Aqara TVOC sensor OTA completes but datecode not updating

[ptr727]

What happened?

On 14 May 2022 I deployed an Aquara TVOC VOCKQJK11LM and updated the firmware using built in OTA to "dateCode": "20220222".

Yesterday (17 July 2022) I deployed a second VOCKQJK11LM, again did an OTA update, but this device still reports "dateCode": "20210204".

OTA reports no update available.

I removed and repaired the device, same.

I downloaded the OTA file and placed in local OTA index file, still reports no update.

}

I followed troubleshooting steps from here with no solution.

What did you expect to happen?

I expected both devices to update to "dateCode": "20220222", and both devices to behave the same.

How to reproduce it (minimal and precise)

• Acquire VOCKQJK11LM.
• Enable pairing in Z2M.
• Pull battery isolation tabs from device.
• Pair success.
• Verify firmware date code.
• Click device button to wake it.
• Start OTA process.
• Complete OTA.
• Confirm firmware date code updated.

I experimented and updated another new sensor using the M2 hub and the Aquara app. As expected the datecode and application version updated.

"applicationVersion": 29,
"dateCode": "20220222",

Some more info.

• Datecode will only update after removing device from network, and then re-adding.
• The application version never updates, stays on 24, vs. M2 hub updated devices show app version 29, matching firmware.
