Creating a virtual sensor that is aggregated from multiple sensors

Configuration
1

Hello, I’d like to have a device or entity that is updated based on the value of multiple motion sensors. I have 5 motion sensors upstairs in various rooms. I’d like to create a sensor called “upstairs” and to be active if any of the 5 motion sensors upstairs are active. What’s the best way to accomplish this?

Create a group containing the five motion sensors. The group’s state will be on when one or more motion sensors is on and off when all motion sensors are off.

Thanks. That’s what I was looking for. I can’t see a UI to edit this? I have to manage it all in yaml?

Correct; there’s no UI for creating/modifying groups.

You must define them in configuration.yaml as shown in the documentation or in groups.yaml but only if your configuration.yaml file contains this:

group: !include groups.yaml
