List charge slots

The List charge slots action fetches the charge slots from the plan that Ohme generated for your charger. Charge slots are only returned while a charge is in progress.

This action returns its result in a response variable, which you can use in later steps of the same automation or script.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To list charge slots from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create automation > Create new automation.
3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
4. In the Then do section, select Add action.
5. From the search box, search for and select Ohme: List charge slots.
6. Select the Ohme account to use.
7. In the Response variable field, enter a name to store the result, for example charge_slots.
8. Select Save.

This action does not support targets. Instead, you select the account through the Ohme account field.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as ohme.list_charge_slots. Store the result in a response variable so you can use it in later steps:

action: ohme.list_charge_slots
data:
  config_entry: 1b4a46c6cba0677bbfb5a8c53e8618b0
response_variable: charge_slots

This fetches the current charge slots for the account.

Response data

The response contains a slots list. Each charge slot includes the following fields:

• start: The start date and time of the slot.
• end: The end date and time of the slot.
• power: The average power during the slot, in watts.
• energy: The energy delivered during the slot, in watt-hours.

A shortened example of the response looks like this:

slots:
  - start: "2024-11-10T00:00:00"
    end: "2024-11-10T01:00:00"
    power: 7000
    energy: 7000
  - start: "2024-11-10T02:00:00"
    end: "2024-11-10T03:00:00"
    power: 7000
    energy: 7000

Automation: log tonight’s charge slots when the car plugs in

Charge slots are only returned if a charge is in progress. This automation fires the moment the car is plugged in, fetches the planned charge slots, and sends them as a notification. With this automation you can confirm the charger has scheduled charging in the cheapest and lowest-carbon window without opening the app.
