I've managed to use MSR UI on iOS devices to some degree*, so that although UI elements (e.g. rule sets) are not visible in portrait mode, you've seen them in landscape. Now with recents builds (24302) this does not work anymore, elements (rule sets, entities) are not anymore visible in landscape mode.
Does anyone have similar experiences? Using iOS 18 and Safari/Chrome browser.
( *Drag & drop of rule conditions have never worked on a mobile)
Hi @toggledbits,
I have lots of logs with this:
<Engine:ERR> Assignment to alarm ignored -- expression-driven global cannot be set by assignmentAny hints to where look at to avoid this? Thanks.
Hi @toggledbits
I'd like to update my controllers with these new features, but I'm struggling to find any guidance in the docs - and in general to understand the context.
Could you please elaborate more? Thanks.
I have the following ACL defined:
groups: admin: users: - admin applications: true api_acls: # This ACL allows users in the "admin" group to access the API - url: "/api" group: admin allow: true log: true # This ACL allows anyone/thing to access the /api/v1/alive API endpoint - url: "/api/v1/alive" allow: trueAnd I have authenticated to MSR as "admin" user. However, I'm getting "access denied" when trying to access http://*******:8111/api/v1/log
So what I'm missing, is my ACL incorrectly defined?
Using build 24302 on Docker.
Thanks to @toggledbits for adding a custom CSS. I've started doing a darker Reactor style.
Here's the file: https://gist.github.com/dbochicchio/825098ac13b7f8cac22012eae37ff7ce
A couple of things are still too bright and I'll eventually catch-up. Just place it under your /config directory, naming the file as customstyles.css. Hard refresh your browser.
Hi!
In Home Assistant I sometimes uses the TTS, either to my Sonos or Google speakers. With reactor in Vera I also use TTS.
But in MSR I can't select the TTS-service. It's simply not there. Am I missing something, or is this the case, so far?
Thanks!

Hi
I have just connected a bunch of EzloPi controllers to MSR to import some ESP based devices etc.
They all seemed to have worked and imported in to MSR apart from I have one missing device. It is a Digital Gas Sensor device.
This is how that device looks in the Ezlo API.

They have an EzloPi website here you can create your own sensor projects using ESP boards, which is very interesting stuff!
And I just wrote on the Ezlo forum here, how to connect an EzloPi controller to MSR.
THANKS.
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.A couple of things for you @toggledbits, since you mentioned that this release has new features and some tweaks are expected.
Local expressions cannot be deleted. Pushing the X button has no effect for me.
When cloning an entity action, the result is strange (first is cloned one, second is the original action):
a92ea094-9e2c-4aaa-bf47-2d07a6ffdbd0-image.png
When changing the action on the cloned element, the params are added to the original one. See screenshot:
92ac3011-83c8-466b-bd23-47d483ad7a52-image.png
Dark theme has a couple of strange contrasts. One is visible in the previous screenshots (white text on yellow background). Another one is in groups (blue text on blue background):
9b3c4988-53ef-44e6-9672-30e744cacb75-image.png
Overall, I found blue, yellow, red and green (in buttons and forms) to be too bright.
On the bright side:
I love the new script action: thank you! The dark theme is a great start to avoid getting blinded at night I promise I'll try very soon the new features around actions. Thanks!@toggledbits
I just upgraded to version MSR 24293, bare metal running on Fedora. Upon restart, I am getting a error banner:
I followed the new directions about npm
npm i --no-save --no-package-lock --omit dev
Any idea what the issue is?
Seems like switching the UI to the newly added dark mode (thank you for this) does nothing. The UI stays in light mode and only a few buttons turn into dark mode (see screenshot)

Good morning,
I have a service MQTT service that needs a restart occasionally. The add-on (Smartbed MQTT) is for the smart bed base for my bed. It has a "safety light" that I can control from HAAS & MSR as a light entity, and also moves the head of the bed to a preset at bedtime, and then lies it back flat in the morning The problem is, from time to time, the light becomes "unavailable" Restarting from the Add-ons tab in HAAS always fixes it, but I should be able to detect when it happens when "light.tempur_pedic_safety_lights" is not true or false, i.e., unavailable.
What I don't know how to do is how to restart that service. Does anybody have experience in restarting add-ons from MSR?
Running:

