I am going to give you way more context that you probably need to help me because I feel like executing things the way I immagine is kind of dumb for Node-RED and more suitable to a programming language like C.
In my house I have a room where the lights are under a 4 contact step by step relay so that I have 4 "states", all off, all on, half on and other half on.
I have a Sonoff Mini wired so that it simulates a button press. This way I can control it from Home Assistant. The problem is the sonoff has no idea in what states the lights are and neither does HA.
What I wanna achieve is:
- Know which state the lights are in
- Knowing which state the lights are in, asking for a specific state and having Node Red press the button the correct number of times to reach the desired state
My thinking is (right now I am not concerned on how to interface with HA):
I press a button, said button triggers a counter, based on that counter I know what states the lights are in.
Now that I know what state the lights are in, if I have the lights in all off and want half on, node red needs to press the button until the counter is 2.
Problem is I am already stuck, I have a counter, and I know how to reset said counter (node-red-contrib-counter), I want the counter to reset (return to 0) when the button is pressed and when the counter reaches it's limit. (I am trying to use node-red-contrib-bool-gate, but I also tried node-red-contrib-boolean-logic and still didn't manage to use either of them)
While I would like someone to explain how to use the and gate because at this point I spent more time than what I will admit on it, I think this approach is stupid, I feel like I am not taking advantage of node red, since I am passing around messages it probably makes more sense to have all of this informations in a message and not in a counter from where I will need to interpreter, but I have no idea where to start. So, if someone can point me to the right direction it would be very apreciated.
I am including my flow, it basically only has a not working counter on it
