime you need to avoid those errors in Emoncms.
I’m just going to drop emoncms. It was a pain to get setup and I didn’t even have it fully setup. Was going to use it to aggregate the data from my IoTaWatt and solar system, but I think I’ll just do that in homeassistant.
Here’s the error response I get from emoncms if it’s of any help debugging. Let me know if there’s any data that I can pull that would be of use.

If you can get the solar output into the IoTaWatt, I think you can do everything with Graph+.
