Okay, so I’m not alone. 
Have you tried getting the temperature reading this way? I didn’t see any changes in the app when I tested it offline. 
Yes, I tested it — and no, you won’t see any temperature updates in the app when the device is offline.
Proximity Mode doesn’t broadcast live measurements over BLE the way Xiaomi sensors do. I believe that it only allows the eWeLink app to connect directly to the device when the phone is nearby, but the device still needs cloud access to sync data and show updates in the app. It is my intelligent guess since Sonoff never documented the BLE advertising format, and Proximity Mode isn’t a true offline‑broadcast mode — it’s just a local connection path for the app, not a standalone BLE thermometer, I think.

That would make sense, you’re on the right track.
Now I’m just wondering what the benefit of such a feature is… It won’t work when there’s no internet, so it’s not offline mode. So it’s supposed to be a reading when the device running the app doesn’t have internet, hmm?
But they should fix the bridge’s LAN mode operation, so it should probably also read the temperature then… unless the sensor goes completely blank without internet, leaving only the LCD display, hmm.
In what situations do you think such a feature makes sense?
Good question! If Sonoff added this feature, someone there must have thought it would be useful. At least it sounds good in marketing. It’s a bit like a microwave with a touchscreen and a gazillion fancy functions you’ll never use — and even if you read the manual, you’ll forget they exist after a couple of days.
I’ve got a different problem. My visiting elderly mother‑in‑law managed to completely break my heating automation. I need to rebuild it, because I never anticipated someone repeatedly opening and closing a window with that level of enthusiasm. The whole logic lost its mind and went straight into the bushes

I know this pain… More than once in my life I have done things correctly until I am confronted with reality and suddenly it turns out that my mind was incapable of predicting certain human behaviors.
Changing the subject back to the original thread… I tested LAN mode again, and it’s still the same as before: it doesn’t work.
I disconnected the WAN cable, completely eliminating the internet connection. Only the LAN connection remains. It’s the same as before, meaning I can control devices like the S60TPF, S26R2, and Micro-CFH and turn them on/off without any problems, but I can’t do anything with ZigBee, even the S60ZBTPF.
The ZBBridge-P simply lost LAN mode completely. And it’s not even about local scenes, but a complete lack of interoperability, which is strange because even the old RF HUB has LAN mode, and we know from the past that the ZBBridge-P also implemented it.
Either they broke something in some firmware update, or it’s a problem with the eWeLink app on Android. And it’s definitely not a device limitation, because it’s cheap, as one colleague tried to mention. They messed something up, and as usual, no one noticed the problem…
How do we know that
Perhaps Pro stands for Probably not working the way you expect?

Still no reaction…
So it turns out the device doesn’t have LAN mode at all… So either they removed this feature somewhere along the way in the firmware or it was a lie from the start!!!

Hi,
Thank you for reaching out!
Unfortunately, the ZBBridge-P hub currently doesn’t support LAN control functionality. However, you can set up local smart scenes to operate the Zigbee devices locally.
Kind Regards,
