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

:doc:`contributing guide </guides/contributing>`. This page is missing:

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 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 :ref:`I²C Bus <i2c>` is
|
|
required to be set up in your configuration for this sensor to work.

Configuration variables:
|
|
------------------------
|
|
|
|
- **address** (*Optional*, int): Manually specify the I²C address of the sensor. Defaults to ``0x38``.
|
|
- **irq_pin** (*Optional*, :ref:`config-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
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **current_a** (*Optional*): Use the current value of the A channel in amperes. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **current_b** (*Optional*): Use the current value of the B channel in amperes. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **active_power_a** (*Optional*): Use the power value of the A channel in watts. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **active_power_b** (*Optional*): Use the power value of the A channel in watts. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **update_interval** (*Optional*, :ref:`config-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 ::doc:`NTC temperature sensor <ntc>`.
