Can I set the state of a sensor from within HA?

Hi all !

I have a stove I am monitoring, and here are the states it reports :

from its remote controller, I can configure the fan modes. But I would rather figure out a way to change its real_power value.

Question: is this feasible ? Or is it a one way communication channel making it impossible to change a sensor state value from within HA ?

An entity has one state value and can have multiple attributes. What is shown in your screenshot are a climate entity’s attributes. A climate entity has several services to control it but none of them are designed to directly change the value of real_power.

Which integration did you use to produce this climate entity for your stove? Sometimes the integration provides additional services.

# Custom component integration in Home Assistant

**Warning: this integration is not tested with multiple devices, there is no guarantee that it will work with your Agua IOT heating device.\
It's also not guaranteed that this custom component will keep on working in future Home Assistant releases due to architectural changes for example.**

This custom component has been tested with Home Assistant 2020.12.1 and one Agua IOT heating device (Eva Calor stove).

## Installation

1. If it does not already exist, create a `custom_components` directory in your Home Assistant config directory
1. Copy the [aguaiot](custom_components/aguaiot) folder and its contents into the `custom_components` directory within your Home Assistant config directory.
1. Restart Home Assistant to load the custom component.
2. Open the Home Assistant web interface and go to `Integrations` and add the `Micronova Agua IOT` integration using the Agua IOT API url and customer code of the brand of your heating device, and the email address and password that you use to login and manage your Agua IOT heating device.

After following the steps above you should now be able to see your heating device as a device in Home Assistant.

this is the one, but I could not find anything about a way to change the attribute of this real_power state

Its a custom integration that provides no additional services beyond the ones available for the climate integration. Therefore, as mentioned, there’s no service call to set the value of real_power.

There is a python_script posted elsewhere in the forum that can be used to change the value of any attribute. However, this change is not communicated to the physical device and is not permanent. If you restart Home Assistant (or the next time the integration refreshes its attributes) the attribute’s value becomes whatever the integration sets it to and not what you had set it to with the python_script.

It sounds a little too hacky to control a device which is “mechanical” per se.
I will avoid breaking things I guess for this time

thanks for your help @123
