    Example session with this skill installed

    How much do my Shelly devices use, and what is it costing me? My tariff is 6.5 Kč per kWh.

    • Read your context and instructions
    • Compiled the shelly home automation

    scripts/energy_report.py --config ~/.config/shelly-mcp/config.yaml --tariff 6.5 --currency Kč

    Real run on five devices — Gen2 plugs and an RGBW strip, plus two Gen1 relays — read straight from the LAN:

    televize         switch:0  on    105.5 W     35.15 kWh  30d≈494 Kč  lifetime 228 Kč
svetla-kuchyn    switch:0  off     0.0 W     18.05 kWh  30d≈0 Kč  lifetime 117 Kč
mycka            meter:0   off     0.0 W     27.33 kWh  30d≈0 Kč  lifetime 178 Kč
led              rgbw:0    on      5.3 W      3.00 kWh  30d≈25 Kč  lifetime 19 Kč
duo              meter:0   off     0.0 W      0.00 kWh  30d≈0 Kč  lifetime 0 Kč

Total live draw: 110.8 W ≈ 519 Kč per 30 days at this rate

    Values match the MCP server's own shelly_energy_live (TV 35.147 kWh, dishwasher 27.331 kWh).

    About this skill

    Managing a smart home via CLI or chat often feels like guesswork, leading to broken routines or devices switching off at the wrong time. This skill provides a safe, local-first interface for Shelly Gen1 through Gen4 devices by driving the shelly-mcp server with professional-grade caution.

    What it does

    • Device Control manages switches, dimmers, RGBW lighting, and motorized covers using absolute states for reliability.
    • Scene Management bundles multiple device actions into named, deterministic routines like "Movie Night" that execute identically every time.
    • On-Device Scheduling configures sunset, sunrise, and cron-based timers that run locally on the hardware without requiring a persistent server connection.
    • Energy Analytics generates reports on live wattage, lifetime consumption, and cost projections using the bundled energy_report.py script.
    • Safe Execution enforces manual confirmation for multi-room actions and prevents accidental power cycles on critical appliances like routers or freezers.

    How it works

    1. Discovery runs shelly_discover to map the local network and shelly_list_devices to pull friendly names from the configuration.
    2. State Monitoring checks device status, firmware versions, and power draw before attempting any write operations.
    3. Command Execution uses the appropriate tool for the task, such as shelly_switch_set for toggles or shelly_schedule_create for automations.
    4. Validation reports per-device success or failure, diagnosing unreachable units or authentication errors immediately.

    Frameworks & tools

    This skill requires the shelly-mcp server installed via uvx. It interacts with Shelly Gen1, Gen2, Gen3, and Gen4 hardware over a local area network.

    Why this beats prompting it yourself

    Standard prompts often fail to distinguish between device generations or accidentally trigger unsafe "toggle" loops. This skill implements a strict safety playbook, uses hardware-native scheduling instead of fragile software timers, and handles local mDNS discovery that generic models cannot access.

    Use cases

    • Create a "Leaving Home" scene that shuts down all non-essential lighting and appliances.
    • Schedule porch lights to follow seasonal sunset and sunrise times automatically.
    • Audit household energy leaks by identifying devices with high standby power draw.
    • Switch a device on for a fixed time — "TV for 10 minutes" — and let the device switch itself back off.

    Known limitations

    Schedules, scripts and webhooks need a local (LAN) connection; devices reachable only through Shelly Cloud get basic control and status. Gen1 devices cannot be scheduled through shelly-mcp. Sunset and sunrise schedules need shelly-mcp 0.1.3+ and the device location set.
