What the ESPHome MCP Server unlocks
Connect your ESPHome microcontrollers to any AI agent and take full control of your smart home or industrial IoT setup through natural conversation.
What you can do
- Real-time Monitoring — Fetch the current state and values of any sensor, switch, or binary sensor using the
get_entity_statetool. - Lighting Control — Manage lights with precision using
light_action, including brightness and RGB color adjustments. - Appliance Management — Toggle switches, control fans with
fan_action, and adjust covers (blinds/garage doors) withcover_action. - Interactive Components — Press buttons via
button_press, set numeric values withnumber_set, and choose options from dropdowns withselect_option. - Security & Safety — Arm or disarm alarm panels using
alarm_actiondirectly from your chat interface.

Frequently asked questions about the ESPHome MCP Server
Can I control my lights and set specific colors using this server?
Yes! Use the light_action tool. You can specify the entity name, the action (turn_on), and optional parameters like brightness (0-255) and RGB values (r, g, b) to get the perfect ambiance.
How do I check the current temperature or humidity from my sensors?
Simply use the get_entity_state tool. Provide the domain (e.g., 'sensor') and the entity ID. The agent will return the current value and state of that specific hardware component.
Is it possible to trigger a physical button or restart a device?
Yes. If you have a button entity configured in ESPHome (like a restart button), you can use the button_press tool with the entity name to trigger that action remotely.
