ADE7953 Power Sensor

Note

This page is incomplete and could use some work. If you want to contribute, please read the contributing guide. This page is missing:

  • A complete configuration example for the Shelly 2.5

  • An image for the front page

The ade7953 sensor platform allows you to use ADE7953 single phase energy metering ICs (datasheet) with ESPHome. These are commonly found in Shelly 2.5 devices.

This sensor can measure voltage and has two channels for reading current and active power (A & B).

Note

SAFETY HAZARD: Some devices such as Sonoff POWs/Shelly/etc, have the digital GND connected directly to mains voltage so the GPIOs become LIVE during normal operation. Our advice is to mark these boards to prevent any use of the dangerous digital pins.

The I²C Bus is required to be set up in your configuration for this sensor to work.

# Example configuration entry
sensor:
  - platform: ade7953
    irq_pin: GPIO16
    voltage:
      name: ADE7953 Voltage
    current_a:
      name: ADE7953 Current A
    current_b:
      name: ADE7953 Current B
    active_power_a:
      name: ADE7953 Active Power A
    active_power_b:
      name: ADE7953 Active Power B
    update_interval: 60s

Configuration variables:

  • address (Optional, int): Manually specify the I²C address of the sensor. Defaults to 0x38.

  • irq_pin (Optional, Pin): The pin connected to the ADE7935 IRQ line (if connected)

  • voltage (Optional): Use the voltage value of the sensor in volt. All options from Sensor.

  • current_a (Optional): Use the current value of the A channel in amperes. All options from Sensor.

  • current_b (Optional): Use the current value of the B channel in amperes. All options from Sensor.

  • active_power_a (Optional): Use the power value of the A channel in watts. All options from Sensor.

  • active_power_b (Optional): Use the power value of the A channel in watts. All options from Sensor.

  • update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.

Use with Shelly 2.5

The Shelly 2.5 device contains this sensor for power monitoring. An example config for the Shelly 2.5 is given below.

There are three oddities with the Shelly 2.5:

  • First, the A and B channels are mixed up - the chip’s A channel is label B on the outside and vice versa. Probably to make the PCB easier to manufacture.

  • Secondly, due to the first point the active_power values are inverted. This is fixed by using a multiply filter as seen in the config below.

  • Lastly, the ADE7953 IRQ line is connected to the GPIO16. The irq_pin MUST be set to GPIO16 to prevent device overheat (>70ºC idling).

Additionally, the device has an :NTC temperature sensor.
