I’m trying to get two HA instances running with one controlling the other. My main HA instance is on a Synology NAS and docker. The other HA instance is running on a Pi that also has a Razberry card for my z-wave devices.
I have been trying to get this working using mqtt_statestream on the Pi. I can see the state changes of my switches on my main HA instance by creating a sensor subscribed to the relevant topic.
What I would like to do, but haven’t been able to yet, is to control the z-wave devices on the Pi from my main HA instance. Is this possible? If so, how?
I’ve looked at this thread Two HA instances - how to communicate between them? as it appears to be asking the same thing but the control of devices (on/off) doesn’t seem to have an answer.
