Energy Dashboard

[a-waider]

Hi there,

nice work with this integration :)

Is it possible to use this integration to provide data to the energy dashboard?

[AlgorithmicEntropy]

Yes this is possible, but you need to add some custom sensors to convert the power values to energy. This is possible using this template sensor Energy Template I added my sensors from the configuration.yaml below:

sensor:
  - platform: integration
    source: sensor.energymanager_power_consumed_from_grid
    name: energy_from_grid
    unit_prefix: k
    round: 2

  - platform: integration
    source: sensor.energymanager_power_export_to_grid
    name: energy_to_grid
    unit_prefix: k
    round: 2

  - platform: integration
    source: sensor.energymanager_power_consumed
    name: energy_consumed
    unit_prefix: k
    round: 2

  - platform: integration
    source: sensor.energymanager_pv_power
    name: energy_produced_pv
    unit_prefix: k
    round: 2

After adding these it can take some time for them to show up in the energy config (i think it needs to collect some values before they show up)

Thanks! I added it just now and will test it tomorrow.

So I added the sensors for the myreserve battery with the following coniguration.yaml:

sensor:
  - platform: integration
    source: sensor.energymanager_power_consumed_from_grid
    name: energy_from_grid
    unit_prefix: k
    round: 2
  - platform: integration
    source: sensor.energymanager_power_export_to_grid
    name: energy_to_grid
    unit_prefix: k
    round: 2
  - platform: integration
    source: sensor.energymanager_power_consumed
    name: energy_consumed
    unit_prefix: k
    round: 2
  - platform: integration
    source: sensor.energymanager_pv_power
    name: energy_produced_pv
    unit_prefix: k
    round: 2
  - platform: integration
    source: sensor.energymanager_myreserve_power_in_from_producers
    name: energy_battery_from_producers
    unit_prefix: k
    round: 2
  - platform: integration
    source: sensor.energymanager_myreserve_power_self_supplied
    name: energy_battery_supply
    unit_prefix: k
    round: 2

But I can only see the following sensors in my energy dashboard:

• energy_battery_supply
• energy_produced_pv
• energy_from_grid
• energy_consumed

I also got following warnings in my homeassistant logs:

2021-09-07 11:09:24 WARNING (Recorder) [homeassistant.components.sensor.recorder] The unit of sensor.energy_to_grid (kWh) does not match the unit of already compiled statistics (None). Generation of long term statistics will be suppressed unless the unit changes back to None

Do you know how to delete the long term statistics of energy_battery_from_producers and energy_to_grid?

I tested it myself and ran into the same issue, found this thread on how to fix it by manually editing the database

[AlgorithmicEntropy]

Btw, I´m currently working on integrating the energy stats, which the energy manager keeps itself. This should fix this problem and also provide better stats instead of the calculated ones through homeassistant

[a-waider]

Okay nice, then I'll wait for your new release

[AlgorithmicEntropy]

Hi is just released version 0.2 which adds the new energy sensors I hope you can successfully integrate them in your setup

[a-waider]

Nice work so far 👍 I've noticed some improvements/some things that are unclear to me:

• What is ment by the sensor energy_buffered and energy_released? Could need some explanaition to these entities.
• From where do the entities profit_kwh_to_grid and cost_kwh_from_grid get the values?
• Which entities can I use to track whats going in and out of my battery (myreserve)?
• Maybe rename energy grid into storage into energy from grid into storage (const.py:204)

[AlgorithmicEntropy]

I have not found any official documentation on the meaning of all values, so i had to guess from their json names and how the values correlate with each other, so the explanations below are my best guess :)

• energy_buffered is the sum from all sources into the myreserve
• energy_released i think is the sum of all energy to the grid
• profit_kwh_to_grid and cost_kwh_from_grid are returned by the energy manager, i think they were set by your installer

I track the myreserve as following in the energy dashboard: -> sensor.energy_consumed_storage -> battery out -> sensor.energy_from_pv_into_storage -> battery in

This only tracks pv -> storage -> house, but i dont really care about grid -> storage (sensor.energy_grid_into_storage) or
storage -> grid (sensor.energy_to_grid_from_storage) because these are very small amounts for my setup

Thanks for the hint with the naming, i added a couple missing from to some names to make them more clear in the next release

[a-waider]

Thanks for pointing that out to me. I added the entities like you suggested. I'm closing this now since I believe that this issue has been resolved. Thanks again.
