Automate per-room heating control in Home Assistant
A homeowner built an add-on and MCP server so Cursor could write and deploy Home Assistant automations for per-room temperature control, iterating through five versions over a weekend. Task: Suggested implementation: Integrate Home Assistant with Zigbee radiator valves and a relay wired in parallel with the existing thermostat as a fallback. After initial manual YAML configuration, build an add-on and MCP server to enable Cursor to edit, deploy, and restart automations directly from the IDE. The homeowner manually wires hardware, builds the tooling, and reviews all Cursor-generated automations before committing changes to Git.; tools: Cursor. Human role: The original post does not say how a person stayed involved.; limitations: Prerequisites include Home Assistant, Zigbee TRVs, and a relay. Building deployment tooling after the first version is critical for fast iteration, while Git commits enable safe rollback. Source reliability is low due to the 404 error; human approval is required for all wiring and automation deployments..

Overview
A homeowner built an add-on and MCP server so Cursor could write and deploy Home Assistant automations for per-room temperature control, iterating through five versions over a weekend.
Workflow
Suggested implementation: Integrate Home Assistant with Zigbee radiator valves and a relay wired in parallel with the existing thermostat as a fallback. After initial manual YAML configuration, build an add-on and MCP server to enable Cursor to edit, deploy, and restart automations directly from the IDE. The homeowner manually wires hardware, builds the tooling, and reviews all Cursor-generated automations before committing changes to Git.
Reported result
Actual outcomes are unknown as the source returned a 404 error. Proposed acceptance check: Verify that five iterations of control logic can be deployed within one weekend, with the final version switching the boiler off slightly early to allow radiators to coast to target temperature, thereby improving comfort and reducing energy consumption.
Human role
The original post does not say how a person stayed involved.
Limitations
Prerequisites include Home Assistant, Zigbee TRVs, and a relay. Building deployment tooling after the first version is critical for fast iteration, while Git commits enable safe rollback. Source reliability is low due to the 404 error; human approval is required for all wiring and automation deployments.
Try it
I want to automate per-room heating control in Home Assistant using Zigbee radiator valves and a relay fallback. First, perform a dry run: install Home Assistant, configure one Zigbee TRV and the relay, and use Cursor with an MCP server to generate a basic YAML automation for one room. I will manually verify the wiring safety and test the heating cycle. If successful, proceed to deploy the automation. Measure success by the time taken to deploy and validate one automation. If inputs are missing, ask for the specific Home Assistant version and Zigbee device model. Do not publish or spend money without my confirmation.
