+  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:
+   --------------------
