I wonder how much research was done?

what i mean is: i want to have one Master for switching some Slaves on and off the Slaves must have the possibility to switch manuel too with sending its status to the master

[image] Hedalen: i dont know how to fix a serial wired Master/Slave network with arduino mega 2560 and uno, one Master and several Slaves share your current network and your master + slave code. given its a 'home' wired network I am going to assume you are using some thing as RS485 as you p…

yes, i have RS485 and cables already all over in my house, so how to make the hardware, and the software, so that i can communicate between the master and the slaves. at this moment, i dont have any working serial network here

[image] Hedalen: i have RS485 Means what exactly? If you have existing hardware, you need to detail it for us.

SN75176BP for the network, BT139 triac to switch on off 230V from the output ports 2X arduino UNO 4X arduino mega 2560 i thought, these components will be enough for a network, Right? so not ready motherboards yet
