Itead, please removed "SOLVED" status from the post submitted previously by Gerhardt. We need the firmware release fixed

At my TH10 I get the correct values of temperature and humidity at start but never update. If I reboot get correct values again but never change.

Itead, when are we going to see a firmware fix for the TH10 /TH16? This is a known issue and your customers need a fix for your buggy firmware release !!!

This is a disaster of a release - it essentially BRICKS the device.


How can we go back to previous firmware?

Dear friends! All that you write correctly, the testimony is restored, but not for long. When the router is overloaded, 85 degrees returns again. The most important question is why this was not the case with the old firmware. In my opinion-firmware error in the initialization of the temperature sensor. Perhaps, on the available samples in ITEAD everything works - then it's in the hardware of our devices, but judging by the fact that this is typical for TH-10 - it's in the firmware. Contacts have nothing to do with it. Just when you remove-insert the connector sensor is initialized, and then for unknown reasons is a failure.With respect

I would like to downgrade to 3.2.2 version, but I have the 3.3.1 and I don't know how to revert.

Same problem as Rogerio except on the TH16. Humidity/Temperature is only accurate when device is turned on or the sensor is reconnected and stays at the same value/never updates.

i have same problem, it is working older firmware truely. But after fw update the temperature is 85 Celcius. This is not related with hardware problem, it is only FW problem.

I bought a new TH10. Doing a firmware update to version 3.3.0 right at the beginning. Now I noticed that the humidity display in the app is always the same. Only after I disconnect the device from the power or I plug the sensor out and in again the value is updated.

Enlarging the access hole has ALWAYS been necessary since the very beginning of the TH10 and 16. The thickness of the case together with the recess of the of the female receptacle has been a problem since day one. My TH10 and TH16 devices have worked flawlessly until the last firmware release that now puts the measured temperature at 85°C

I have the same issue. I did kill the power supply to the unit. it still gives the same reading. how can we rollback the firmware?
