OpenMQTTGateway Addon - ESP8266 or Arduino program for home automation
Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal and a MQTT broker
Send and receiving command by MQTT
This is the Light Meter Addon based on modules with a TEMT6000:
- Measures ambient Light Intensity in Lux (lx), Foot Candela (ftcd) and Watt/m^2 (wattsm2)
- Required Hardware Module: TEMT6000
- Dependencies: none
Connection Scheme:
--------------------
TEMT6000------> ESP8266
==============================================
Vcc ---------> 3.3V
GND ---------> GND
SIG ---------> A0
