That entire post has a tone that is offensive. You’re essentially trying to discredit everything that a knowledgeable and credible forum member posted that is actually 100% accurate and true. Your understanding of the contents of this thread is what is wrong and shouldn’t be used to “talk down” to another forum member like he doesn’t know what he’s saying.
“lol” meaning “laugh out loud” meaning “Ha! Lowly peasant! I laugh at your attempt to answer my query! What you say is rubbish!”…yea that’s offensive. One member stating out loud their thoughts about helping someone treating other members like that, no that’s not offensive.
And, that’s not what Curtis is saying. He’s not the end all, be all voice of this forum (sorry Curtis). It’s not a guarantee that you won’t get help here. What he’s saying is, in his opinion, you don’t deserve help from him so he won’t give it. And, in my opinion, he has every right to say that and frankly, is hitting the bullseye. Why would anybody want to spend their time writing a response to anybody when they get essentially talked down to and mocked for a helpful, thoughtful, and accurate response?
I’m beginning to sense the underlying issue here but out of respect, I won’t go there.
As for your original question, since Angus’ scenario is SOOO far fetched for you, here’s another.
As Phil said, the sole intent of the IOT is not for CNCs but essentially a smart switch.
Let’s say I have a home theater room. I can use an IOT relay to power 2 different light settings. One set of lights would be on the Normally “On” outlet. These are the normal lights in the room before playing a movie. I can tie the relay trigger to a DC output of my receiver/preamplifier/whatever so when I turn on the system, it then switches to a different dimmer set of lights that are on during the movie itself. Once I’m done and turn off the system, the normal lights come back on.
That’s why you’d use Normally On and Normally Off outlets.
