Hello Guys,
I am in the process of adding some monitoring for some sensors within my smart home, I have created the following flow which is working well and triggers various things within Home Assistant. The issue I have is I have 30 or so more sensors to set this up for.
My question is, is there a way I can essentially template the flow, defining a string of text which will dynamically update all the nodes within my flow so I can easily copy and paste and reuse it without the task of manually going into each node and changing the text and entities IDs
Something like
Binary\_sensor.sensorname\_offline\_event
Binary\_sensor.sensorname\_offline\_event\_notification\_automation
"Sensor sensorname has gone offline"
etc
thanks in advance

Have a look at subflows, these are basically templates of groups of node with "environment variables" that can be used to parameterise them.
