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

      - 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 <https://www.analog.com/media/en/technical-documentation/data-sheets/ADE7953.pdf>`__)
with ESPHome. These are commonly found in **Shelly** 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 :ref:`I²C Bus <i2c>`
or :ref:`SPI Bus <spi>`
is required to be set up in your configuration for this sensor to work.

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 ::doc:`NTC temperature sensor <ntc>`.
