With this small black box, powered on batteries, you can control any infrared device.

A fireplace, a TV, air conditioner, or lights, you can control them all with this device. Also, Christmas decorations, see my dedicated page about this subject.

Learn mode

To learn a new signal, set the device in learning mode by sending this payload to the MQTT topic of the device, for it that zigbee2mqtt/irremote/set

{     
  "learn_ir_code":"ON" 
}

Now a light turned on in front of the device. Now you can hold the original remote in front of the device and press a single button.

The response contains the infrared code to use to resend the signal via this device now.

{
  "battery" : 11,
  "last_seen" : "2024-11-03T09:21:03.343Z",
  "learn_ir_code" : null,
  "learned_ir_code" : "Bb8jphFIAuAXAQF9BuAVA0ABwCPgAwFAE0ABwAdAAUALwANAAUALCcqdvyPBCEgC///gAgcCCEgC",
  "linkquality" : 43,
  "voltage" : 1200
}

Resend signal

To resend the signal, send on the topic MQTT topic zigbee2mqtt/irremote/set this payload to send the same signal as from the original remote.

{
  "ir_code_to_send": "Bb8jphFIAuAXAQF9BuAVA0ABwCPgAwFAE0ABwAdAAUALwANAAUALCcqdvyPBCEgC///gAgcCCEgC"
}

Now the lights also turned on!

Now you can add these commands to your automation.

Home Assistant

Hardware

These hardware devices are examples of what can be used with this automation.

An programmable infrared remote

It can learn signals from the original remote, and via Wifi or Zigbee you can resend the copied signal to simulate the press on the button via an automation.
