Hello,

I am trying to control the simple-gate-node using change nodes.  
I'm new to Node-Red and really dont know what to do.  
Can someone explain to me how this works?

Kind regards,  
Max

You need to set the the msg.topic to 'control', give me a minute and I'll let you have an example flow.

Almost everything you need to know about using the node is shown in the examples provided when you install it. From the Import item in the "hamburger" menu, select Examples and import the `gate-demo` flow.

 ![control simple gate](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/1/317a0bf8e764f9312870670399efdfdd73113e21.jpeg)

That flow and the one posted by @Paul-Reed should help solve your problem.
