Local Home Assistant integration for LaMetric devices using the device API
(lametric-py) with Zeroconf / SSDP / DHCP discovery and a manual config flow.
- Home Assistant 2026.7.3 or later
- A LaMetric device on the local network
lametric-py ≥ 1.3.13(installed automatically as a dependency)
For local development with uv sync --dev, use Python 3.14.2 or later.
Install directly from the HACS default store or copy custom_components/lametric_hass_local/ manually
into your HA custom_components/ folder and restart Home Assistant.
Add the integration in Home Assistant and enter the device host plus API key. If discovery already found the device, only the API key is required.
The API key is available in the LaMetric mobile app under Device -> Settings -> Wi-Fi, or in the developer portal at https://developer.lametric.com/user/devices.
