Help in transmitting between arduino


#1

s there a way to transmit between the various arduino connected to the cayenne dashboard ?! for newbies I mean.
I’ll explain the problem. I have a photovoltaic system and I would like to light a resistance only when the difference between production and consumption exceeds a certain threshold. but unfortunately I divided the two arduino who manage the whole thing.

you can use trigger for this. on one arduino calculate the difference between production and consumption and send it to cayenne. then set a trigger to this value and turn ON a button which in turn turns ON the light.


#3

the problem and that are two different Arduino to carry out the task of production and consumption … I’m looking for help


#4

why are you using two arduino for this? can you provide more details.