RPi5-64 (8GB) Core 2024.7.3 Supervisor 2024.08.0 Operating System 13.0 Frontend 20240710.0Hi!
Is it possible to generate two additional log files, the first being the replica of what is displayed on screen by the Rule History widgets and the other with Recently Changed Entities?
And could I configure the generation of one file per day, and delete the older ones? For example, store the last 5 days?
And being more ambitious, does Windget have an icon to open these TXT files in the navigated?
Well, we're approaching Christmas, so here's my request to Santa Claus @toggledbits 🙂
Hi @toggledbits
I'm working on a controller to generate llm response from a prompt in reactor. I have http response coming thru an http request action at the moment, capturing the response inside a local variable. So, it's practically sync.
I want to create a controller, so I don't have to rely on a proxy (and have a simpler architecture), and duplicate absurd http actions, but AFAIK in the current implementation, actions are async only. But if I have multiple requests going on, I cannot be sure what it's really inside an attribute. I also thought that something like a correlation id when sending the request could be used to identity multiple responses, but I wanted to double check with you before starting with something too complicated. I also noticed that some actions in home assistant (ie forecast) are sync and I'm wondering if you have any plan or hint to address this situation. Thanks.
Thanks.
@togglebits I am curious as to why the tilt_sensor.state (primary) = NULL. I believe it should show true or false. I have to use binary_sensor.state instead in my rules.
Again, not sure if this is related to Reactor/ZwaveJSController implementation or the actual Z-Wave JS UI docker version. I have copied, below, the attributes of the tilt sensor in hopes it can help.
Thanks in advance.

@toggledbits I have noticed after upgrading both Reactor and ZWaveJSController to version 24257 that two of my devices/entities, TILT-ZWAVE2.5-ECO and Zooz ZSE18, had their entity re-named in an unusual way and also appears to be duplicated.

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 🙂
[Solved] latest-22328 restart fails
-
Solution: An update to openLuups MQTT implementation on handling acknowledge packets for QoS > 0 solved this issue.
EDIT: Seems related to any restart without any configuration changes. If I revert to 22310 I can restart Reactor from UI and with systemd within seconds, but with 22328 it fails to restart., both from UI and systemd. I have to stop the service and then start again.
I tested to comment out my http (not https)?baseurl
in the config on my bare metal Ubuntu install latest-22328 and triggered a restart from the UI but Reactor would not start after that.
If I uncomment the key and restart the service, Reactor comes back to life.
Is my setup an exceptional circumstance or is this only applicable on new installs -
It's working for me, and I've done some fresh installs of 22328 while testing alternatives to Raspberry Pi (a couple of promising boards so far). I hate to say it, but your post is right on the line of "I tried X and it didn't work for me," so without more detail, I can't really guide you.
-
@toggledbits said in latest-22328 and baseurl [EDIT]: restarts fail:
It's working for me
This is at first all I wanted to know, if anyone else was having the same issue or it's just my setup.
Sorry for the lack of details, I did not know what else to provide as the log is dead silent after shutting down...
I will debug further.
-
Looks like it's related to openLuups MQTT server. The shutdown process hangs after sending LWT to openLuup (MQTTController#mqtt in log).

