I need a handful of victims volunteers to help test previews of the next build of Reactor. A long-standing request was for "a simple login mechanism," but in practice, adding user authentication and competent access control turned out to be a pretty big project with a lot of big changes on both server and client sides. It's a bit more than I'm comfortable testing myself and springing out to everyone at once, so I'd like to work with a small group to put it through "sea trials."
Major changes/features include:
User authentication with hashed password storage; User group configuration with application restriction (admin, dashboard, API); Detailed control over API access, with user- and token-based authentication/authorization; Improvements to the HTTPS service; Improvements to UI coordination with the core for Rules and Reactions.If this sounds like something you'd like to help with, drop me a reply here in this thread or privately.
I have a case where I'm trying to send a MQTT message similar to the example below:
Topic: pool/set { "command": 4, "value": 1, "time": 0, "interval": 0 }But I need to set "value" so that it is an integer between 20-30. I thought I could use "dimming" capability here, but there's probably a better way. @therealdb ?
(Using userauth-24120-7745fb8d build in Docker)
There's a filtering capability for entities in reactor.yaml, but I have a case where I don't want to filter an entity altogether, but would like to "throttle" it, as this sensor updates every 1-2 seconds (and therefore unnecessarily takes database space).
Sensor data comes through home assistant, and seems that there's no way to control update interval at that end.
So I'm asking if plugin configuration could support limiting/throttling updates for certain entities?
Good morning,
Hopefully this is a simple request. I believe the title should be self explanatory, but just in case, I'll elaborate.
On the status tab, we all get alerts if a device state has changed (i.e., been removed). This is great, but when I go into the entities tab, I have to either type the name (or a portion thereof) of the device that has been removed, or I need to scroll all the way through my list of devices. This is infrequent, however, yesterday I replaced a failed device in my HAAS environment. It was a Z-Wave switch that is added using the Smart Scan QR code, which normally makes it pretty easy. However, some devices don't get fully added the first time around, so it'll add multiple entries into HAAS until it get's the S2 authentication correct and the device fully included. It did this to me yesterday, and I had to delete the incomplete device from my installation. MSR still saw the entities of that failed/incomplete switch entity, and I was left with 8 alerts and entities that I needed to removed.
It's not a huge problem, but this example was just one switch. If I were to add replace multiple devices at once, this could be a bit more annoying to remove. It would be helpful to be able to filter by removed entities, so I can find them all quickly and delete them. Continuing that train of thought, it would also be useful to have check boxes next to those lines, and perhaps do a select all type of thing so they could be deleted in one mouse click.
@toggledbits I have finally finished up the SSL using Let's Encrypt and am getting this from my local browser:

I know you said in the docs that using a self-signed could lead to this but this is LE.
Hi @toggledbits,
I don't know if I'm the only one, so I'm reporting here first instead of opening a bug.
Basically, with the latest 2-3 updates of Reactor and MQTTController, after a restart previous statuses are lost (for both Virtual and MQTT entities), until they're restored.
It's particularly annoying for Virtual Entities, because I have to set them all over again (I've coded some defaults at startup if the values are empty, but sometimes these are not the correct values before the update).
Not easy to reproduce, and logs are gone, but the first time I tought it was me hallucinating, the second one didn't bother too much, after the third I realized it's something not coming from me.
the behavior could be seen in this screenshot:
1c007fc2-4dbc-4476-8dca-e5aa111e4642-image.png
Any hint is appreciated.
Build 21228 has been released. Docker images available from DockerHub as usual, and bare-metal packages here.
Home Assistant up to version 2021.8.6 supported; the online version of the manual will now state the current supported versions; Fix an error in OWMWeatherController that could cause it to stop updating; Unify the approach to entity filtering on all hub interface classes (controllers); this works for device entities only; it may be extended to other entities later; Improve error detail in messages for EzloController during auth phase; Add isRuleSet() and isRuleEnabled() functions to expressions extensions; Implement set action for lock and passage capabilities (makes them more easily scriptable in some cases); Fix a place in the UI where 24-hour time was not being displayed.I'm slowly migrating all my stuff to MQTT under MSR, so I have a central place to integrate everything (and, in a not-so-distant future, to remove virtual devices from my Vera and leave it running zwave only).
