Wiring

ESP               MLX90614
GPIO (4)   <-->   SDA
GPIO (5)   <-->   SCL

Power
3.3V/5V    <-->   VIN
GND        <-->   GND

Note

If you have change the I2C settings in the hardware setup you need to connect to those instead of GPIO 4 and 5.

Setup

Task settings

• Device: Name of plugin

• Name: Name of the task (example name Temp)

• Enable: Should the task be enabled or not

Sensor

• Option: You can either use the IR object temperature or the Ambient temperature. The difference between them is that the IR object is the measured temperature of a remote object and the ambient temperature is the temperature of the sensor itself.

Data acquisition

• Send to controller 1..3: Check which controller (if any) you want to publish to. All or no controller can be used.

• Interval: How often should the task publish its value (5..15 seconds is normal).

Indicators (recommended settings)

Indicator	Value Name	Interval	Decimals	Extra information
IR object temperature	Celsius	10	1	A maximum of 2 digits is outputted by the plugin
Ambient temperature	Celsius	10	1

Rules examples
