Home Energy Management in 2021.8

wmaker · August 9, 2021, 1:46am

I’ve made an energy template sensor with a last_reset attribute of ‘1970-01-01T00:00:00+00:00’ and have done a quick check to see that the Home Energy Management System sees this sensor in its list and it does!

However in reality, that meter actually resets at midnight. So I’m actually trying to figure out what the template for last_reset should look like. Any ideas?

EDIT/UPDATE:
What seems to work is the following:

last_reset: '{{ now().replace(hour=0).replace(minute=10).replace(second=0).replace(microsecond=0).isoformat() }}'

The meter I use does cloud polling so it actually does not get reset at midnight but some number of minutes after that. However, since it appears the Home Energy Management does an update around 12 minutes after the hour, I decided on minute=10, but again minute = 0 will probably work as well.

I have configured the cards, but I would like to view the consumption of the last 5 days at the same time without having to change the date.
Do you say it is possible?
alternatively, can I put 5 sensors that take the data from the home assistant db or from a csv file that saves me the total consumption every night?

I am trying to configure the Energy configuration. I have a ‘Used’ Energy counter which counts up and down depending on Energy consumed v.s. returned. This value is a ‘lifetime’ counter which is now negative (-1400 kWh). I configured this as ‘Grid consumption’ and added the solar to ‘Solar production’ but don’t know how to configure ‘Return to grid’.
A it is now it only shows the Solar energy flowing to ‘Home’ and not the consumption and delivery to the grid. Any ideas?

how can i get the gauge metter on the energy dashboard ?

Maybe i oversee this topic too simple, but:
why not just enable anyone to add any sensor to the config for monitoring?

E.g. i use several Shelly (Plugs) and other additions which also monitor energy, these also show up as entities.
At least for me, this would be more sinmple to just add from the whole entities list.
Yes, i know this may show more as needed, but it would be more simple at least to me without adding specific config lines…

maybe because the energy integration needs those attributes? How do you think it can calculate daily stuff without last_reset etc.? Developers aren’t stupid, if they filter sensors based on those attributes it’s because it’s a prerequisite for the correct functioning of the integration, not because the list would get too crowded.

Hello,
i just found this tread - i posted my question in another tread regarding energy management.

I have some trouble setting up the new Energy Dashboard.
I can not select the entity.

Here the Configuration:

I tried many approaches from several treads but i cant get it to work.

What did i do wrong?

Thank You!

please show the screenshot of the total_in sensor from dev tools, want to check the attributes from HA’s point of view.

The unit of measurement shouldn’t have a space, and doesn’t need quotes, it should be like this:

unit_of_measurement: kWh

alexdelprete · August 17, 2021, 10:56am

just modify unit of measurement…I don’t see other issues.

Hassio77 · August 17, 2021, 10:56am

can i do this by editing customize.yaml?

sorry - i am not that experienced.

alexdelprete · August 17, 2021, 10:58am

This is your customize.yaml, just modify the unit_of_measurement like I told you, then restart and post the dev tools screenshot again:

i just shared my thoughts with nthis topic as beeing new to energy. So no need of beeing that attackable, please.

I thought that it would do time coun ting itself (e.g. as with power meters from a light sensor). But now i undestand there is more insights i did not think of. Understood better now.

Will try to achieve same with the configs explained above.

I didn’t attack you, I even explicitly put a smile at the end of the post just in case…but I see it didn’t work. Sorry if you interpreted like that, it was just ironic, not aggressive at all.

Just for reference, here’s one of my sensors, that are picked up correctly by the integration:

Hassio77 · August 17, 2021, 11:38am

This solved the problem

No graphic statistic data showing up yet - but a few hours wait should fix that.

Thank You so much!

alexdelprete · August 17, 2021, 1:03pm

Glad it’s working now.

Hassio77 · August 17, 2021, 2:34pm

Will it ,over time, give me monthly statistics ?
Or is it just day by day?

malosaa · August 17, 2021, 4:14pm

Anyone else seen that the calculation of peak and offpeak not correct on energy page?

Well i setup a long time ago with the same device a (utility_device) that calculates the daily usage.
After a day i checked and on the energy dashboard it says i consumed total (4.93kWh) and on my utility_device it’s (4.80kWh) i have a dmsr 5 meter so it goes automatically to peak offpeak and i use the Cumulative device…

When i check the saved (Cumulative device) and do some math the utility_meter shows the correct value…

I have a sensor that mesures the current used at all time, so i want to transform it to kWh, which i have done with a template sensor (see code at the bottom), the template sensor works fine, but it doesn’t turn up as a device in the energy management. Somebody suggested using “last_reset” but that doesn’t seem to be possible with a template sensor? I get a config error if i use “last_reset”. Any tips?

- sensor:

    - name: test_kwh

      unique_id: test_kwh

      unit_of_measurement: "kWh"

      device_class: energy

      state_class: measurement

      state: "{{ states('sensor.test_energy')|float * 0.240 }}"