If I disable that controller Reactor restarts fine as usual.
@toggledbits Is this the moment openLuup MQTT support ends in Reactor or can I change something to make it work again?
@akbooer I've updated openLuup from 22.9.3 to 22.11.22 but no success to this issue.The thing is it's running great when it finally comes up again after a long wait of a forced restart with systemd but it doesn't feel right to force kill the process even though the shutdown process is almost finished.
-
@crille said in latest-22328 restart fails:
Looks like it's related to openLuups MQTT server. The shutdown process hangs after sending LWT to openLuup (MQTTController#mqtt in log).
I think we've seen an issue like that previously. I don't think I see that line in the log you posted?
There may be a problem with retained messages (ie. LWT) and wildcard subscriptions in the openLuup server... I'd have to check.
-
I use a popular package to handle the MQTT broker connection, so I can't see the innards of communications and confirm, but from the rhythm of the log output, it appears that the broker is not sending an ACK to the publish of the LWT; the
publish()
call appears to be sitting there waiting for it. -
Does this mean 22328 require an ACK but 22310 does not? or has something else changed?
-
22310 still required an ACK, in a sense. It didn't wait for it. But because the ACK never arrived, the task in the
mqtt
package also never cleared (they don't have a time-out mechanism), so it just stayed in the queue forever... as did every other topic sent with a non-zero QoS. This actually causes a memory leak that could lead to exhaustion and a crash, because the ACK never comes so the task is never removed from the queue, and those tasks remain and proliferate in the queue.IMO, I think it's fine if @akbooer doesn't truly support QoS levels 1 and 2 in his MQTT implementation just for basic use, but not sending an ACK regardless isn't the right choice, in my view, and it's going to cause problems for a lot of clients that may not be immediately evident (like memory leaks/exhaustion).
-
@toggledbits said in latest-22328 restart fails:
I think it's fine if @akbooer doesn't truly support QoS levels 1 and 2 in his MQTT implementation just for basic use
It only supports QoS 0 .
Nevertheless, the protocol should be respected. AFAIK all PUBLISH requests receive an ACK unless the connection goes down in between times.
-
This is the end of
parse.PUBLISH()
:-- ACKNOWLEDGEMENT -- The receiver of a PUBLISH Packet MUST respond according to Table 3.4 - Expected Publish Packet -- response as determined by the QoS in the PUBLISH packet [MQTT-3.3.4-1] --[[ Table 3.4 - Expected Publish Packet response QoS Level Expected Response QoS 0 None QoS 1 PUBACK Packet QoS 2 PUBREC Packet --]] local ack -- None, because we only handle QoS 0 return ack, nil, TopicName, ApplicationMessage, RETAIN end
Comments to the contrary, it appears it returns
ack
, which is declared butnil
... so... no ACK? -
@toggledbits does Reactor publish it's LWT message with QoS > 0 even though the MQTTController config is at
qos: 0
? otherwise the expected response would be none. -
Yes, it uses QoS 1 (and retain true) because it's a "vital" message. The
qos
you can set in config is for the echo/entity publish functionality; it does not affect other messages. Still, this only requires that the broker acknowledge its receipt (3.3.4), not any delivery, and does not even enforce that QoS on subscribers (3.8.3) -
"The receiver of a PUBLISH Packet MUST respond according to Table 3.4 - Expected Publish Packet response as determined by the QoS in the PUBLISH Packet."
So even though the server only supports QoS 0 it's obligated to send a PUBACK on a QoS 1 level packet as described in table 3.4, correct?
-
Yes, PUBACK for QoS 1, and PUBREC for QoS 2. I don't think that would be a big problem for @akbooer when he gets the time, because all of the information contained in the response can be sourced from the request (i.e. topic, packet identifier, etc.). And otherwise the treatment of the PUBLISH packet can be the same (no further changes beyond sending those ACKs). Not actually having guaranteed delivery behind that is, in my view, an acceptable variance. On the sending side (repeat to subscribers), even though a subscriber may request QoS 1 or 2 for packets from the broker, it still must accept QoS 0 packets (because the requested QoS is a maximum, not an absolute), so everything outbound at QoS 0 isn't likely going to cause problems, especially in this world.
To summarize: if he just provides the PUBACK and PUBREC responses to fix that layer of the protocol, that's good enough. No further actions required above that layer. Not fully compliant (no guaranteed delivery), but at that point, few if any would ever notice.
The other question I don't have an answer for (or I've forgotten; and haven't dug through code to figure out)... @akbooer, does it support retain? If so, what's the storage mechanism, and is it persistent?
-
Well, I must be reading the MQTT 3.1.1 spec all wrong.
When I read:
"The SUBACK Packet sent by the Server to the Client MUST contain a return code for each Topic Filter/QoS pair. This return code MUST either show the maximum QoS that was granted for that Subscription or indicate that the subscription failed [MQTT-3.8.4-5]. The Server might grant a lower maximum QoS than the subscriber requested. The QoS of Payload Messages sent in response to a Subscription MUST be the minimum of the QoS of the originally published message and the maximum QoS granted by the Server. The server is permitted to send duplicate copies of a message to a subscriber in the case where the original message was published with QoS 1 and the maximum QoS granted was QoS 0 [MQTT-3.8.4-6]."
...I understood it to mean that, since I only ever grant QoS 0, then no message would require a PUBACK or a PUBREC.
I realise that this is my bad for writing my own MQTT broker, but it made sense in the context of openLuup, especially in support of Shelly devices which was the reason I did it in the first place. I apologise if this has led to some difficulties, and I'm starting to look at an MQTT validation suite to check out my implementation further. I also realize that Mosquitto is the de-facto standard, but it turns out that having an internal server confers some significant benefits in terms of the internal openLuup architecture.
However, if anyone can clarify the about QoS response issue further, I'm very happy to comply. If a simple fix is to send PUBACK or PUBREC, then I'll do it, but I want to know the reason why. I do understand that the original CONNECT request contains a LWT QoS, per this paragraph:
3.1.2.6 Will QoS
"Position: bits 4 and 3 of the Connect Flags."
"These two bits specify the QoS level to be used when publishing the Will Message."
"If the Will Flag is set to 0, then the Will QoS MUST be set to 0 (0x00) [MQTT-3.1.2-13]."
"If the Will Flag is set to 1, the value of Will QoS can be 0 (0x00), 1 (0x01), or 2 (0x02). It MUST NOT be 3 (0x03) [MQTT-3.1.2-14]."
...but I had assumed that QoS to be overridden by the actual level established in SUBSCRIBE / SUBACK. However, now that I write that, it seems the LWT actually may have a separate life from standard messages?

The other question I don't have an answer for (or I've forgotten; and haven't dug through code to figure out)... @akbooer, does it support retain? If so, what's the storage mechanism, and is it persistent?
Yes, it supports retained messages.
Is it persistent? Not across openLuup restarts.
The openLuup console page: openLuupIP:3480/console?page=mqtt shows all current subscriptions and also (at the bottom) retained messages.

...I understood it to mean that, since I only ever grant QoS 0, then no message would require a PUBACK or a PUBREC.
This section is about your response to a SUBSCRIBE (SUBACK)and what QoS you use to PUBLISH. If you only grant QoS 0 on subscribe, then you will never expect a PUBACK or PUBREC because you never publish anything to a subscriber other than QoS 0.
It in no way limits what a client may publish to the broker, which could include any QoS.
