I'm only trying to add this bit:

  - id: mqtt
    name: MQTT
    enabled: true
    implementation: MQTTController
    config:
      # Replace IP with that of your MQTT broker below
      source: "mqtt://127.0.0.1:8883/"
user: something
password: something

Although the user and password are correct, I'm not clear if I need to quote them or not. Restarting reactor with that in my (otherwise working) reactor.yaml: Reactor stops and just sits there, logging nothing. (Not checked the Mosquitto logs yet)
If I swap reactor.yaml back to a working version reactor starts fine. So it's got to be something real easy.....

@catmanv2 I am no expert but try this:
Change user: to username: Also, I believe both username: and password: should be the same indenting as source.

Thanks. username makes no difference. Does the indenting really matter? If so I shall have to get some code editor as vi isn't letting me get it right

Yes, indenting matters, like @therealdb said previously.
Is port 8883 the correct port for your setup?

Lovely, ta. I shall fire up VS code! 8883 is correct as well

Yes! YAML is highly dependent on indenting! And you must use spaces, not tabs. Here are a few good YAML tools on line to help:

• https://yamllint.com - Check YAML (paste and click)
• https://yamlchecker.com - Another checker
• https://onlineyamltools.com/edit-yaml - A handy web-based syntax-driven editor

[CatmanV2]

Wow. Thanks ever so. Binned the sample code for the Owntracks manual and 'handcrafted it'. First time

<edit: re reading, it's not clear that at this point Reactor happily started and now shows the MQTT entity, so problem solved>

[therealdb]

@catmanv2 not a fan of yaml, but I agree it’s easier than json or xml. but the indentation sometime drives me crazy, and the tools suggested (or vs code) are useful to double check the files.

[CatmanV2]

@therealdb VS code saw nothing. Yamlchecker picked up an issue, but even with that corrected, it didn't work <shrug>

Now does anyone have an Owntracks template?

Otherwise this is going to be a steep curve I suspect

Three words that should never be written into a post asking for help. At least, as I've often said, not as the entire summary of where you are. I suggest a form more like this (the numbering is just to separate component parts of your question/post):

"OK, It didn't work. Here's where I am with this darned thing..."

1. Describe what part/thing you are trying to do; if part of multiple step process, tell us both what you are trying to do overall, and what step of that process you are working on that is going wrong

   "I'm trying to get my MQTTController instance in MSR to connect to my broker, and I need to use a username/password for authentication. I have configured the username and password in my reactor.yaml file."

2. Describe what you expected to see.

   "When I restarted MSR and hard-refreshed my browser, I thought I would see the MQTT system entity in the Entities list, or the controller listed as "up" on the Controller Status widget on the Status page.

3. Describe what you actually see (e.g. errors or exceptions) or what you don't see that you expected. If there's an error on the screen, make sure your narrative includes the full and complete text of it, and describe where it came up and what you were doing when it did. If it's a corrupted display or something better shown with a screen shot, add that behind your narrative.

   "The MQTT controller doesn't show up at all in either the Entities list or Controller Status widget."

   ... or maybe it's worse than that?

   "Reactor doesn't even start now."

4. Show your work. Give the problem context.

   "Here's what the configuration section for my MQTTController instance looks like when it fails:". Paste the text of the configuration from first line to last without redaction or modification except passwords/access tokens/private keys[1].

5. Show that you dug for an answer yourself:

   "I looked in the logs, and found these messages:" — follow with snippet of log, with one or two dozen lines of context before what you found. Never post just an error message without context.[1]

   In many cases, this last step will lead you to answering your own question. If you can't interpret what you are seeing, that's perfectly fine, but we need to see it to help you, and there's no point in making us ask for it. Go look for it yourself, and give it up front.

Give us something to go on. Messaging back and forth in a forum like this is the worst way to play "Twenty Questions". The less detail you give, the longer it takes to get a solution. And the old Internet trope of the 2000s is still true in the current decade: "People will put as much effort into answering your question as you put into asking it."

IMO, the posting guidelines I wrote for the Reactor category here (which are based on posted guidelines created for Home Assistant's forums, which are based on guidelines created elsewhere) should be applied everywhere. It's in your interest.

