Description

Monitor real-time power consumption from Shelly Pro 3EM and control local appliances/automation based on solar yield or grid usage.

README (SKILL.md)

Shelly Sync Skill

Interface between Shelly Pro 3EM energy monitoring and home automation.

Usage Guidelines

Power output in Watts (W) or Kilowatts (kW)
Negative = grid injection (surplus). Positive = grid consumption
If data fetch fails → report connection error immediately, don't hallucinate

Commands

get_status

Returns current power consumption across all 3 phases.

/shelly get_status

optimize_load

Analyzes surplus and triggers load optimization if excess energy available.

/shelly optimize_load
/shelly optimize_load target_load:heatpump

Implementation

Script: shelly_client.py
Calls Shelly Pro 3EM RPC API (EMData.GetStatus)
Returns clean JSON with total power and phase breakdown

Usage Guidance

Review before installing. Only use this if you intend to let the skill control the specific Home Assistant entities involved, and configure the token with the narrowest possible permissions. Treat optimize_load as capable of switching appliances on immediately, especially high-load devices such as chargers, pumps, or washers.

Capability Assessment

⚠ Purpose & Capability

Shelly power monitoring and load optimization are coherent with the stated purpose, but the artifacts show high-impact physical device control when optimize_load is used.

⚠ Instruction Scope

The skill describes threshold-based appliance triggering, and the code can turn devices on when surplus power is detected without a separate confirmation, dry-run, time window, cooldown, or visible allowlist policy.

ℹ Install Mechanism

The artifact appears to be a markdown skill plus an executable Python client; no package installer, startup hook, persistence mechanism, or privilege escalation path is evident.

⚠ Credentials

SKILL.md declares SHELLY_EM_IP, while the implementation also uses Home Assistant URL and bearer-token style credentials, which is materially broader than the declared environment surface.

ℹ Persistence & Privilege

No background persistence or broad local filesystem access is shown; the main privilege concern is credential-backed Home Assistant actuation of local devices.

How to Use

Make sure OpenClaw is installed (local or Docker)
Run the install command in chat: /install shelly-sync
After installation, invoke the skill by name or use /shelly-sync
Provide required inputs per the skill's parameter spec and get structured output
