No new measurements

[scattym]

I have just installed and setup omramin and gone through the init process, logging both into garmin and omron without any trouble.

In the app on my phone I can see measurements and I have hit the "sync" button to sync with the device by bluetooth.

When I run the omramin sync or omramin sync --days 6, it just comes up with "No measurements".

Device: Omron 7361T

Is this log from --days 6? It says from 2026-02-07 to 2026-02-07, and the timestamps show:

searchDateFrom: 1770382800000 -> UTC 2026-02-06 13:00:00 | Local time 2026-02-06 20:00:00
searchDateTo: 1770469199000 -> UTC 2026-02-07 12:59:59 | Local time 2026-02-07 19:59:59

This looks correct to me. There isn’t much I can do if omron does not return any measurements for the requested date range.

I found this, but it’s from years ago:
https://apps.apple.com/au/app/omron-connect/id1003177043

Maybe try an even bigger range? Like 30 or 100 days?

[scattym]

Yeah, I tried setting days to 365 and still nothing.

I suspect the data is in a different api endpoint or appid.

How did you find the current api endpoints and the current appids? Just wondering if there are other endpoints I could poke around to see.

[bugficks]

A capture would certainly help to compare the original request parameters with the ones used by omramin.

To get all endpoints, regions, etc you need to decompile the android apk or decrypt ios ipa :)

Capturing traffic used to be pretty simple by using a proxy like https://proxyman.com or https://www.charlesproxy.com. But recent omron connect versions seem to have introduced SSL pinning, though I don’t remember if that was EU version only. To bypass this you can use https://github.com/mitmproxy/android-unpinner with an Android emulator using this image

sdkmanager --list_installed | grep "system-images;android-33;google_apis;arm64-v8a"
  system-images;android-33;google_apis;arm64-v8a | 17      | Google APIs ARM 64 v8a System Image | system-images/android-33/google_apis/arm64-v8a

One major problem with the Android emulator: it does not natively support Bluetooth for connecting to physical Bluetooth devices. You can only use it for fetching data from the cloud.

I did set up an AU account today to verify the endpoint; looks good to me:
