Lumiz lampions are decorative, solar- or battery-powered lanterns designed for both indoor and outdoor use. Many Lumiz models come with an infrared (IR) remote control, allowing you to easily adjust brightness, switch the lamps on or off, or timer selection.

The Lumiz remote typically uses a standard IR LED transmitter operating at 38 kHz. Because these IR signals follow a repeatable digital pattern, they can be replicated by an ESP8266 or ESP32 microcontroller equipped with an IR LED. This makes it possible to automate or remotely control Lumiz lampions through Home Assistant with ESPHome — for example, have them turn on automatically at sunset or adjust brightness without ever touching the remote.

By capturing and transmitting these codes (in Pronto format), your microcontroller can behave exactly like the original Lumiz remote — allowing seamless integration of decorative lighting into your home automation system.

Hardware:

  • Lumiz solar lantern
  • Lumiz battery module
  • ESP8266 ESP-01 (1 MB version)
  • IR LED (connected to GPIO2 through a transistor or MOSFET for sufficient current). I use the RobotDyn IR module that contains a transistor and resistors.
  • Resistor for input signal (1 KΩ on base of npn transistor such as 2n2222)
  • Resistor for LED (typically 100–220 Ω for IR LED)
  • (Optional) IR receiver (e.g., TSOP38238) connected to GPIO0 for debugging or learning new IR codes

Once configured, home assistant sees it as a dimmable monochromatic light, allowing you to control brightness and power states seamlessly.
