Global Caché
Global Caché builds the control gateways that put infrared, RS-232, and contact-closure equipment on an IP network. Home Assistant drives the IR side through the itach remote platform and the relay and digital-input side through the gc100 integration, both entirely local over TCP port 4998. This is the standard way to bring projectors, AV receivers, older matrix switchers, and dry-contact gear into a Home Assistant install.

IR & Serial Control
10 devicesGC-100-06
The GC-100-06 network adapter combines three IR ports and one RS-232 port in a single Ethernet-connected box. It is the entry point of the GC-100 range that Home Assistant's itach and gc100 integrations are written against, and it is still the unit found in a great many existing AV racks.
GC-100-12
The GC-100-12 network adapter carries six IR ports, two RS-232 ports, and three relays in one Ethernet box. It is the Global Caché unit Home Assistant's gc100 integration is documented against, and the one that covers a whole rack of IR gear plus dry-contact loads from a single IP address.
iTach Flex FLEX-IP
The iTach Flex FLEX-IP is a single wired gateway whose function is set by the cable you plug into it: IR, RS-232, RS-485, or relay and sensor. It speaks the same TCP API as the iTach and GC-100, so with an IR cable fitted Home Assistant drives it through the itach remote platform.
iTach Flex FLEX-WF
The iTach Flex FLEX-WF is the Wi-Fi version of the Flex gateway, a gum-pack-sized endpoint whose role is set by the Flex Link cable fitted to it. With an IR cable it answers Home Assistant's itach remote platform; with the relay and sensor cable it answers the gc100 platforms.
iTach IP2CC
The iTach IP2CC puts three dry-contact relays on a wired network, for the gate operators, fireplaces, screens, and pool equipment that only accept a momentary or maintained contact. Home Assistant drives Global Caché relays through the gc100 integration's switch platform.
iTach IP2IR
The iTach IP2IR is the wired TCP/IP to infrared gateway that Home Assistant's itach remote platform is written against. Three selectable IR output or sensor ports let one palm-sized box drive a projector, an AV receiver, and a cable box over Ethernet, entirely locally on TCP port 4998.
iTach IP2SL
The iTach IP2SL puts a single RS-232 device on a wired network, exposing its serial port as a raw TCP socket on port 4999. Home Assistant has no Global Caché serial integration, so it reaches the port through whichever integration already speaks that device's protocol over a socket.
iTach WF2CC
The iTach WF2CC is the Wi-Fi version of the IP2CC, giving three dry-contact relays a network connection where no cable reaches. It is the practical way to put a detached gate, gas fireplace, or pool controller under Home Assistant through the gc100 integration.
iTach WF2IR
The iTach WF2IR is the Wi-Fi version of the IP2IR infrared gateway. It exposes the same three selectable IR output or sensor ports and the same TCP API on port 4998, so Home Assistant's itach remote platform drives it identically, without a network drop at the equipment.
iTach WF2SL
The iTach WF2SL is the Wi-Fi version of the IP2SL RS-232 gateway, bridging one serial device onto the network without a cable run. It carries the same DB9 port and the same TCP socket on port 4999, and the same Home Assistant caveat: there is no Global Caché serial integration.