---

[1] Formatting code and log snippets should be done using the ``` sequence on a line by itself, followed by the code or log snippet, followed by the ``` sequence on a line by itself again.

```
controllers:
  - id: mqtt
    name: MQTT
    implementation: MQTTController
    enabled: true
```
looks like this when your post is later displayed (which is helpful/necessary for readability and finding errors in YAML in particular):

controllers:
  - id: mqtt
    name: MQTT
    implementation: MQTTController
    enabled: true

(@CatmanV2 , you clearly know how to do this formatting, I'm just adding this for completeness/benefit of future readers).

OK, fair shout but it was more a comment of 'It didn't work then'. (Not withstanding the rest of your valued guidance) I am no longer asking for help (on that issue), nor was I when I made that post. Because It was, buy that point, working.

[toggledbits]

OK. That wasn't clear to me. It seemed like you were still having issues. I am, in any case, glad to hear you made progress.

What step are you on now? Have you made your broker accessible on a public IP and port?

[CatmanV2]

Yes, thanks.

I can see Owntracks connecting, and also Reactor is happily showing the MQTT Entitiy. So I think that all the connections are there. The next step for me would be to get the correct configuration for Reactor to, well, react to an Owntracks message.

My only request is if anyone has an Owntracks / YAML template for reactor (which is what I think I need next) that would save me from trying to create a new one....
....which I will cheerfully do once I've read a lot more about documentation and so on.

Cheers

Here's a simple config for a binary sensor that is true when I am home (i.e. in the region called "Home" in Owntracks):

      entities:
        owntracks_patrick_home:
          name: "Patrick Home"
          capabilities: [ binary_sensor ]
          primary_attribute: binary_sensor.state
          type: BinarySensor
          events:
            "owntracks/user/phrs21":
              "binary_sensor.state":
                json_payload: true
                if_expr: "payload._type == 'location'"
                expr: >
                  ( first region in ( payload.inregions ?? [] ) with region == "Home": true ) ?? false

The capabilities and primary_attribute set up the entity in Reactor to hold the interpreted payload data from Owntracks' location updates. In this case, we're just going to keep a binary in/out state for the one region, nothing else.

The event configured here reacts to an incoming "owntracks/user/phrs21" topic/message (phrs21 is set in the Identification part of the connection configuration in the Owntracks app). When that topic comes in, we declare that the attribute binary_sensor.state is going to be modified according to the expression given. The json_payload: true line tells MQTTController to interpret that payload as JSON data and make a proper object out of it that the expression can then pick through easily. The if_expr expression makes sure that the assignment to the attribute is done only if the payload type is location (there are several message types that may be sent, not all of which contain region data). The expr expression itself accesses and loops through the inregions array of the payload (now object) to see if Home is an element of the array, and returns true if so. Otherwise, the expression returns false (i.e. not home). That result is assigned to the binary_sensor.state attribute..

Some details:

1. The expression fragment ( payload.inregions ?? [] ) is using the coalesce operator ??. If inregions does not exist in the payload (i.e. you are not in any region), the payload.inregions reference would result in null, so the coalesce replaces that with an empty array ([]). This prevents the expression from throwing an error if inregions is missing/null.
2. The ending fragment ?? false is a similar use of the coalesce operator because, if "Home" is not found in inregions, the first..in statement will return a null (which is what it does when nothing matches). Using the coalesce converts that null into a real false, indicating that we didn't find "Home" listed and we are therefore surely not Home.

Edit: added if_expr in the config, and explanation in the narrative.

[CatmanV2]

Thankyou, sir!

[toggledbits]

Also, I've just added this as a template called owntracks_in_region to build 22260 of MQTTController.

[toggledbits]

FYI, I revised the config and the narrative to make sure it doesn't try to update the sensor for message types that would never contain inregions (and thus could cause the binary sensor to spuriously go false).

[CatmanV2]

I'd like to add further regions for Owntracks. Would the reactor.yaml look like this:

        rachel_iphone:
          name: "Rachel Phone"
          topic: racheliphone
          uses_template: owntracks_in_region
          regionName: Home
          user: xxx

Would I need to duplicate everything in the above, with the different regionName? or just the last two (or three) lines?

TIA

C

[CatmanV2]

Wow. Apparently yes with a different entity name (durr)

Quite pleased with myself that I also managed to not screw the .yaml!

C

[toggledbits]

I'm sorry, I read this thread yesterday and got busy with (non-HA) stuff all day and never got back to it...

You are correct... new entity ID, new entity name, change the region name as needed, good to go.
