Three AC units connected via Wifi kit

Developer Programs Support
1

A user has three AC units connected to a Wifi kit. The API lists just one AC unit with the name of the master unit in the SmartThings app, plus the normal capabilities, but it doesn’t show the individual units like the SmartThings app does.

  "items": [
    {
      "deviceId": "",
      "name": "Wifi-kit",
      "label": "SB12 Air-con",
      "manufacturerName": "Samsung Electronics",
      "presentationId": "DA-AC-SAC-100001",
      "deviceManufacturerCode": "Samsung Electronics",
      "locationId": "",
      "ownerId": "",
      "roomId": "",
      "deviceTypeName": "Samsung OCF Air Conditioner",
      "components": [

How can I get the details of the individual units and control them via the API?

Hi, @AdyR
Could you provide the following to get more information about this case, please?

  1. Model of your AC Wi-Fi kit
  2. Confirm the email account registered in the forum is the same one you use for SmartThings. If not, please share it with me over DM
  3. Enable support access to your account:
  1. Go to the SmartThings Web (my.smartthings.com)
  2. Log in to your Samsung Account
  3. Select Menu (⋮) and choose Settings
  4. Toggle on Account Data Access
  5. Select the time period and confirm - In this step, please select “Until turned off”, once the team finishes, we’ll let you know so you can disable it again.

Hi @nayelyz, thanks for getting back to me so quickly. Unfortunately, the ac units are not in my account, but in a user of my Homey app account. Would it be OK if I get his username and send that to you?

This is an image that he sent to me showing the device in the SmartThings app.

We cannot enter his account if he doesn’t provide the corresponding permissions and we also need the model of the kit to check with the engineering team.
Please ask him to send us an email to build@smartthings.com or you can send the email and copy him there so we’re all in the same thread.

Ok, thanks, I have sent him a link to the topic.

Hi, @Brian.B
Thank you for reaching out! Ok, I see the field of the model is empty for this device, do you have the model shown in the devices kit’s package?
I also see only SB12 Air-con, the physical devices’ name are “Sove”, “Stue” and “Havestue”, right?
This means you have three physical devices but they’re all collected in “SB12 Air-con”, correct?

That’s what I understand. My app only finds the SB12 and sending an on / off command to that switches all three physical devices on and off at the same time. Sending other commands, such as temperature setpoint, is accepted by the API, but does nothing on the physical devices.

Hello,
The model of the wifi-kit is highlighted on the attached picture.
It’s correct that it controls 3 units.

This is from the quote from the installer (2018) showing the units installed:

1 stk Samsung FJM AJ068MCJ3EH/EU (6.8 kW)
1 stk Samsung 1-way kassette AJ035NB1DEH/EU (3.5 kW)
1 stk Samsung MSP Duct MH052FUEA (5.2 kW)
1 stk Samsung HighWall AR12MSPXBWKNEU (3.5 kW)
1 stk Samsung WiFi modul MIM-H03

Danish “stk” means “pieces”

Attached picture shows information found in the app

The installer was on-site a few years ago to replace and update the WiFi-kit unit, as it stopped working.

Hi
Did you hear anything from support?

13

Nothing yet. I will chase up on the forum topic.

@nayelyz any news?

14

Hi, @AdyR, @Brian.B
The engineering team mentioned this is the expected behavior for the Wi-Fi Kit.
The explanation is that only the Wi-Fi kit is registered as a device with its own Id and other communication between the kit and the physical devices happens device-to-device (D2D) among them, that’s why the plugin (in the app) can show it.
I just asked the team if there’s a way to send commands through that main device but it’s highly possible it’s not. I’ll keep you posted.

Hello - any news?

16

Hi! Not yet, I just pinged the team again.

17

Hi, @AdyR, @Brian.B

The engineering team confirmed there’s no way to control the other devices through the main one we see in the API.
If you send commands to the capabilities of the main device, for example, to turn on, does it turn on only one device?

18

Hi
All 3 units are turned on unfortunately

ooh ok, sorry, unfortunately, there’s nothing we can do to change the current behavior.
You could contact Samsung, who is the manufacturer, to request a change in how it was implemented if possible, and see what they say. I don’t actively suggest this because I’m not certain you’ll get a positive answer.

Thank you for looking into it, sad but helpful.
