At the moment what i have setup is a OpenHAB Controller running on a raspberry pi which is also running MQTT Broker (Mosquitto) and then two arduinos, 1 as a Action node to turn on and off lighting and the other arduino as a Sensor node keeping track of the state of a light switch connected to it as a pushbutton. Everything is working perfectly apart from a little 1 second time delay between pressing the lightswitch and the light coming on. Everything is communicating without fail using nRF24L01 modules.
The question i would like some assistance with is, how many of these nodes can i have connected to the controller. I can see from the datasheet and some research work around the internet that these modules are 6 data pipe MultiCeivers. Does this literally mean i can only have 6 nRF24L01’s talking to each other? If so, i would like to go down the route of having repeaters in my network, so my gateway/controller is talking to 4 repeating gateways, which in turn are then listening to another gateway each, then they are connected to the nodes themselves. Is this possible?
My desired mapping would be as follows:
Could you give your opinions of, am i going about this with the correct and an efficient setup?
