A project author used an IR sensor to switch a mirror light without touching a control—a useful example of the idea, though the report does not provide a reproducible wiring plan or identify the exact parts.
What each part does
- ESP32: the local controller connected to the light hardware and, optionally, a sensor.
- ESPHome: the device software that configures the light and exposes controls. Its light component supports capabilities such as brightness, color, transitions, and effects where the selected hardware supports them. ESPHome light component documentation.
- Node-RED: the automation layer that can coordinate events—for example, using a sensor event to switch the light or linking the light to other smart-home actions.
The project author describes wardrobe and mirror lights and an IR sensor used for touch-free on/off control. The post does not identify the ESP32 board, LED strip, sensor module, power supply, wiring, or a complete Node-RED flow, so treat it as an example rather than a tested build guide. Project report.
Choose the light before the automation
For straightforward white lighting
A simple white wardrobe strip may be all the project needs. Addressable RGB lighting is not a requirement for ordinary on/off or brightness control; choose a light type that fits the intended use and the ESPHome platform configuration.
For individually controlled pixels or effects
ESPHome documents an ESP32 RMT platform for addressable LED strips. Its configuration includes the data pin, LED count, chipset, and channel order, with WS2812 and SK6812 among the supported chipset choices. That makes a WS2812 addressable LED strip a relevant option when per-pixel control or effects are wanted—not an automatic choice for every wardrobe. ESPHome ESP32 RMT LED strip documentation.

Match the strip to the controller variant and installation length, and verify its voltage, current specifications, LED count, and channel order before buying. The project report does not specify a strip or establish a power budget.
Connect ESPHome to Node-RED
| Connection path | When it fits | Important qualification |
|---|---|---|
| ESPHome native API | When using the community node-red-contrib-esphome nodes directly with an ESPHome device. |
The package listing says the device must have the ESPHome API enabled and marks the package alpha. Check its present compatibility and status before relying on it. Node-RED package listing. |
| MQTT | When the home automation design is organized around an MQTT broker. | ESPHome documents MQTT support on ESP32 and the broker configuration. Its documentation also warns about API and reboot-timeout interaction when MQTT is enabled without the API. Review the current configuration guidance before choosing this route. ESPHome MQTT documentation. |
These are alternative integration paths, not two transports the project necessarily needs at once. Choose based on the rest of the system and the integration you intend to maintain.

Consider an IR sensor for touch-free switching
The project author reports using an IR sensor so the mirror light could be switched without touching a control with wet hands. The report does not name the sensor model or establish a verified detection range, so its anecdotal description should not be treated as a component specification. Project report.
If adding a sensor, select a module whose output type and voltage are compatible with the ESP32 input and the ESPHome configuration you plan to use. A manual switch is a simpler alternative; a sensor adds touch-free convenience but also requires extra compatibility checks and automation setup.

Plan power and installation from component ratings
Select the LED strip and regulated DC supply together using the exact strip manufacturer’s voltage and current specifications for the chosen strip and installation length. The project report and ESPHome component documentation do not establish a project-specific supply rating. An LED channel with a diffuser can be considered as an optional finishing part; it is not confirmed as part of the reported build.
Do not infer mains wiring, isolation, fuse selection, wire gauge, or connector ratings from this project example. Keep fixed mains-side work out of an assumed beginner wiring recipe; use qualified help where installation involves fixed mains wiring.
