Disable a node from another node

General

Hi everyone,
Is it possible to temporarily disable a node from another node?
Thank you!

Can you explain why you want to do that?

Because I read the status of a device and based on the status I modify a home assistant switch. if the state is different from the switch, the switch changes.
However, I also set a flow that when the home assistant switch changes state, an API call starts. these two things overlap in some cases and an API call is made for nothing.

OK I can't envisage that because I don't use Home Assistant so don't know what a HA switch is.

I don't know a way to disable a node without a deploy but there are various ways to block the messages emitted by a node - with a contrib gate node such as node-red-contrib-queue-gate, node-red-contrib-simple-gate, node-red-contrib-semaphore, or even with a switch node and global or flow context variable.

as @jbudd suggests, a simple gate should stop the message flow to a particular node.

A thousand thanks @jbudd e @smanjunath211 !
Simple-gate was what I needed!

That refers to nodes in Kubernetes clusters. We are talking about nodes in a node red flow here. Not the same thing at all.
