At a Glance & Executive Verdict
Nickol Knx MCP
Home Automation · Local stdio
Quality: 44/100 (Fair) | Auth: No auth required
Plugwise MCP
Home Automation · Local stdio
Quality: 55/100 (Good) | Auth: other
Verdict Summary: Choose Nickol Knx MCP if you need specialized Home Automation tools running via a local process. Choose Plugwise MCP if your workspace requires Home Automation integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Nickol Knx MCP when:
You need dedicated capabilities in the Home Automation domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Primary tools included: Read-only .knxproj parsing, DPT, naming, and command/status validation, Home Assistant YAML generation.
Design-time KNX/ETS6 assistant: parses .knxproj (read-only, no bus access), validates DPT/naming/command-status pairing, and generates Home Assistant YAML + ETS XML/CSV exports.
TypeScript-based smart home automation server for Plugwise devices with automatic network discovery. Features comprehensive device control for thermostats, switches, smart plugs, energy monitoring, multi-hub management, and real-time climate/power consumption tracking via local network integration.

Plugwise MCP Tools (16)
add_hub
Add a new Plugwise hub by providing its name (used as password). Scans the network to find the hub and stores it in the /hubs folder as a JSON file for future use. The hub name is the unique identifier printed on the back of your Plugwise device.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Nickol Knx MCP is categorized under Home Automation and uses a local stdio subprocess. In contrast, Plugwise MCP belongs to Home Automation using local stdio subprocess. Select Nickol Knx MCP when you need capabilities focused on home automation and Plugwise MCP when you require tools for home automation.
List all registered Plugwise hubs from the /hubs folder and in-memory registry. Returns hub information including name, IP address, model, and firmware version for each discovered hub.
connect
Connect to a Plugwise gateway (Adam, Anna, Smile P1, or Stretch) and retrieve gateway information. If no host is provided, automatically connects to the first discovered hub. Returns detailed gateway information including model, type, version, hostname, and MAC address.
get_devices
Retrieve all Plugwise devices and their current states, sensors, and capabilities. Returns comprehensive information for all connected devices including thermostats, switches, sensors, and other appliances. Includes current readings, capabilities, and operational states.
set_temperature
Set the temperature setpoint on a thermostat or zone. Supports single setpoint for heating/cooling systems, or separate low/high setpoints for heat pump systems. Changes take effect immediately.
set_preset
Set the preset mode on a thermostat or zone (e.g., home, away, sleep, vacation). Presets apply predefined temperature settings and behaviors configured in your Plugwise system.
get_temperature
Get current room temperature and setpoint for a specific thermostat or zone. Returns both the measured temperature and the target setpoint.
get_all_temperatures
Get current temperatures and setpoints for all thermostats and zones in the system. Returns comprehensive temperature data including measured values, setpoints, control states, and climate modes for every temperature-capable device.
get_temperature_offset
Get the temperature offset (calibration) for a thermostat device. The offset is used to calibrate the temperature sensor if it reads incorrectly. Returns the current offset value and its valid range.
set_temperature_offset
Set the temperature offset (calibration) for a thermostat device. This adjusts the measured temperature by a fixed offset.
control_switch
Turn a switch or relay on or off. Works with Plugwise switches, relays, and smart plugs. Use this to control any switchable device in your Plugwise network.
set_gateway_mode
Set the gateway mode (home, away, vacation). This is a system-wide setting that affects all zones and presets. Home mode uses normal schedules, away mode uses reduced temperatures, and vacation mode provides minimal heating/cooling.
