Where to plug in the home splitter interface

The home splitter interface should be plugged into the P1 port of your smart meter, with its output ports connected to your P1 devices, and powered via USB-C if required.

Connecting the Splitter

For a smart meter P1 splitter, the correct setup is as follows:

• Input Port: Connect the splitter's P1 signal input to the P1 port on your smart meter using the included P1 cable. This is the main connection that allows the splitter to receive data from the meter .
• Output Ports: The splitter typically has multiple P1 signal outputs. Connect each output to your P1 devices, such as energy monitoring dongles, HomeWizard, Tibber Pulse, or other smart home devices .
• Power Supply: If the splitter's PWR light is off or red, it may not supply enough power to connected devices. In this case, use the dedicated USB-C port on the splitter to provide additional power .

Active vs Passive Splitters

• Active Splitters: Recommended for multiple devices. They buffer and regenerate the signal, preventing data collisions and ensuring stable readings for all connected devices .
• Passive Splitters (Y-cables): Simply duplicate the line without signal management. Using these can lead to errors or unstable readings if multiple devices try to read simultaneously .

Additional Tips

• Ensure all cables are firmly connected and check the indicator lights on the splitter to confirm proper operation .
• Avoid cascading multiple splitters unless necessary, as this can degrade signal quality .
• For home network or coaxial splitters, the principle is similar: connect the input to the main line and outputs to the devices, ensuring any powered splitters are plugged in . By following these steps, your home splitter interface will correctly distribute the smart meter signal to multiple devices while maintaining reliable data transmission.
