Homebridge Global Caché iTach IR

Introduction

This Homebridge plugin supports sending IR commands via Global Caché iTach IR products:

• WF2IR
• IP2IR
• IP2IR-P

Documentation

This plugin is based off of the Homebridge Broadlink RM Pro plugin so start with its documentation.

Important differences:

• No automatic discovery. You must manually provide the hostname or IP address of your iTach device.

• No IR learning.

• No MQTT.

• No ping/arp support.

• Only the following accessory types are supported:

  • switch
  • outlet
  • light

• Instead of a hosts array, add a single host: <hostname or ip address> at the top of the platform config. This is the default host that any accessories that don't have the own host: <hostname or ip address> will use.

• The "data" strings must adhere to the iTach API sendir syntax, less the sendir, prefix. e.g.

  {
      "name": "Accessory Name",
      "type": "switch",
      "data": {
          "on": "1:1,0,38000,1,1,129,65,16,...",
          "off": "1:1,1,38000,1,1,129,65,16,...",
      }
  }

  i.e. <connectoraddress>,<ID>,<frequency>,<repeat>,<offset>,<on1>, <off1>,<on2>,<off2>,....,<onN>,<offN>

  • <connectoraddress>: 1:1, 1:2, or 1:3 to send the command via IR port 1, 2, or 3.
  • <ID>: a value between 0-65535.

  Hint: Sign up for Global Caché's Control Tower and have the codes e-mailed to you. It's a huge database and this is easier than learning all the codes.

This plugin is based off of https://github.com/kiwi-cam/homebridge-broadlink-rm. I removed most of its accessory types and adapted the remaining code to work with the Global Caché iTach protocol.
