Hi everyone!
I wanna know how can Arduino be used for monitoring and control in smart home systems. And which type of Aurdino shall be used?
the question is way too generic.
what kind of monitoring and control?
what kind of smart home system?
ā write a requirement specification if you want a precise answer
I am using them to replace my existing smart home, which is all hardwired. It has about 128 relays and a bunch of sensors. I am using the Nano with MPC2515 CAN modules for the network. They are inexpensive and very expandable. I have built several custom I/O boards and a 'mother board' for the system. So far all is working fine. All the Mains interface is in approved steel enclosures and have pass inspection years ago. My system is NOT on the internet. If later I want that I only have to build a gateway as the communication etc will already installed and tested. I built it one section at a time.
do you wish to simply add remote internet control to the existing system?
if so does the existing system have central controller?
if so replace with a WiFi enabled device such as the ESP32
if you are replacing the existing nano/canbus system with WiFi control consider the Espressif ESP modules which range from the simple ESP-01S which can have a few sensors and control a couple of relays up to the ESP32 with onboard WiFi, Bluetooth Classic and BLE and multiple IO facilities