Anyway, here's my reactor-mqtt-contrib package:
Contrib MQTT templates for Reactor. Contribute to dbochicchio/reactor-mqtt-contrib development by creating an account on GitHub.
Simply download yaml files (everything or just the ones you need) and you're good to go.
I have mapped my most useful devices, but I'll add others soon. Feel free to ask for specific templates, since I've worked a lot in the last weeks to understand and operate them.
The templates are supporting both init and query, so you have always up-to-date devices at startup, and the ability to poll them. Online status is supported as well, so you can get disconnected devices with a simple expression.
Many-many thanks to @toggledbits for its dedication, support, and patience with me and my requests 🙂
Good morning,
So Home Assistant decided to change the default weather home format that I've been using for the past year and a half. I had two Global Expressions set up to pull the high and low temp forecast for the day. Now it's pulling null values.
094c9205-cc9e-4fcc-ac4f-1bf54acea299-image.png
In the dev tools, it now uses a new service (Weather. get forecasts), plural, where the old Weather.get forecast is depreciated and now longer functions.
8c7a1fcc-dd3f-4268-a0b7-29d542f86adc-image.png
It shows a templow field, and a temperature field, which I presume is the forecast high.
When I head back over to MSR, I'm having a hard time finding those values in the Entities tab.

MSR: latest-24057-e9add9f5
Hey Patrick, I recently have been noticing that MSR has been acting up ie. it's been needing restarts and has been slow. I began trouble shooting by looking at the logs and have noticed the following errors for a lot of entities. I thought maybe a simple reboot of RPi was needed and I kept seeing the same errors in the system logs. I am oddly enough not seeing these same errors in the MSR logs. Where things started getting weird is whenever I rebooted MSR it wouldn't come back online .I would have to restart the RPi then it would come back online. I just restarted MSR again to capture logs and it restarted fine, so I guess its good for now? I think this is more or so a corrupted SD card issue rather a MSR issue but well being troubleshooting from here. The SD card is about 1-2 years old.
Apologies if this post is everywhere, I cannot consistently recreate any oddities that are happening, that's what is leading me to believe my SD is going bad.
PS: If anyone knows how to diagnose a corrupt SD card please chime in.

This system has been running flawlessly year after year for the time changes twice a year literally since MSR came out so I was caught off-guard when this happened this morning.
Time in MSR browser is EST, time on RPi is local time (DST).

What am I missing here @toggledbits ?
Hi,
For the standard capabilities MSR sends both a value record and a units record to InfluxDB. The latter I would like not to send as they are not really any use for me and it will reduce the number of records send to my InfluxDB.
Is there a quick way to do this with a filter_entities line like: *>units?
Or do I have to update all capabilities to read like this:
power_sensor:
attributes:
value: true
Cheers Rene
I'm trying to replicate this
wallbox_set_number.PNG
into a MQTT entity where I could set a number with a min and max value.
I can't find a standard capability that fits or any documentation on local MQTT capabilities and the only post on the forum mentioning local MQTT capabilities is this post, is it even possible in current release?
My trial and error work in local_mqtt_capabilities.yaml isn't much to show as it's just a copy of mqtt_capabilities.yaml with changed names and then I got stuck.
Any guidance, examples, documentation, future feature request or denial would be much appreciated, thanks!

Hi guys,
I've recently bought a new Govee outdoor permanent lights set, and I love it. WAF is pretty high, and the product is good quality. I hope to never run lights in the front of the house.
This new addition has found me searching for something to control these lights, locally. Govee has officials remote and LAN APIs and Home Assistant has it supported, but some undocumented stuff that's integrated into an Homebridge plugin that seems very promising. Without this plugin, my playlist is orchestrated via the cloud and that makes zero sense.
