Welcome to Catalina Computing, home of Virtual Wiring.
Using our free for non-commercial use software and widely available 3rd party components, you can build all these things, quickly and cost effectively - without programming.
The Virtual Wiring System
The Virtual Wiring System turns *nix computers (Macs, Linux PCs, Raspberry Pi’s, BeagleBone Blacks, etc.) into robust, control systems. The system is operated entirely from the web or a smartphone, and requires no programming. Just define the problem you are trying to solve, pick your *nix host, and assemble your solution using Virtual Wiring and any of 1000s of available devices.
All the physical devices used for building systems are available from 3rd parties (and are often multi-sourced). The Virtual Wiring system runs on PCs, Macs, Raspberry Pi's, BeagleBone Blacks, and almost any other *nix platform. Once your system is up and running, you can control and monitor it from cell phones, tablets, laptops, and desktop computers using almost any web browser.
What We Offer
We've got great online documentation describing how to install the software and build your own systems.

A Smartphone Application for Virtual Wiring
We've built a home automation system controlled by an application on your smartphone. Use Blynk to control anything in a Virtual Wiring system. See our Blynk Home Automation Project.
Check Out Our Home Automation Project
Virtual Wiring automated an entire home! We've just added a link to an article published in Raspberry Pi Geek magazine.
Want to Build an Alarm System?
How about an alarm system that costs less than $100 that can monitor multiple sensors and sends you email and text messages? Or how about one that's dead simple to operate? Read about them in our Low Cost Alarm and INSTEON Alarm projects.
Wireless Bluetooth Sensors
We support a family of Bluetooth sensors for measuring temperature and light - no wires needed!
