Welcome to the Reactor wiki!

Reactor is a plugin for Vera Home Automation systems that addresses the shortcomings in the built-in logic for triggering scenes and events, adding powerful, user-configurable logic to drive automation.

What Can I Do with Reactor?

If you've ever wanted to do something with Vera/Luup where it's "if this is on and that's off and this sensor is tripped and that device is in this condition", then Reactor is for you. In particular, any time the word "and" appears in the conditions for an automation you are trying to set up, you may need Reactor.

Here are some examples of things you can do with Reactor (many of which would be difficult to do reliably or at all with Vera scenes and device triggers alone):

• Send a notification when the garage door is left open for more than 15 minutes between 10pm and 8am;
• Turn off outdoor lights at 11pm, unless your house is in "Party Mode" (as set by a VirtualSwitch you created);
• Reboot your Vera at 5am every Sunday;
• Temporarily run air conditioning if the humidity in your house exceeds 55%;
• Close the blinds and turn off your pool equipment if the current weather is "lightning";
• Put your Nest thermostat in "Home" mode when your house mode is "Away" but your caretaker uses their lock code to open the front door, and then later return the Nest to "Away" mode.
• Operation
• Reactor is the parent of a set of a ReactorSensors. Each ReactorSensor contains a set of logic conditions that when met, cause the sensor to trip (so, a ReactorSensor implements the SecuritySensor1 semantics). When the conditions are not met, the sensor is untripped. This basic binary output can be used to trigger scenes and other logic, even PLEG.

Reactor itself is a single-instance plugin, meaning all ReactorSensors in the system run from a single copy of the Reactor code, making it light on system resources even for large numbers of sensors and logic conditions.

Donate to the Project

Reactor is free to use, and always will be. Your contributions in support of the project, however, are a big help in both motivation and offsetting some of the expenses related to maintaining this and my other projects (AWS, Github, various developer tools, the Veras I use for testing, etc.). A one-time donation of any amount is appreciated, just jump over to my web site.
