+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).
