Mustache Templates in State Changed Node

[sgtpepperaut]

I am using nodered environment variables to reuse flows.
for current state this works great: {{flow.entity}} in the Entity ID field will return the correct Data on Input
Now i would like to use the same flow variable to subscribe to changes to this Entity.

is this possible?

does not work:

At the moment this isn’t possible. The events: state node does not support Mustache templates in the Entity ID field, so {{flow.entity}} won’t work there.

A workable alternative is to use an events: all node and listen for the state_changed event, then use a switch node to compare the event’s entity_id with the one stored in flow context. This lets you effectively “filter” for the entity stored in your variable.
