I installed an Emporia Vue 2 a few weeks ago and have turned to my Home Assistant for monitoring. I’ve installed InfluxDb and Grafana and made an effort to just track total energy used. See the following screenshot:
There are weird spikes every 12 minutes after the hour. I can’t track these down anywhere. None of my circuits show the spikes so I’m assuming it’s a data error of some sort. Any thoughts? Does it have anything to do with how I have it setup?
These spikes are generally produced by Freezers, make sure if your freezer has an inverter compressor. More specifically, for old compressors these spikes correspond to the compression phase where the compressor needs its maximum power. You can try to monitor the freezer individually.
Great thought. I have been monitoring that circuit and there’s nothing like this on it. And the fact that those spikes are EXACTLY one hour apart (to the second) makes me think that it can’t be an actual circuit.
My freezer does a defrost cycle every hour. If you have a freezer, unplug it shortly before you would expect a spike to see if that is the cause.
Also, please let us know what you find.
Ahh, that’s a great idea. I’ll keep you posted.
Notwithstanding the other comments, the graph doesn’t look right. The raw data for energy should constantly increase (until reset), whereas power fluctuates as devices consume electricity. And 115kWh is having a 115W device constantly using power for 1000 hours. What do you see in the HA graphs for the entity?
I think the issue is there is no “WHERE” defined, so it’s possibly giving you a 1 minute mean of all entities with “kWh” units. How else does it know which entity to work on? I assume you’re using this integration, which according to this gives 1 min, 1 hour and 1 month entities - so maybe during the minute that the 1 day/month entity data updates, the mean of all is therefore much higher.
With Grafana I would expect something like this:
Obviously, changing the entity to one of the energy monitors rather than my weight.
Okay, I think you may have found it. I’m new to Grafana so still figuring a lot out. When I first selected KwH as the measurement I’m looking for, the graph just appeared so I mistakenly thought it was measuring the total energy output for some reason. When I select the Vue home sensor, I get something much more rational looking:
Except for that weird dip at the end of the day, I would think this is what I should be seeing. The Vue sensors have 1 min, 1 day and 1 month sensors but for some reason, Grafana only sees the 1 day and 1 month sensors in entity so I’ll need to figure that out. I’m guessing choosing the 1 minute sensor would give me more accurate, or detailed, results.
