Multiple sites/locations


What is the preferred way of using Home Assisant with multiple locations, for example the home in the city and the summer house. I would like to monitor/control things in both locations, and at least be able to monitor/control the summer house from home.

Is there any mechanism in place for this?

Currently I am running one Home Assistant instance at each location.
The sensors/controls that rely on external online service, I can add to both instances.
Is there any way of getting the instances to communicate with each other?
Can events/commands be published using MQTT somehow?

Any thoughts on this?

sorry, I just discovered … -instances

Also in the next version is this:

perfect, mqtt-eventstream is exactly what I need!