In the past I got some inspiration from plugins running on other platforms and Homebridge seems one of the most active. I could map its devices via HomeKit-local on HA, but I've decommissioned Homebridge years ago when we settled to Alexa (and I want to stay simple), so I had an idea: why get inspiration and rewrite things, when you could write an Homebridge adapter that could load any Homebridge plugin and run them natively under Reactor (MSR)?
I'm not sure if that's viable or made any sense, so I'm posting here to get feedback, encouragement and your thoughts. Anyone could be potentially interested in such a thing?
Hi- looking for a hint in where to start. My goal is to set a PIN code in a zwave kwikset lock triggered in a rule.
The device isn’t exposing methods to help. The x-hass.call-service looks promising, but what would the service name be?
Plan b would be send the zwave controller a config command- I don’t see any way to explicitly send a command through JS Zwave in my environment.
Running reactor bare metal. JS Zwave is running as an add on inside HASS OS.
Any tips are appreciated.
Hey crew, I'm trying to use MSR to control the RGB values of a Z-Wave bulb in Home Assistant.
Problem I'm running into - I would like to use 'rgb_color.set' to control this, but it doesn't work, instead it always passes the values '255,255,255' to HA no matter what values I enter within MSR.
More notes and examples below - I'm wondering if this is a formatting issue that I'm missing? Thanks for any help!
NOTES FROM TROUBLESHOOTING:
'rgb_color.set_rgb' works successfully, which seems strange. You'd think they would both be affected I've tried a couple different formats, like adding quotes, adding/removing spaces between the RGB values, nothing has fixed it.EXAMPLES:
When I use 'rgb_color.set_rgb', the values successfully carry over to Home Assistant:

I’m running MSR in a docker container on my Synology Nas. The container is automatically updated using watchtower weekly.
It was working. Now, after the update, Reactor webpage is able to load, and all indications on the webpage suggests that it is working fine. However, the updated statuses from Home Assistant and Vera are not being detected.
The container logs show the following error

Noticed right away last night at closing time that the open/close had become inverted with the update to v23326.
It wasn't an awful bit of lift to change all Reactions to reflect the change but it was jarring initially when everything flipped.
Are there release notes on that version, @toggledbits ?
Expressions and LuaXP Functions
-
@toggledbits said in Expressions and LuaXP Functions:
The result of push is an array.
But if you
push ( [ ] , 1 )
shouldn't you get
[ 1 ]
? And not[ [ 1 ] , [ 1 ] ]
? -
It depends on what the complete expression is. Remember that the value of
each
is every non-null expression result during the iteration. So an array of arrays is a very possible response. -
@toggledbits Unless I'm mis-reading the way
each
works, I had anticipated the underlying interpretation of:b=[],each i in a=[1,2]: do push(b,i) done
to be as follows:
"Start with an empty array namedb
. For each item in the array nameda
, starting with1
, append that value into arrayb
. First, you would get[ 1 ]
, and the next iteration, using the2
froma
, append that tob
to yield[ 1 , 2 ]
."Any I missing an important piece of the puzzle? (I do recognize that
do
/done
is not necessary here, but I left it in for direct comparison with the expression immediately preceding.)Thanks. Sorry to give you grief over these operations.
