I'm trying to read the battery level from a Fire controller but even the init code is not working. Is this function not supported for Fire controllers? In the schematic I see that a IP5306 power controller is used in the hardware. So I don't understand why canControl() returns false.

  M5.begin(); 
  M5.Power.begin();
  if (M5.Power.canControl()) {
    Serial.println("Power canControl OK");
  } else {
    Serial.println("Power canControl ERROR");
  }

I'm always getting the ERROR message.

Thanks, Roger
