Installation Prerequisites

Multi-System Reactor is Coming!

Multi-System Reactor is coming! MSR is a platform-agnostic Reactor that is planned to support Vera, openLuup, HomeAssistant, and Hubitat in its first release (and Homey soon after). Sign up for my Discord channel for discussion and updates.

All system requirements are subject to change without notice.

Prequisites for Vera Systems

The following Vera systems and firmware are currently supported:

  • Vera Edge, Plus and Secure systems must be running UI7 firmware at least 7.0.29 (1.7.4452/4453/4453). Version 7.31 is recommended (see callout below).

  • Vera Lite and Vera3 systems must be on UI7 7.0.27 (1.7.1040), the final firmware release for these systems. These systems are EOL and will not be supported after Reactor 3.9.

Reactor does not run on Vera UI6, UI5, or earlier firmware.

Upcoming Vera Firmware 7.32

As of this writing, firmware 7.32 has been announced publicly and is in engineering preview and expected to be released in early 2021. Barring any disruptive changes made prior to general release, 7.32 will, as of that time, become the recommended version for use with Reactor.

Users on 7.0.30 and below

Before installing Reactor for the first time, systems running firmware earlier than 7.0.30 should first be checked for adequate available space on the partition on which /etc/cmh-ludl resides. Ideally, you should have not less than 2MB free space prior to installation. You can check the space available there by logging in via SSH and typing: df -kh /etc/cmh-ludl/

Prerequisites for openLuup

The following are required to run Reactor on openLuup:

  • openLuup version 2020.04.14b or higher (current development version recommended);
  • Lua version 5.1;
  • dkjson version 1.2 or higher acceptable; but 2.5 or higher preferred; it is also highly recommended that LPeg be installed;
  • LuaSocket version 2.0.2 or higher (which should include the mime, socket.http, socket.smtp, and ltn12 modules);
  • LuaSec version 0.8 or higher (version 0.6 might be acceptable for reaching some low-encryption endpoints);
  • lfs recommended, but not required;
  • See "ALTUI" below.

All of the above except openLuup should, if possible, be installed using your OS distro's available installation tools (e.g. apt-get, yum, etc.). Direct installation may be necessary, however, if certain modules or their required versions cannot be installed through these tools.

Prerequisites for ALTUI (on Vera or openLuup)

Reactor currently runs on ALTUI versions 2.46.2536 to 2.52.2550. Reactor will not run on earlier or later versions and they are not supported. If you upgrade to a later version of ALTUI than that supported, the Reactor UI may not function and could cause data/configuration loss. You should downgrade your ALTUI to the highest supported version until the newer version is certified for use with Reactor.


ALTUI is not just a very different UI for Luup, but also a significantly different development environment from that provided by Vera UI7. It is similar to, but not entirely compatible with, UI7. As a result of these issues, not every release of ALTUI will be supported.

Specific Browser Requirements for the Reactor UI

Above and beyond the platform's requirements, the Reactor UI for editing conditions and activities is, by its nature, information-dense and very task oriented, with complex interactions. It necessarily "pushes the envelope" and does things not typically seen in the more basic UIs of other plugins. The Reactor UI requires:

  • Current Chrome, Brave, Firefox, or Safari running natively on modern Windows, Mac or Linux (desktop);
  • Display size of 1024x768 minimum, larger than 1280x800 recommended;
  • JavaScript enabled.

I do cursory testing on Edge and Opera, but these are not recommended configurations and I do not go out of my way to fix bugs for them. While you may be able to get something done on a mobile device with a smaller-than-recommended display and device-specific browser, it won't be a fun way to work and isn't a supported configuration (i.e. I won't fix bugs or layout problems unique to those devices).

Got a UI Bug?

If you think you've found a UI bug, please (a) make sure you are on one of the supported configurations enumerated above, and the browser is up-to-date; and (b) retry the operation after starting your browser with all extensions disabled (some browsers offer a "safe mode" option that does exactly this). If the feature works with extensions disabled, you should probably report the issue to the extension developer/maintainer.

Installing Reactor

Backup First!

A full backup of your system, including the ZWave network, is always a good idea before making any important system changes.

From the Vera Plugin Marketplace (Vera)

Reactor can be installed via the "Install Apps" function in the Vera UI. This is the recommended approach for Vera systems. Use the search function there to search for "Reactor" and it should pop right up.

From the AltAppStore (Vera & openLuup)

The AltAppStore (under ALTUI) offers all current releases of Reactor as well as the current stable development branch. To install, find Reactor in the AltAppStore, choose the version you'd like to install, and click the "Alt" button.

Directly from Github (Vera & openLuup)

To download the plugin from Github:

  1. Go to the Reactor Github repository;
  2. Choose the branch for the version of Reactor you want to download:
    • master: the master branch is the most recent released version;
    • hotfix: the master branch plus any important fixes that have come up since the master release — this version is expected to be at least as stable as master, if not more.
    • stable: the latest development release for which basic QA has been completed — may still contain bugs, but they should be trivial;
    • develop: the latest developer code changes checked in, with minimal QA — this version will be the bleeding-edge of functionality, but may also contain bugs (from the most trivial to soul-crushing, crash-inducing horrors);
  3. Click the green "Code" button, and choose "Download ZIP" from the pop-up;
  4. Save the ZIP file somewhere;
  5. Unzip the ZIP file;
  6. Upload the unzipped files to your system.
    • For Vera, the uploader at Apps > Develop apps > Luup files is recommended. Select all of the unzipped files except the ".md" files and drag them as group to the "Upload" button in the Vera UI and drop them there.
    • For openLuup, use whatever tool you wish to move the files into your openLuup directory. Make sure the permissions allow at least read access for the openLuup process. Reactor also requires write access to the directory in which it is installed to upgrade its device information database and create log files.
  7. If and only if this is a first-time installation of Reactor on the system, create the Reactor master device:
    • On Vera, go to Apps > Develop apps > Create Device;
    • On openLuup, use ALTUI's "Create Device" button in the Devices view;
    • When asked, supply the following to your platform's form (other fields may be left blank):
      • Name or Description: Reactor
      • UPnP device filename: D_Reactor.xml
      • UPnP implementation filename: I_Reactor.xml
    • Click the form's submit button once to create the device.
  8. Then reload Luup and hard reload/cache refresh your browser.