-
If you want to see what b looks like at the end, you need to do this:
b=[],each i in a=[1,2]: do push(b,i) done, b
If you don't (which is how you've done it so far), you are seeing the result of
each
, which is an array, and since each expression within theeach
has resulted in an array, the result of thateach
is therefore an array of arrays, and referring to the same array by reference. -
This one seems to evade the purpose of
isnull()
somehow:isnull(1/a) // returns false
whereas
isnull(a) // returns true, as expected
In both cases,
a
is undefined.I also cannot seem to create an expression that results in true for
isNan()
, no matter what I throw at it.Finally, why would
bool(null)
return TRUE? -
null coerces to zero (0) for arithmetic operations, so
1/null
is infinity which is not null.int("abc")
results in NaN which will returnisNaN(int("abc"))==true
bool(null)
should return false and I will fix it.Edit: just to follow up, I've added
Infinity
as a keyword/value to the grammar, with a supportingisInfinity(value)
test function (you can also test viavalue === Infinity
), and added that to the documentation for the next release/build. Andbool(null)
is fixed. FYI,bool()
takes a slightly deeper view of "truthiness" than JavaScript natively: the values (number) 0, null, empty string ("") and NaN are false as in JavaScript, but so additionally in lexpjs/Reactor are string "0", string "no", string "off", and string "false"; any other value of any type is true (including empty arrays and objects). -
MSR RECIPES: Compact object-based message composer
Several of my Rules send out SMTP emails, and I'm always looking for a compact method of composing these outbound messages, using the fewest expressions along with a simple "mail merge" template. Here's a two-variable approach you might consider:
msgBody ► "This is my message." // leave blank if msgBody will be set by other Rules msgTemplate ► tmp = {hdr:"Header here" , msg:msgBody , ftr:"Footer here" , crlf:"\n"}, send = {message:tmp.hdr+tmp.crlf+tmp.msg+tmp.crlf+tmp.ftr} , send.message
I hope this can be adapted to your workflow somehow!
-
Can someone please explain how you would create an array within a Rule that does the following:
(a) begins with an expression that is an empty array;
(b) has another expression containing the .dim_level of a given light;
(c) each time the Rule sets (activates/triggers), the value of (b) is pushed into (a)Working example:
First time light gets turned on, the rule runs. Dim level of 50 is pushed onto end of [ ], making it [50].
Next time light turns on, the rule again runs and pushes the dim level of 75 onto array, making it [50,75].
Etc.I can't quite grok where to put my
push ( )
. In a[Set Variable]
using${{ }}
substitution? In an auxiliary Expression? (I've attempted this approach and can only get one iteration along, meaning the array stops growing after 1 element.) And how does one declare an empty array inside an Expression that will otherwise be modified by the Rule, which normally requires it to be blank?Thanks!
@toggledbits , to put this more succinctly, I find myself unable to implement in MSR the construct you laid out here for creating a time series.
-
SOLUTION: This works for creating a timed data series in MSR...
test1
:= if go=="1" then push( test1 , getEntity( "vera>device_110" ).attributes.dimming.level , 5 ) else test1 endif...BUT...you must first pre-populate thetest1
variable with an empty array[ ]
,SAVE
, then paste in the above definition. Otherwise, MSR will throw a "no such 'push' function on (null)" error! (I call this the "Chicken and the Egg" conundrum, whereas Reactor for Luup doesn't complain about doingpush
to a non-existent array; it just invisibly creates one for you.)In my
set
reaction, I do a[Set Variable] [ go ] = 1
, and in thereset
reaction[Set Variable] [ go ] = 0
, with anInterval
imposed on the Rule's sole Trigger condition, making it goTRUE
for 2 seconds every 60 seconds.NOTE: Interestingly, with
Interval
limited to 3 repeats, the variablego
changes to"1"
only 3 times (expected), yet somehow the array gets fully populated with 5 values (unexpected), so I must not fully understand the leading- and trailing-edge nature ofInterval
as it applies to Expression re-evaluation. I'm sure @toggledbits will elucidate? Or is this truly unexpected behavior?ANSWER: Unchecking "Force re-evaluation of expressions and conditions" in both the
set
andreset
reactions cured the problem of "too many data points". There was my problem. -
@librasun said in Expressions and LuaXP Functions:
you must first pre-populate the test1 variable with an empty array
You don't actually. This is just a bug in lexpjs. I've fixed it in my local copy, will be in the next build. It's just this simple:
-
@toggledbits Do you want to include conditional key references like this in lexpjs?
obj={'122':['a',5, true]}
obj?['123'][0] // null or throws error
obj?['122'][0] // (string) "a"By this I mean do you want to have square bracketed key references treated the way potentially non-existent dot references are handled using question marks.
