In Home Assistant 2023.7 a feature was added to allow services to provide a response.
This release brings in a change to Home Assistant, which we consider to be one of the biggest game changers of the past years: Services can now respond with data! 🤯
It is such a fundamental change, which will allow for many new use cases and opens the gates for endless possibilities.
In this release the functionality has only been enabled for a couple of services, but I’m having trouble picturing what we can use this for now and in the future.
What are some use cases you can think of on how to use this new feature?
Users don’t create their own services, services are how you initiate actions with integrated devices and entities.
You’d still need to create automations based on the first method you described, and it’s already extremely simple using an entity group.
