# HomeWizard P1 Meter

*HomeWizard / HWE-P1*

> The HomeWizard P1 Meter reads electricity import and export and gas from the P1 port of a smart meter over Wi-Fi. Smart meters older than SMR version 5.0 need a USB-C power supply for it. It suits Home Assistant users through an integration (local Wi-Fi control).
