Introduction
Extend the P1 connection of a smart meter wirelessly with the Virtual P1 Master and Virtual P1 dongles.
The Virtual P1 set transfers the P1 telegram from your smart meter to another location over a direct wireless connection. It does not require your home Wi-Fi network or an internet connection.
The set consists of two dongles:
White: Master — connects to the smart meter and transmits the P1 data.
Black: Virtual P1 — receives the data and makes it available on its P1 Out port.
The dongles are paired before delivery and are ready to use. The white Master is normally powered by the smart meter. The black Virtual P1 dongle is powered through USB-C or through a connected P1 device that supplies power.
White Master
Black Virtual P1
The Virtual P1 set only supports V4 and V5 smart meters.
Both dongles have two P1 connections:
P1 Input — located next to the USB-C connector.
P1 Output — located next to the green connector.
Connect the smart meter to the P1 Input of the white Master. Connect the receiving P1 device to the P1 Output of the black Virtual P1 dongle.
The current firmware also forwards the incoming telegram to the local P1 output on the Master. This lets you keep using P1 data next to the smart meter while the same data is sent to the black Virtual P1 dongle.
