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 a Temperature Addon:
|
|
- Measures Temperature
|
|
- Generates Values for: Temperature in degrees C and F
|
|
- Required Hardware Module: LM75 or NCT75
|
|
- Required Library: jeremycole/I2C Temperature Sensors derived from the LM75
|
|
|
|