-
Confused. Are you asking for this to be added?
-
I think so, if it's possible. Just wanted to (a) make sure that ?[ doesn't exist yet (my testing seems inconclusive), and (b) you consider it necessary. I've already bumped into a potential use case.
So, I suppose "Yes, add it" at least for consistency with existing ?. usage.
-
@librasun OK... so I think I'm seeing through the confusion now...
The
?[
and?.
operators already exist; they were added together with??
a long time ago. They are left-associative, so they refer to the operand on the left. In your examples, they will not work as you are trying to get them to becauseobj
is non-null in every case (it's the first thing defined in the example). I think what you mean to say is:obj={'122':['a',5, true]} obj['123']?[0] // which will return null and not throw an error obj['122']?[0] // which will return (string) "a"
-
Agree with everything you just wrote. I was mis-applying the question marks, as far as placement in my expression (treating it as a prepend instead of append). Thanks for straightening me out yet again.
I had mistakenly thought this construct only worked on
objects.?with.?arbitrary.?keys
and arrays[with_arbitary_indexes]? and notobject
keys (with non-standard names) referred to via brackets. My bad. -
CODE SAMPLE: Creating an Array of N Whole Numbers [0, 1, ... , N]
Sometimes you need an array of Counting Numbers from zero to some arbitrary integer N. But it's hard to write this as an Expression in MSR, because you don't know in advance how long to make the array, and the value of N may change later.
This somewhat byzantine construct fills the bill, and works for N=
0
up to N=56
:arrCount := N=56,each s in keys(substr((s='s'+1/9)+s+s,0,N+1)): int(s)
This example evaluates to the array:
arrCount == [0,1,2, … ,55,56]
Just change the number after
N=
(it could also be another variable name, of course!) to suit your needs.BONUS: Need more numbers? Just add another
+s
in the middle for an additional 19 integers (giving max. N=75). Repeat indefinitely!P.S. @toggledbits I may need to enter this in the Obfuscated Lexpjs Code contest!
-
I think it's a grand prize winner for the "Solutions for Problems Nobody Has Ever Had Using Reactor" contest, for sure, but I'll admit it's not a straightforward problem to solve without a counting loop structure, so the question is, what's the best approach:
- Implement a counting loop statement (
for
in many languages); - Take the Python-ish approach and have either a
range()
function or astart..end
range operator, which you could use as the operand ineach
; - Other?
Choice 2 is better suited to an expression environment, but we already ride the fine edge with
each
,first
anddo
statements in the current language. But in keeping with the flavor, each of these statements still produces an expression result, so still arguably as much operator as statement; it's less clear what a sensible return result from "for" might be. On the other hand, #2 requires an array be built in memory over which to iterate, and an error could easily build a large array that consumes dangerously large amounts of (or all) available memory and have a negative impact on stability (so perhaps more safeguards in order, but how big is too big?).EDIT: I just prototyped the two options given above:
# Example for to build array of values 1-25 arr=[]; for i =1,25: push(arr, i) # That's unnecessarily clunky and could be streamlined by making "for" return an array # of result values like "each": arr=for i=1,25: i # But then... that means "for" is about the same as "each", just different operands. # In my mind, that kind of argues for option 2: arr=each i in range(1,25): i # or arr=each i in 1..25: i # and even that's unnecessary, because you could just do arr=range(1,25) arr=1..25 # because both of those naturally return an array. # Another example, to sum all the values from 1 to 25 it would be: sum=0; for i in 1,25: sum=sum+i sum=0; each i in range(1,25): sum=sum+i sum=0; each i in 1..25: sum=sum+i
I think the range operator
..
is the cleanest all around, and relieves the ambiguity of having bothfor
andeach
so similar. I'm not sure..
is any easier or harder to learn/remember than having a functionrange(start,end)
. So I'm leaning toward option 2 with range operator..
