Battery not working

[elRadix]

I added both sensor but nothing is happening, those are the sensor that used in the energy consumption and both are in kWh. Both are created from a template sensor coming from an utility meter as basis. I am using a P1 meter to collect the data. see below config and screenshot

Exactly the same issue... It is in my case indicating correctly if the battery should charge or discharge but the curve is definitely flat at zero...

[hif2k1]

Well I'm really glad people are interested in my extension! Thank you for the feedback. I'm guessing it's something to do with the sensor data maybe. Can you post any of the meter readings? How often are the readings from the utility meter, are the positive or negative? Are they in kwh?

[elRadix]

yes they are both getting real time updates and are both positive

export sensor

import sensor

[hif2k1]

Ok, I'll have a think.

[hif2k1]

I think I might have fixed the bug. Can you update the integration and try again? If it's still not working then let me know. Thanks.

[elRadix]

Ok, I'll let you know tomorrow when the sun is back.

This is a great project by the way, but i had to make a few Tweaks the sensor/py to get things to register and they may relevant to the above.

My Import/Export is live (second-by-second) kWh and noticed that the battery would charge/discharge well when there was large amounts of Energy moving. But the slight overnight discharge or when the generation was near equal to consumption was not being registered.

I increased the Float for the round from 2 up to 10 digits and now the Battery discharges at a much better rate.

[RalfPfitzner]

(Almost) No discharge over night was the same thing that occured to my installation as well.

Well test with the new rounding setting from NBS 1997.

[Yorik-Code]

Similar here, came here to post something similar. Even took screenshots to see if it will help. I will also test now.

[Yorik-Code]

With these changes, mine is now working as expected. It is creating some very long outputs in terms of decimal places, but it is working nicely.

This is a different issue so I've opened a new issue for this and tried to implement a fix

[elRadix]

with the latest update, the battery is now working

@elRadix : stupid question but how do you make a card with the attributes visible like in your first post?

[hif2k1]

I don't think that's a card, I think it's the entity view. If you go to configuration, entities and find the entity on the list and then click the sliders button in the top right. You can then expand the attributes section at the bottom.

[elRadix]

you can this card

  type: custom:entity-attributes-card
  title: LG Battery 16KW
  heading_name: List
  heading_state: States
  filter:
    include:

Can you give more insight in how you did create this sensors and screenshot how you implemented this in Energy Management? I rather novice in writing yaml.

[hif2k1]

I've now added charging and discharging rates and daily energy counter to the attributes. I hope this will make this a bit simpler. Thinking about adding them as separate sensors rather than just attributes as well. What do you think?

[TheGreatHorla]

@hif2k1 : In my opinion it would be easier to have almost all the attributes as another sensor. I (and I imagine most of the users) use it to see if a home battery is a usefull investment (in the winter the answer is no for me it seems unless I expand my solar panels greatly). I used Elradix template to view all attributes because only the battery percentage is fairly useless. I would be easier for users from HA like me who doesn't write complicated automatisations but just use a couple of integrations and expect it to 'just' work.

In answer to this question, this is what I have setup to get this working. Note that the attributes now include a "daily energy saved" so most likely you could use that instead of setting up a daily/monthly utility meter, but I have done it this way as I adapted it from the old method.

You'll have to specify your own sensor for the input data, mine being sensor.tesla_powerwall so just replace my instances of that with whatever your own battery shows up as.

Yes please.

Different sensors would make it a lot simpler to utilise.

Sensors that can feed the energy dashboard directly would be ideal.

Fully agree with that. My goal is to test the simulation for a longer period to determine if the ROI is feasible.

[hif2k1]

OK, thanks. I'm just testing a release of multiple sensors/entities. Had a few bugs, but should be ready soon.

Latest release has individual sensors for most attributes. Haven't got one for money saved yet because I need to figure out how to handle the units, but will try to do this too.

To explain myself I doubt that it’s feasible to invest in a LG Chem battery infrastructure. Measurement and simulation can help me to determine the feasibility. So I only need to know the amounts of kWh I can save on one year.
