Getting the room name of the device

There are sensors on doors and windows in every room. Although the names of these are in the form of “door” or “window”, I separate them according to their room names.

I have prepared an automation for all sensors in the system on a single automation as follows. It works smoothly.

But I want to get the name of the room in the warning title or message content and I just couldn’t do it. Can I access this information from device information or what route should I follow.

I would be very glad if you can forward with the sample.

thanks in advance.

Where is the room’s name?

If you are included the room’s name in the entity’s object_id, using a consistent format, then you can extract it. For example, if given this:


We can extract mutfak with this:

{{ trigger.to_state.object_id.split('_')[2] }}

However, in the example you posted, the first binary_sensor has no room name. All the binary sensors would need to follow a consistent naming format.

Instead of adding the room’s name to the entity’s object_id, consider adding it as a custom attribute. Configuration > Customization

It then becomes simple to get the room’s name. Assuming you call the attribute room it’s as easy as this:

Thank you very much for your answer.
Hopefully someday we can easily receive the device room information as you convey below.

good work

Is there an easier and healthier way as below, or will it be added?
In case of a change in room name etc., it seems more healthy to manage from one place.

In order to use this template in an automation’s action

{{ }}

the two binary_sensors in the automation’s trigger

  - platform: state
    entity_id: binary_sensor.kapi
  - platform: state
    entity_id: binary_sensor.hareket_sensoru_mutfak

must have room attributes. You must create the room attribute and assign it a value.

To create the room attribute for each binary_sensor, you can use Configuration > Customization or define it in the customize section of your configuration.yaml file as described here:

And finally the requested feature came with core-2021.9.0…

{{ area_name(trigger.entity_id) }}
