Hestia controls your Shelly smart-home devices (Gen2 and later) directly on your local network, over HTTP, through their built-in API. No cloud, no account, no telemetry: nothing leaves your network, by default.

Features:

Device dashboard: plugs, multi-outlet strips and smoke detectors, with state, consumption and switch. One tap opens a quick sheet, the full detail is one tap further.
"On for X" timer executed by the device itself, fully autonomously (the phone can be turned off).
Planning (recurring or one-time), with an optional power-threshold cutoff, for example at the end of a charge.
Presence simulation: a script generated by the app runs on the device and switches on/off within a time window, with a random margin.
Smoke detectors: state, battery, alarm mute, and the option to automatically cut a plug off during an alarm.
Configurable physical button and LED on plugs.
Firmware update from the app: check, install, restart the device.
Backup and restore of your configuration in JSON format.

Options, all off by default and explained in Settings:

Instant notifications via ntfy, sent by the devices themselves.
Shelly Cloud: remote fallback for state and on/off, using your account key.
Automatic firmware check, for devices that have Shelly Cloud enabled.

Privacy:

Communicates only with the addresses you enter yourself.
No network discovery, no tracking.
The three options above are the only ones that send data outside your local network, and only if you turn them on.
On Android 17 and later, the local network access permission is requested on first contact, preceded by a clear explanation.

Language: the app is available in French and English, and follows the system language (English by default, French if the device is set to French).
