Powerplay compensation sensor

[martijnrusschen]

Zonneplan has added Powerplay support for their PV panel customers. See https://www.zonneplan.nl/powerplay/zonnepanelen. I'm seeing the first compensation since today, as you can see in the screenshot below:

I'd love to see if there's a way to add this as a sensor to Home Assistant so i can track the additional income of this feature without having to check their app. Same with the status, it seems they indicate in the app when it was active which I guess could be exposed in their API as well.

TLDR:

• Sensor for Powerplay compensation
• Sensor for PV status (is Powerplay pausing my inverter?)

I've looked into the logs, but couldn't find any field yet that really does what I'm looking to get here. Perhaps I haven't looked closely enough yet, but curious if these asks are reasonable.

Sensor for Powerplay compensation

Can you post your logs?

Sensor for PV status (is Powerplay pausing my inverter?)

Need to check though that there was some state value in de api data. But see that's currently not available as a sensor.

@martijnrusschen can you check your logs for the value powerplay and grid_stabilization_active?

Need to check though that there was some state value in de api data. But see that's currently not available as a sensor.

Could be! I can see different statuses as also shown in the screenshot, the status will say for example "Productie gepauzeerd" when Powerplay is pausing the PV inverter. In normal situations the status reports like you can see in the screenshot.

Powerplay mentions in the log:

I don't see a mention of grid_stabilization_active. I can share the full logs but need to redact some info. what's the best way to share? And since it seems there are multiple types of requests, do you need all of them?

[fsaris]

You can send it to me for example using direct message on the forum https://community.home-assistant.io/u/minifranske/

The log that starts with [custom_components.zonneplan_one.coordinator] Result should give the info. But the other logs could also be helpful

[martijnrusschen]

Done.

[fsaris]

Can you test https://github.com/fsaris/home-assistant-zonneplan-one/tree/2024.4.0b1 to see if this give some more info about the powerplay status.

Couldn't find anything yet related to the compensation values

[martijnrusschen]

Installed the beta version, will monitor the statuses tomorrow to see when and if they change.

👍🏼

I'm curious if the following sensors give some meaningful values:

• Dynamic control enabled
• Expected surplus
• Power limit active
• Current scenario
• Powerplay

[martijnrusschen]

Current status:

• Dynamic control enabled: On
• Expected surplus: 0 kWh
• Power limit active: Off
• Current scenario: Unknown
• Powerplay: Unknown

[martijnrusschen]

Update:

Zonneplan paused the inverter just now. Here are the statuses:

[martijnrusschen]

Power limit active changed to "On" Current scenario changed to "1"

[martijnrusschen]

Current scenario: 1 = Afregelen

[fsaris]

So only power limit active is relevant?

Does Expected surplus or Powerplay change?

[martijnrusschen]

Here's a good overview of the different sensors during a Powerplay moment yesterday:

It looks like the main sensor to track is the power limit active, and the timings perfectly sync with the current scenario sensor. I haven't been able to tell the difference between 0 and unknown in this sensor yet. Perhaps more time will tell.

Update:

This is working great so far. I made a helper sensor to capture a more friendly text of the current powerplay state in my own config:

powerplay_friendly_status:
      friendly_name: "Powerplay Status"
      value_template: >-
        {% if is_state('sensor.zonneplan_one_optimized_omvormer_current_scenario', 'unknown')  %}
          Bescherming aan
        {% elif is_state('sensor.zonneplan_one_optimized_omvormer_current_scenario', '0') %} 
          Afregelen
        {% elif is_state('sensor.zonneplan_one_optimized_omvormer_current_scenario', '1') %} 
          Afregelen
        {% else %}
          {{ states('sensor.zonneplan_one_optimized_omvormer_current_scenario') }}
        {% endif %}

So far, it's only been unknown, 0, or 1. There are scenarios that I haven't encountered yet (disabled because of negative price) and I assume it's just a matter of waiting until those show up.

Sensor improvements can be added in follow ups
