This sensor outputs an analog signal from 0 to 5V. You cannot connect it directly to CC2530 or CC2531 because they measure up to 3.3V. Therefore you should use a resistive voltage divider.

Type – the sensor type
Frequency and Voltage – parameters of power source where the sensor is attached.
Monitor output – If the firmware controls a power line using the selected GPIO output, it can automatically detect when power is off and start a calibration procedure. Also, the firmware reports zero at that moment.

Zigbee2MQTT commands

read – immediately reads the sensor’s value.

Returns: The counter value {“[channel]”: float_value}
write – starts the calibration procedure for the sensor. The power like should be off (current is zero).
