Energy Management in Home Assistant

[beccsjb]

The only option i have on the recorder in confi yaml is auto purge. Otherwise everything else is stored

`recorder:

purge_keep_days: 14`

[OzGav]

Not sure what effect that minmal config will have. Mine is:

recorder:
  purge_keep_days: 5
  db_url: mysql://secretlogin:[email protected]:3306/hadata?charset=utf8mb4
  commit_interval: 300
  include:
    domains:
      - sensor
      - automation

I’ve tried using something more similar to yours, though storing alot more data.

it’s being pushed to a 108TB raid array so data isnt to much of a concern, especially while testing. Id rather grab more and not need it etc.

Still havnt seen a change though…

See image which i think is strange, cant really find much of a definition for it though. Its like its seeing that theres data there though, just cant do anything with it for some reason.

But: The sensor value is increasing during the day and stays on a final daily value once the sun sets - the value of the sensor now stays on that value until the next morning once the inverter is powered on again (and then starts from 0),

Hmm, does it stay at the value once the sun sets or actually become unavailable? Maybe you can use a template sensor to zero the reading when the sensor becomes unavailable.

I configured my Fronius inverter to stay on even when there’s no solar so that the metering keeps working.

Give it a couple of hours and see what happens

There is a bug with the default Riemann integration method (“trapezoidal”) that could be responsible for that kWh difference/error. Have a look here, and vote if it is your case:

Riemann integral calculates wrong values with electrical devices

The riemann integral is used to calculate for example the energy comsumption from the current consumption. Or if a sensor delivers “liters per second”, the riemann integral calculates “total liters”. The riemann integral integration uses the trapezoidal method as the default calculation method for the area under a curve. But in in many cases this default is wrong. Assume the temperature curve of a heating radiator which is polled every 10 minutes. If it is 20° at time t and 30° at time t+5, …

Not a bug, a misconfiguration, as described in the thread you linked.

How to track the consumption for exact from/to period? My electricity invoice has from to which is 15th of the month to next 15th of the month?

[OzGav]

I think you need to use a utility meter with a 15 day offset Utility Meter - Home Assistant

Really great to see you working on a Victron integration ! I’m putting my hand up to be a beta tester when you are ready

Hi I have 2 sites, 2 electricity subscriptions. I run both my sites off one HA and its not clear how to configure the new energy management for this situation. I can add both consumption sensors easy enough but then I get one dashboard with both and I’d rather have 2 completely separate dashboards, one for each location.

Is it possible?

Thx

Jeremy

Hi, I didn’t see “energy” in the sidebar. What do I need to do to view it and add a device? It is not mentioned anywhere on the Internet.
I have core-2021.9.6 and 6.2.

Thank you

In configuration.yaml you need either

default_config:

or

energy:

It’s mentioned multiple times in this thread, even multiple times by me alone…

[casadelnaranco]

I hace a problem configuring battery. The Energy coming ni/out of the battery doesn’t initialize everyday and ni the visualization, it shows the energy in/out of the day before.

The error is in the first pink bar and in the first light blue bar.
How can I solve it?

[OzGav]

Have a look here where I posted one solution to this general problem Energy Management in Home Assistant - #891 by OzGav

[nswe (Nick)]

Is it possible to use this somehow to see your current energy consumption and history but for regular devices like hue lights, TV devices etc…

Similar to how it works in homey.

Powercalc - Virtual power sensors

In the last few weeks I have been working on a custom component to get virtual power sensors for your lights or other devices. It is stable enough right now to share it on this forum and make dedicated topic for it. The component provides multiple strategies to calculate estimated power consumption. One of the most interesting is the LUT method (using lookup tables). Some community members and me have taken measurements for all kind of different brightness/hue/saturation settings and their resp…

Hi
very nice feature, but on my hassio it seems to be a bit random. I’ve integrated a few of my Tuya SmartPlugs and my UPS (CP1500EPFCLCD by CPS), but the UPS graphs are showing funny data. I have a pretty much unchanged use of my computer (I know, I shoud get out more…), and the energy meters show some pretty random data. It should show about the same consumption for the last 3 months, but it doesn’t. Even the costs are calculated wrong, it shows a bigger sum on lower consumption, see pics.

in July it shows 50kWh/0€, August 108kWh/12€ and september 90kWh/21€

Hi,

Would anyone know how I would write a gauge or data set to record my highest KW usage for my house between a certain time.

For example my utility provider changes me what they call a demand change, this change is a set fee .50c multiplied by my highest usage for the month for between the hours of 5pm and 8pm. I have the data just note sure how I could do it for example

Highest usage for July between those house was on 20th and it was 8kws.

Any help would be appreciated.
