ok, so if I understand:
- to see outside temperature I need an ESP8266 and a DHT22 temperature sensor
- to see in each room temperature (IN & OUT), humidity and clock, I need an ESP8266, a DHT22 temperature / humidity sensor, a clock for NTP and a 128x64 LCD.
- To view all the rooms simultaneously in a room, I need an ESP8266, a DHT22 temperature / humidity sensor for the REAR CAMERA, and a large LCD so I can see all the monitors at the same time.
Is it right, did I get it right?
Thank you,
