Hi @kkossev ,
It seems this error is causing my SONOFF SNZB-06P to be shown as UNKNOWN.
Any ideas why the driver is unable to load profile (v4 mmwave) from JSON?
Hi @user5504 ,
Please click on the 'Load Standard Profiles from GitHub' button first :
Do you see any errors in the live logs?
I believe the driver should automatically load the default JSON file upon initial installation... Do you have Hub security enabled, or is Internet access blocked?

Hi, I don't think it is an internet issue.
Driver is able to download the library from GitHub according to the logs.
Try rebooting the hub, will the error go away?

Nope, the problem persists after rebooting and clicking "Load Standard Profile from Git Hub".
Not sure if this is relevant, my hub and drivers have not been updated in a long time ~2 years.
Tried using your driver today and failed multiple times despite installing and reinstalling via HPM.
After that I also updated HPM and Hubitat Platform version. Still does not work after reinstalling the driver.
See the screenshot below.
Platform Version
2.4.4.155
Hardware Version
C-7
Sorry mate, I don't have many more ideas at the moment what could be wrong ... I have seen this type of exception "error converting JSON: expecting a ....." to happen immediately after the hub reboot - seems like the HE local file storage system needs time to initialize after the drivers are already loaded and running ... or something similar. So that's why there is a rather complex JSON load->parse retry mechanism that hits after a hub reboot.
I suppose you get the same error when you click on the "Load Standard Profiles From Local Storage" button?

Actually, there is a workaround - use the latest 'hardcoded' version of this driver :
Install this driver version 3.5.2 manually; it supports Sonoff SNZB-06P.
The driver name is 'Tuya Zigbee mmWave Sensor ver 3.5.2', so both the old and new drivers can coexist.

Yes, the same error happens when clicking on "load from local storage"
The workaround works perfect for me. I'll keep you updated if the new driver somehow works again.
Cheers!

Suspected bug - The file downloads successfully but then fails to parse. The driver is downloading 115,210 characters just fine, but the JSON parser chokes on a specific character in the file — that version string "v.4.1.3 - WENZHI_MTD285_ZB profile improvements" contains something that breaks the parser.

Hi @sigfreund ,
Thank you for the report!
Yes, there was a bug in the latest standard JSON file (a missing comma). Now it should be fixed - please click on the "Load Standard Profiles From Git Hub" button and let me know if your device is detected and working now.

Hi @kkossev,
I’ve not been able to see any profiles in preferences of the driver for a while. I tried to load it from github, local storage. I tried to repair the device, reintstal the driver, tried almost everything. Am I missing something somewhere?
These are the logs:
Running device _TZE200_holel4dk

Did you check out the first post of this thread? Krassimir posted an update there late last year about the future of this effort.

Hi @kejin ,
The logs are showing that the ‘device profiles’ are loaded successfully to your hub local storage…. What do you see if you go to the Preferences tab, ‘Device Profiles’?

I created this driver with ChatGPT. I have tested most of its functions, and it is working quite well for me. I am using it in a small room.
@Rxich the driver code and the JSON definitions were just updated :
Can you please try again and let me know if you still have problems?
BTW, I don't see what is your device Zigbee model/manufacturer from your post ..
