Does the HomeWizard P1 Meter work with HomeKit, Alexa, and Google Home?

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).
