Set price cap

The Set price cap action sets the price threshold above which your Ohme charger stops charging. You can switch the price cap on or off with the Price cap switch entity.

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 set the price cap 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: Set price cap.
6. Select the Ohme account and enter the Price cap.
7. 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.set_price_cap. A basic example looks like this:

action: ohme.set_price_cap
data:
  config_entry: 1b4a46c6cba0677bbfb5a8c53e8618b0
  price_cap: 15

This sets the price cap to 0.15 in your local currency.

Automation: set the price cap every morning

This automation sets the price cap to 20 p/kWh (2000 in 1/100ths) every morning so the charger never draws grid electricity above that threshold during the day.

actions:
  - action: ohme.set_price_cap
