Setti+ weather station SMS603 - no temperature readings in history

Hello.
I am observing a problem in the operation of the Setti SMS603 weather station.
Well, some temperature measurements from the sensors are not available in the
history presented by the application on the smartphone. At the same time, humidity measurements from these sensors are available at the same moments and
temperature measurements from other sensors.
I am therefore ruling out a problem with the Wi-Fi network operating in 2.4 GHz mode.

Thank you for the detailed description - it helps a lot with the diagnosis. The problem with no temperature measurements in the Setti+ SMS603 app history, although other data from the same sensors is available, does indeed look like something more complex than just a Wi-Fi issue.
🔍 Here's what I've been able to determine from available sources and similar reports:
🧩 Possible causes of the problem
- Data synchronisation error in the Setti+ or Tuya Smart app
Users have reported that the app sometimes fails to save full sensor data, even though it is temporarily visible on the home screen.
- Problems with the format of the sensor data
It may be that the sensor is transmitting data in a format that the application incorrectly interprets as incomplete or incorrect - e.g. a missing unit or an out-of-range value.
- Transmission time too short or radio interference (433 MHz)
The Setti+ SMS603 sensors communicate with the main unit via the 433 MHz radio band. Interference (e.g. other devices, thick walls) can cause only part of the data (e.g. humidity) to be received.
- Station or sensor firmware error
If you have the possibility to update the station or app firmware, it is worth checking. Some versions have had problems saving historical data.
✅ What you can try
1. Reset the sensor that is not recording the temperature
Remove the batteries for a few minutes and then re-pair it with the station.
2. Change its location
Move the sensor closer to the main unit or to a location with less interference.
3. Check the application and firmware version
Make sure you have the latest version of the Setti+ or Tuya Smart app. If the station offers a firmware update, it's worth doing.
4. Record observations and report to the manufacturer
If the problem persists, it is worth reporting it via the contact form on the Setti website or via the app.
Would you like me to help you formulate a report to the manufacturer or check if a firmware update is available for your model?

>>21727771 Thank you for the hints. I tried a full reset of the station and sensors. I'll see in a while if that helped.
