    The Global Caché iTach Flex is a compact smart end-point that connects almost any electronic device — entertainment gear, motorized shades, lighting, pool/spa equipment, garage doors — to a wired TCP/IP or WiFi network so it can be controlled and automated from an app.

    Overview

    Slightly larger than a pack of gum, the iTach Flex bridges standalone devices to a network using a 3.5mm Global Port connector paired with Flex Link cables (IR Emitter, IR Blaster, IR Tri-Port, or Serial/RS-232). It includes an integrated web server, onboard flash memory for hosting web pages/files, and built-in IR learning tied to a free cloud-based IR code database — so most common remote-controlled devices can be automated without hunting down codes manually.

    Key Features

    • Connects almost any electrical device to a WiFi or wired Ethernet network instantly
    • Access, monitor, and automate standalone equipment from a smartphone, tablet, or other app
    • Web-based control protocol using HTTP (JSON payload) plus legacy TCP ASCII commands compatible with iTach/GC-100 protocol
    • 4 MB flash memory — store web pages and files accessible via URL for direct device control pages
    • Tiny footprint with a mounting dock for simple, permanent installation
    • Built-in IR learning and access to Global Caché's cloud-based IR code database
    • 4-conductor Global Port for versatility with Flex Link cables (IR Emitter, IR Blaster, IR Tri-Port, Serial)
    • Made in the USA, RoHS compliant
