Add the required number of On/Off Plug Device Type endpoint to the Matter cluster configuration.

Where’s the Matter cluster configuration?

Hi @JGhost-3 ,

Please find the data_model.zap file in products/<your_product>/configuration/data_model.zap, you can edit this .zap file using the ZAP tool, more information here. When you run "Upload Configuration" again, this will generate the updated data_model.bin and upload it to the device.

Please let me know if you face any problems.

Hi @gautam-dev-maker, I'm not sure what exactly isn’t working in the code, whether I use the buttons in the HomeKit app or the physical BUTTONs, the RELAY does not output any signal.

Hi @JGhost-3 ,

I’ve identified the issue and prepared a patch to address it.

Please follow these steps to apply the patch:

• Download the patch file to your local machine.
• Upload the file to the esp-lowcode-matter folder in your Codespaces workspace (you can right-click the folder in the file tree to upload).
• Open the Codespaces terminal, wait for the “Lowcode Is Ready” message, and run:

git apply relay_fix.txt

Or if you’re working in a local setup instead of Codespaces, run the same command from within the esp-lowcode-matter directory.

Once applied run the Upload Code again.

relay_fix.txt

Please let me know if this works!

Hi @gautam-dev-maker, I've tried, but the issue hasn't been resolved.

Hi @JGhost-3, I’ve tracked down the issue — it’s caused by hitting the fixed limit on the number of buttons. I’ve prepared a patch that should resolve it.

Steps to apply the patch

1. Download the attached patch file.
2. Upload it to the esp-lowcode-matter folder in your Codespaces workspace (right-click the folder in the file tree → upload).
3. Open the Codespaces terminal, wait for the “Lowcode Is Ready” message, then run:

   git apply button_fix.txt
   

(If you’re working locally instead of in Codespaces, run the same command inside the esp-lowcode-matter directory.)

4. Once applied, run Upload Code again.

Let me know if this solves the problem!

Hi @gautam-dev-maker! I'm thrilled to tell you that the patch worked! All switches are now functioning perfectly, including both the buttons in the HomeKit app and the physical buttons! Thank you so much!
I have another additional request: Could you help me modify a data_model.zap file to support 20 On/Off Plugs? Thanks again for your help!

[JGhost-3]

Hi @gautam-dev-maker, it's common practice to integrate different products together, but it doesn't seem to support this now. It would be great if your team could improve this.

Hi @JGhost-3,

I’ve created a data model with 20 endpoints and attached it as data_model.txt. You can rename it to data_model.zap and run upload configuration to test.

Thanks for the feedback on lowcode! We’ll work on integrating the ZAP tool with lowcode to make building ZAP data models easier.

Hi @gautam-dev-maker, is it possible to set up 6 light_cw_pwm devices together?
