Raspberry Pi Forums

Hello,

I'm looking for a little bit of advice, networking isn't my strong point but here's a basic idea of what I'm trying to achieve.

Assume the following is a floor plan:

I want to have a 'Controller Pi' and then the other nodes will only be accessible via the scope of commands executed by the Controller Pi.

So, effectively the Nodes will only be accessible to the Controller Pi and I would connect the Controller Pi allowing me to then be able to execute commands on the other Nodes.
Node 1 blinks an LED.

Ideally this would also be wireless, but only via a local network not necessarily internet connected (if possible).

Thanks for any advice!

There are SO many different ways of implementing what you ask.
- I can see it made with just a few shell scripts using ssh to remotely execute the commands on the nodes.
- Or you can use MQTT with node-red and control everything from a web-browser.
- Or use Python,,, or C++ or... or..

So what do you know ?
