I recently build a second Photovoltaik for my house and added this to my existing System. Due to the external integration the value of the entity for the additional energy is shown negative in Home-assistant. My idea is to create a helper entity and just put a “minus” to this and add it to the existing one.
However I did not find any possibility to do this. Any idea how to create this?
thank you very much. It worked and I could create the helper. Hoewever it’s not possible to add this to the Energy section. See screenshot. It simply does not appear here.
Thank you very much - with the new state class in the helper entity I could now find and add it in the energy section. Thank you.
Just for interest: Is it possible to also change the state of an existing entity? I could only find it in the helper entity i created but not in other entities that are already existing
I don’t think you can change state_class for existing entities, unless you defined them in YAML or the UI in the first place. You can change some things:
