Script action and custom timers

[toggledbits]

Reactor build 25067

• Fix a runtime error thrown when creating a Reaction in a Rule Set.
• Fix a race condition causing a runtime error in some browsers when the "Exit" button is hit on a Reaction Editor instance. The error was discovered to be more reliably reproducible when the Reaction being edited had a group (i.e. used an interior/child instance of a Reaction Editor).
• Fix deletion of global expression.

There are workarounds for the first two issues if upgrading is a hassle for you. For the first, create the Reaction under Global Reactions and then move it to the target Rule Set. For the second, you can safely ignore the error as it occurs after all save and cleanup have already taken place.

Reactor build 25082

NOTE: Bare-metal users, please run npm run deps in your Reactor directory after updating, then restart Reactor. Generally, you should always do this after upgrading to a new build, but for this build in particular, it's necessary.

• Status Tab: fix an error that could cause lost notifications on object changes to some widgets.
• Packages: update some packages and force one dependency to eliminate a warning from node about a deprecated subsystem (not every package has caught up yet).
• Reactor UI: improve cleanup and memory utilization of tabs when switching between them.
• Engine: The isRuleSet() and isRuleEnabled() expression functions now trigger re-evaluation of expressions in which they appear when the subject rule changes state.
• HassController: Bless Hass to 2025.3.4

ZWaveJSController build 25082

This build of ZWaveJSController requires Reactor build 25082 or higher.

BREAKING CHANGE: For RGBW/RGBWW devices, the color_temperature capability is no longer used; white channels will now be mapped to the dimming capability. If you have such devices and use color_temperature attributes and actions, you will need to make appropriate adjustments to your Rules and Reactions.

• Add support for start and stop heal actions (in zwave_network capability).
• Improve connection retry decay computation (use slow initial decay with rapid ramp).
• Improve handling of white channels in RGBW/RGBWW devices. Mapping them to color_temperature seems to be incorrect in most cases, so they are now mapped to dimming. If the device has multiple channels, the white or color channels may be pushed to child entities.
• The zwave_device.set_value action now accepts JSON in the value fields for Z-Wave JS values that support it. Some devices are able to report or set multiple values simultaneously by using a dictionary as the value (aka JSON object with key/value pairs). RGBWW devices, for example, may support the currentColor and targetColor property with a value object like { "warmWhite": 0, "coldWhite": 0, "red": 128, "green": 0, "blue": 240 }.

Reactor build 25097

• Expression syntax enhancement: it is now possible to use a variable's value as a key when creating an object on the fly. For example, if the variable cmd contains the word "econo" (presumably derived from configuration or some other dynamic source), it is now possible to create an object { econo: true } by enclosing the key source in square brackets: obj = { [cmd]: true }. For reference, this syntax mimicks JavaScript.
• Fixed a UI crash when bringing up Reactor initially after using the About page bypass.
• OWMWeatherController: implement sys_system.restart, which will cause all locations to be refreshed immediately.
• OWMWeatherController: new config option (boolean) ignore_certs can be set to ignore certificate errors. These seem to pop up occasionally, perhaps because of a misconfiguration in the load balancing at OWM.

Reactor build 25139

BARE-METAL USERS: You must execute the shell command npm run deps in your Reactor install directory after upgrading, to update package dependencies. The UI may not start if you fail to do this. This advisory does not apply to docker containers.

BARE-METAL USERS: nodejs version 18 is End of Life (EOL) as of April 30, 2025, and is no longer supported. For best results and longevity, upgrade to an even-numbered version of nodejs. The current LTS (Long Term Support) version (recommended) is 22 and will go EOL in April 2027.

BREAKING CHANGE FOR DEVELOPERS: If you use Entity.registerAction() and specify a function, the target function now takes the canonical action name as its second argument, and the action parameters will be the third argument (the target entity remains the first argument). That is, the signature of the function has changed from targetFunc( entity, params) to targetFunc( entity, actionName, params).

• Engine: Improve the approach of Rule State conditions to changes in the subject rule's state that don't end up changing the top-level rule state. This should considerably reduce potential throttling that can occur when inter-related/co-dependent rules change.
• Reactor UI: On the Entities list, fixed a minor display error in the display of atttribute values when an attribute other than the entity's primary is selected.
• Reactor UI: Reworked the URL routing so that linking to tabs and objects is possible. For this build, this will be most visible in many (but not all) of the Status tab widgets. More linking will be done in future. There's a lot more to do; please don't bother reporting areas where objects are not linked at this time.
• Reactor UI: The Rule Sets offcanvas navigation now has a search field that allows you to search for a rule by name.
• Upgraded some packages used by Reactor to maintainer's latest versions.
• HassController: Bless Hass to 2025.5.2

ZWaveJSController build 25139

• Minor bug fixes for initialization of devices with scene controller capability.

MQTTController build 25139

NOTE: Uses latest mqtt package, which is version 5.11 as of this writing. You must run npm run deps in the MQTTController install directory to update the package.

• New template support for Shelly Plus 1PM (use include: shellyplus1pm) and Shelly 1 Mini Gen3 (use include: shelly1minig3).
• The query directive in a device configuration now supports payload construction using the same semantics as that for action payload constructions. Principally, this gives you access to expr for query payloads, which facilitates more dynamic construction of payload fields where devices or templates need.
• New inbound topic reactor/:ident/Reaction/:reaction_id/:command; the command may be run, stop, or query to run (enqueue), stop (if running), or query the status of the specified global or Ruleset-based Reaction. You cannot run, stop, or query the state of the SET or RESET Reactions in a Rule. The query command requires Reactor build 25111 or higher for accurate response.

Reactor STABLE Update

The stable branch of Reactor is now updated to build 25139. Please scroll back and see the changes and advisories listed for builds here since the previous stable branch build (which was 24257, 13-Sep-2024), or whatever build you are currently running.

ALL USERS: It's always recommended to back up your Reactor system before upgrading.

IMPORTANT: Bare-metal users (only) need to do the following:

• Update dependent packages by executing npm run deps in the Reactor install directory.
• Reactor no longer supports nodejs versions before 20. If you are running on an earlier version, please upgrade nodejs before upgrading to this build, and make sure your current environment is working. Once you are sure Reactor is happy on the upgraded nodejs, then and only then should you upgrade Reactor to this new stable build. An even-numbered LTS (Long-Term Support) version of nodejs is recommended; the current LTS version is 22.
• If you are running extension controllers like ZWaveJSController or MQTTController in your configuration, you will need to upgrade those to their respective latest versions.

Reactor build 25208

• Status page: fix an issue placing the widget adder tool the first time (i.e. on a new browser or after flushing cache/cookies).
• HTTP Request action now offers storage of the query response in "advanced form." This is a structure (object) that includes the response body as well as the response status, messages, and response headers. The simple form (store body or null) is the default and all existing HTTP Request actions will use the simple form response unless/until modified.
• Telegram notifications now support photo and video messages. To send a photo or video message, select the appropriate Message Format and place the URL or filename in the Message field. Telegram's limits for file type and size must be observed (refer to Telegram's documentation).
• HassController: Configuration for filter_entity now accepts regular expressions to match to entity IDs (i.e. it can now do pattern matching, not just match exact strings). Specify regular expressions in /regexp/flags form (e.g. /^update./i to match IDs that begin with update., case insensitive; flags are optional, and the only flag supported right now is i for case-insensitive matching).
• HassController will requery for service data if the lookup of service data from the startup query does not have the needed info. This can occur when an integration is not fully up and running when HA restarts -- HA will only report on services for fully running integrations at the time. The requery updates the service data for integrations that start later.
• HassController remove old entity mapping configuration that was preventing a mutable attribute (dimming.step) from being changed by the user permanently.
• Expressions: new geodist() extension function to compute Great Circle Distance between two points (presumably on Earth). See docs for details. Example: kilometers = geodist( lat1, lon1, lat2, lon2 )
• HassController: Bless Hass to 2025.7.3

Reactor build 25304

BARE-METAL USERS: It is recommended that you update package dependencies when installing all Reactor updates. After unpacking the Reactor archive, remove any existing package-lock.json file from your Reactor install directory, and then run npm run deps to update package dependencies.

ALL USERS: If you are using extension Controllers (like ZWaveJSController) please update them to the latest versions as well. Please refer to the CHANGELOG files for each for information on specific changes. Also don't forget to update any dependent packages for those extensions — dependent packages are maintained separately from Reactor itself and must be updated individually.

• Rules: POTENTIALLY BREAKING CHANGE the evaluation mechanism for rule-based (local) variables has been changed. Users with rules that rely on specific nuances (or bugs) in the old behavior/mechanism may find their variables and rules do not work as expected. However, most users should find that the new mechanism aligns well with their expectations. See the docs for Variables & Expressions - Overview for a complete description.
• The "Force re-evaluation of expressions and conditions" option available in the Set Variable action of Rule Reactions (SET & RESET) has been removed. When a rule-based variable is used in a trigger, and the variable's value changes, the Rule will now re-evaluate itself automatically. This is part of the above changes.
• Rule Reactions (SET & RESET) now have a "Wait for completion" option. When set, the rule will wait for its Reaction to finish before allowing itself to be re-evaluated. When not set (the default), the Rule will not wait and the Reaction runs asynchronously, and therefore a change to the rule state during the Reaction's execution could cause the Reaction to be pre-empted (stopped before completion).
• Rules: fix handling of some very old rule conditions where the changes operator was stored in an older structure (i.e. handling the legacy structure had a bug).
• A new alarm( interval_seconds ) function has been added; it can be used in global expressions (only) to cause periodic re-evaluation of the expression. This is particularly useful for expressions that don't have dependencies on other variables or entities/objects. A running timer can be cancelled by specifying an interval of zero (0).
• Expressions: fix an error in which the sort() function would sort the array in place rather than returning a new, sorted array (this was in conflict with its specification and intended operation, and apparently existed for a long time).
• UI/Expression Editor: button coordination in expressions editing has been improved, and the highlighting of error messages has been improved.
• HTTP API: A new endpoint /api/v1/variable/:name/update has been added to force re-evaluation of a global variable's expression and, if changed, set its new value. See docs
• HassController HA made a breaking change in 2025.9 (pull 150721) that wasn't declared in their general release notes, affecting the media_player.play_media service. This service also has a new field and selector type, and two fields previously declared have been removed.
• HassController now has ability to filter out entities (i.e. not import entities from HA into Reactor) based on source (integration). see docs
• HassController now supports binding of events directly to Reactions. This is in addition to the existing ability to bind events to entity attributes. Previously, if the user's goal was to run a Reaction in response to an event from HA, the user would need to first bind the event to a new entity and attribute, and then create a Rule triggered by that entity/attribute to launch the Reaction. Now, the Reaction can be launched directly on receipt of the event. See docs.
• DynamicGroupController: A configured group can be disabled by adding enabled: false to its configuration. The boolean value false is the only value that will be honored to disable the group (e.g. null and the number 0, while falsy values, will not be honored).
• Resolve an issue where some Controller subclass' system entities could lose track of their default primary attribute when unserialized (reloaded from storage at startup).
• UI: The rule search tool on the Rule Set left navigation offcanvas also finds Rule IDs that match the entered text (i.e. you can search by name and ID).
• UI: Fix an error that was thrown when using search on the Rule Sets navigation offcanvas list and some existing Reaction had no name.
• UI/Entities: Refresh all displayed entities when a structure event is received from the API (such as when reconnecting after a restart), to ensure the data displayed is the most current.
• UI/Expressions: page will now refresh all expression values when a structure event is received (e.g. after a restart of Reactor), as the Engine start and update of global variables often occurs before clients reconnect to the service, so clients can easily miss the update events from those objects.
• UI/Client API: fix an issue where a group entity could be assigned the wrong entity class.
• UI/Rules: Fix column not wrapping on large value for Rule-based expressions (rule detail card).
• UI/Reaction Editor: the single-action try button (for Entity Actions) now correctly omits optional fields that contain no data, rather than sending blank data and expecting the Controller instance to sort it out.
• UI/Entity Picker: click handler now covers an empty area when no entity has been selected.
• UI/modal dialogs: the ESC key will now dismiss most dialogs; if the dialog is a confirmation, the dismissal is equivalent to hitting "Cancel".
• Pushover Notifier: remove extraneous debug message.
• Developers of Controller subclasses: the Controller method removeControllerGroup() is now deprecated. To replace its functionality, you should now set the class static property createControllerGroup to false. See docs. The old method will continue to be available until October 2026, but will generate a warning to the log, unless the class property is also set, in which case the warning is reduced to informational level (i.e. you can do both for compatibility until next year).
• Tools: added a new trivial backup script.
• Docker images: now built with nodejs LTS (22.20 as of this entry) on Alpine 3.21
• HassController: Bless Hass to 2025.10.4

Reactor build 25308

IMPORTANT: This build addresses two issues in 25304 only. If you are not experiencing these two issues (described below), you do not need to upgrade to this build.

• Expressions: Fix an error thrown when defining a function in a global expression.
• Reactions: fix an issue causing a disabled group to execute anyway.

Additional changes:

• Engine: It is now possible to create constants and functions for use in expressions system-wide that are not defined using global variables. see docs
• UI/Rules: Rule search field on offcanvas now also searches reactions by ID (parity with behavior for rules).
• Rule/Date-Time Condition: work around an anomaly in nodejs v24 (and maybe other versions) that would cause a between condition spanning a DST change to throttle the parent rule.

Reactor build 25310

IMPORTANT: This build was patched and re-released to address a compatibility issue for Home Assistant 2025.11. If you pulled this release before 1pm Eastern Standard Time (18:00 UTC) on Friday Nov 7, please re-pull/re-install this build to get those fixes.

• Expressions: restore ability (lost in 25304) to define a custom function in a global variable/expression and have it be available to other expressions.
• HassController: Bless HA to 2025.11.0

[toggledbits]

Reactor build 25315

NOTE FOR HOME ASSISTANT USERS: Versions of Home Assistant prior to 2025.01 are no longer supported as of this build. They may continue to work, but no effort will be expended to maintain compatibility going forward.

• Rules: New Script condition -- write an expression (simple or complex/compound) that returns a boolean (true/false) or null, just like any other condition. The alarm() function works in it, too! And it holds more secrets... see docs WARNING: This is a "bleeding edge" new feature; it may be subject to breaking changes as it evolves into final form.
• Expressions: Add new print() function to assist troubleshooting of complex expressions.
• HassController: Support for new HA selector/data type in input_datetime entities and other similar.
• HassController: Versions of Home Assistant older than 2025.01 are no longer supported, as support for a number of (their) deprecated features and functions is about to end.
• HassController: Bless HA to 2025.11.1

[CatmanV2]

@toggledbits that looks like a massive leap!
