Integrate Cheapest Energy Hours Macro

[greteOne]

Hello everyone,

not an issue but unfortunately the best place for this idea:
is it possible to include the following macro via a helper entity, for example, so that dynamic charging according to the cheapest energy price would be possible? The combination of the add-on with the macro would be a gamechanger in my eyes.

Kind regards

Hi @greteOne,

Thanks for your feature request!

This feature could automatically define start_hr and end_hr in the SBAM configuration. While I’m not familiar with this extension, if someone wants to create a PR to implement it, I’m fine with that.

Possible Implementation

• Introduce a boolean variable, auto_setup_time_range (default: false).
  • If true, start_hr and end_hr will be defined via the output of the macro (via API request ?).
  • If false, they will be defined manually as usual.

I’ve labeled this as a Good First Issue for anyone interested in contributing.

think that the boolean and the start time are sufficient. The easiest way would be to integrate the start time as an entity as a timestamp.
The specification for the end time results from the maximum charging power from the grid to the battery and can be included in the macro.
What is the maximum charging power from the grid?
