I am planning a home automation and need some suggestions.
I planned to separate each room wiring and connect with arduino so that I can control AC/Fan/lights etc and automate it using different sensors. However if I install multiple NodeMCU or Ethernet shield than how can I control it with single app.
Considering number of switches which would be 5 approx in each room x 8 rooms = 40 switches.
Which option would be better? NodeMCU or Ethernet shield.
As wrings are not planned therefore I am at liberty to do anything, cost is also not a problem.
