Agent Integration

Designed for scripting and AI agent use with structured, machine-readable output.

# Structured JSON output (auto-enabled when piped)
shelly status -a | jq '.data'

# Consistent envelope: {"ok": true, "data": ...} or {"ok": false, "error": {...}}
shelly -n "nonexistent" status
# {"ok": false, "error": {"code": "DEVICE_NOT_FOUND", "message": "..."}}

# Machine-readable schema
shelly schema

Groups Configuration

Groups are defined in a TOML file:

# ~/.config/shelly-cli/groups.toml (Linux)
# ~/Library/Application Support/shelly-cli/groups.toml (macOS)

[groups]
lights = ["Kitchen Light", "Living Room Light", "Bedroom Light"]
gen1 = { filter = "gen1" }
gen3 = { filter = "gen3" }
all = { filter = "all" }

Or manage via CLI: shelly group add, shelly group remove, shelly group show.
