Watts Live for Home Assistant

Home Assistant
HACS
Python
MIT licensed

A custom Home Assistant integration for the Watts Live energy meter. It listens to the meter over MQTT and exposes power, voltage, current and energy as native Home Assistant sensors — no polling, no cloud service, no scraping a vendor API.

The sensors are grouped under a single device entity, so your meter shows up in Home Assistant the way a first-party integration would, and the energy sensors feed straight into the Energy Dashboard.

It's written in Python, installs through HACS as a custom repository, and is MIT licensed.

Key Features

MQTT-driven sensors that update in real time as the meter publishes.
Three-phase support for current, voltage and power.
Grouped under one device entity rather than scattered across your entity list.
Energy Dashboard compatible, so consumption tracking works out of the box.

Requirements

Home Assistant with the MQTT integration configured and a broker running.
A Watts Live device publishing to watts/<serial_number>/measurement — you can set that up with Watts Live MQTT BLE Config.
Installed via HACS as a custom repository, or by copying it into custom_components.
