ade7953 sensor platform allows you to use ADE7953 single phase energy metering ICs
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).
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.

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.
