Hearth

Hearth runs on a Raspberry Pi, speaks MQTT to whatever is on the LAN, and renders a calm single-screen view. No account, no telemetry.

BetaSince 2024

The Challenge

Home dashboards assume a cloud account and an internet connection for what is, physically, a screen in a hallway.

Everything stays on the LAN. Hearth talks MQTT to local devices and renders one calm screen — no sign-in, no outbound traffic.
