While not a homeassistant driver/app, it works with Matter.

For those of you still running Litetouch 2000 lighting systems (there are dozens of us!), I’ve created a Matterbridge plugin that exposes your Litetouch loads as Matter devices. This means you can control your Litetouch dimmers and switches from Hubitat, Home Assistant, Apple Home, Google Home, Alexa, or any other Matter-compatible platform.

Background

Litetouch 2000 was a great whole-home lighting system from the late 90s/early 2000s, but integration options have always been limited. I previously maintained a Vera plugin for it, but with Vera’s decline and the rise of Matter as a universal standard, I decided to build something more future-proof.

What It Does

  • Connects to your Litetouch CCU via RS-232 serial (need special homemade cable, instructions in the github project)
  • Exposes configured dimmer and relay loads as Matter devices
  • Full dimming support (0-100%)
  • Real-time status polling so changes from keypads are reflected in your smart home apps
  • Works with any Matter controller (Hubitat, Apple Home, Google Home, etc.)
  • Workaround for an Apple Home bug that caused lights to go to 100%, and then back down to the requested set level
  • No official support for shades/blinds. Maybe they work? All of my shade motors are dead so I couldn’t test.

Requirements

Installation

npm install -g matterbridge-litetouch

Then configure your serial port and load addresses by editing the config file at ~/.matterbridge/matterbridge-litetouch.config.json.

If anyone else is running Litetouch 2000, I’d love to hear how it works for you. Happy to answer questions or take feature requests.

Does this work with the Standard CCU? I have an 5000LC and a Standard CCU. and would like to use the Standard one for a second project.

Yes. I misspoke, I have a Standard CCU. But it works with both the standard and compact.

I have a 5000LC also that I bought as a spare. I need to program it though so it’s ready to swap right in. I’ve had a lot of relays die on me, and a couple of dimmer modules. Maybe this stuff doesn’t like LED lights so much, but there’s no way I’m going back to incandescent. I have 135 lights and my electric bill was over $700/mo. Knocked down to $135/mo after switching to LED.

All of my switch plates and buttons are almond colored and I hate it. One of these days I’m going to model up the switches and 3d print new ones, engrave them on the CNC for embedded paint, and then paint my switch plates a color that doesn’t scream 1992.

If I get around to programming the 5000LC, I’ll make the plugin support that also. The 5000LC does unsolicited updates over serial, so no need for my polling loop on that platform.

If you NEED 5000LC support right away, I’d be willing to do it on a paid hourly/project basis. Otherwise it’s not a priority right now.
