This is a part of multidisciplinary project "Home automation" this is the hardware side I used an esp32 and micropython.

• Webserver hosted on esp32 (used to configure the hardware).
• Fully costumize you can add as many devices as you want (or as the esp's gpio can handle :p) based on a configuration file.
• Interaction with many devices (MQ2, hcsr04, motion sensor, DHT, Ultrason, Buzzer).
• Sending full report of sensores data to the server using mqtt.
• Receiving commands from the server to interact with devices (RGB light, simple led).
• Alarm on intrusion or fire and sending sms using IFTTT .
