Another approach that scales even better: EventTrigger.
I just set the channel and nothing else.
I connect the copied Notif command to the DrvHttpNotif device.
After changing the channel, an event appears, and in the ACM log I see:
2025-12-04 21:57:45 Send command. Device 200, command Notif
Unfortunately, nothing happens, silence in the DrvHttpNotif device log.
Any idea?

Hi Mikhail,

I was able to get it working with ACM and the phone book – I just need to use the Notif command.
Unfortunately, if I have Channel DataChange Trigger in ACM, it fires after every configuration upload.

Can’t find any doc for this driver. Can you give me a link to this description?

Hi Mikhail,

thank you. I can send an SMS from SCADA with simple “Request” command. It works.
Now I want to use it as notifier. So I have some contacts in the address book.
I have Channel Data Change Trigger in ACM.
How to connect this together? Command to device DrvHttpNotif? But how to access this address book?

I made it work.
I created a proxy service that accepts POST requests and sends SMS messages with two-factor authentication based on them.
Since the request is in JSON format, I have to use [param] instead of {param} for the parameters.
The Headers tab probably refers to the response, because when I set Content-Type there, I kept getting the error: “Error creating request: Misused header name, ‘Content-Type’. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects.”

I will send something like: {CnlName} on {EvDev} at {EvObj} changed value to {CnlVal}

I suppose this should be Channel Data Change Trigger and than Command with code “Request” to my Notifier device.
Now is the question: how to send SMS to a recipient from the address book?

One more request: could you remove the phone number from the configuration I sent? I can’t edit my message.

<?xml version="1.0" encoding="utf-8"?>
<NotifDeviceConfig>
  <Uri>http://localhost:5150/send-sms</Uri>
  <Method>Post</Method>
  <Headers>
    <Header name="Content-Type" value="application/json" />
  </Headers>
  <Content>{
  "phoneNumber": "+486011111",
  "message": "SCADA"
}
</Content>
  <ContentType>application/json</ContentType>
  <ContentEscaping>EncodeJson</ContentEscaping>
  <ParamEnabled>false</ParamEnabled>
  <ParamBegin>[</ParamBegin>
  <ParamEnd>]</ParamEnd>
  <AddrSep>;</AddrSep>
</NotifDeviceConfig>

Is there a possibility to simply test if this solution works?
If I had the service which works like:

Invoke-RestMethod -Uri "http://localhost:5150/send-sms" -Method Post -Headers @{ "Content-Type" = "application/json" } -Body '{"phoneNumber":"+48111111111","message":"Test API"}'

and put Url into DrvHttpNotif with content type json and so on. How to send a test message?

[oley]

Thank you,
yes I will provide simple proxy service which can become single request and make two-factor request.

Hi, got it! Thanks!

Hi,

I can not set the undefined icon.
Status channel equals 1 (and every positive) shows error icon, 0 and -1 (or any negative) shows normal.

Hi,

Thanks, got it.

Hi,

I figured it out.
Thanks!

Hi,

I tried this at the beginning, but it also does not work and additionally shows this directory structure in the tree view:
..
..
..
custom
MyPage

Can this custom page be located in the project directory structure, or must be in SCADA program files directory structure?

Now I’ve got this simple html in the views/Weather directory in my project, but dashboard show only blank field.

[oley]

Hi,

I figured it out myself before I read the answer. Thanks!
