The P1 splitter has 1 P1 signal input, and 3 P1 signal outputs, it is used for when you want to attach multiple P1 devices on one smart meter.
The P1 data is connected via the included P1 cable to the smart meter. Blinks white when receiving data.
The P1 data out ports that connects to P1 peripherals such as the HomeWizard P1 meter. Blinks white when data is requested by the peripheral device.
green blinking: waiting for P1 signal
green: working correctly
red: May not supply enough power for connected devices to function
off: no power
If the PWR light is off or red, the splitter may require additional power, the best way to do this is by connecting a HomeWizard P1 meter (P1 out) with a USB power supply on the bottom of the p1 meter. The P1 meter will then supply power to the other P1 out ports. If you do not have a P1 meter, you can use the dedicated usb port on the splitter itself for power, this is not recommended when a HomeWizard P1 meter is connected.
