@mfalkvidd Very cool. I'm not looking at more than that so the setup I have in mind should work. Thanks for the help! I'll probably bug you guys more in April-May when i get back home.

So I'm trying to figure out your set up. Obviously you have other sensors, but is this your controller? Gateway? What type of network did you use? I'm trying to learn how to use the MySensors Library and your project has me intrigued. I'm wanting to control various slaves that make use of digital potentiometers.

I have a project in mind that I think is similar to yours. Essentially I would have one main unit that issues commands to numerous slaves. Your code is a bit confusing to me. I'm just wanting to make sure I am understanding it correctly. You basically have two pieces to this right? A remote control and then the pumps receiver right? So for all intensive purposes your controller is also your gateway. Are you able to communicate to say 20 other pumps using this same controller?

@mfalkvidd Yes! Perfect place to start. I will look at the controller as a node later. Could the "remote" in the example you just provided still communicate to the 254 total nodes or is it limited? Please tell me it can... My mind will be blown.

@mfalkvidd Ok I'm beginning to understand it. I'm currently in Afghanistan for my job and will be until April. I started researching for this project before I left then stumbled across all this. Sorry for all the question I'm just trying to wrap my head around where this works. So in the example with the "Control Panel." Is the control panel the gateway as well? Also what would the other end look like? How would I send a command to node 42 is what I am asking.

@mfalkvidd The node as a control panel is exactly what I have in mind. Thanks for the direction.

@mfalkvidd Thanks. I looked through and read that page, but couldn't find any code examples on how to assign an id address or any of that. Is there a resource for that?

@hek Also how many devices can you talk to from a single gateway?

@hek Awesome. Thanks man. For now I think I'm just going to use Static IDs. Is there a starter tutorial for creating a small network like what I am talking about? Or even a tutorial just for master to a single slave comms would help me get started.

Awesome! So I'm trying to figure out this architecture. I would have a Arduino Gateway which can have N slaves is that correct? Also the controller thing. I'm just trying to understand. I need a Controller for the gateway correct? Would it be possible to make the Gateway itself the controller with a TFT touchscreen interface? Even better a custom android/IOS/windows UWP app? Is any of this possible?

Thanks in advance
