Home Assistant state update trigger in Node-RED

To trigger a flow in Node-RED based on an event updates in Home Assistant you can use the node ‘events: state’

An example is to send a message (in this case, to the debug node, replace it with your own chat app) when it’s a full moon.

The configuration of the state node:

Server     Home Assistant
Entity     Moon Phase [exact]
If state   [is] [a-z] full_moon
For        [0-9] 0 [minutes]
