After upgrade from 3.3.0 to 3.3.1 temperature stuck at 85 degree C.
sonoff has to publish new FW avoid od this problem.
Hi, the problem is in sensor socket contacts. Open TH16 ant slightly push down 1st contact (photo above) and plug temp probe again.
Sorry for all the inconveniences caused to you.
Our technicians are finding a solution to fix this issue. It will take some time to doing some tests to locate the reason. Please wait patiently.
Hi, any update on this? Just bought TH10, updated on first power on to 3.3.0 (latest available), and sensor reading is only 85, restarting/replugging does not help. Opened the case and gently pressed the plug connectors, doesnt solve the issue.
Michael - did you ALSO perform the contact reset or just this board moving procedure?
This is a disaster of a release - it essentially BRICKS the device.
How can we go back to previous firmware?
I would also like to go back to the previous version.
the one that worked
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
I think we are discussing 2 (or more) different issues here. My issue wasn't with the firmware. I bought a new device - both with upgraded firmware and inital one - readings were only 85°. Then flashed Tasmota firmware (very easy nowadays) - only 85° readings too. By moving the mainboard as described and bending the contacts a bit the sensor started to give the proper readings. So no firmware issue here at all, but contact issue at least for my device.
I had the same problem on 2 thermostats. I have enlarged the hole of the jack connector for a better connection to the jack. The temperature has returned to normal on the latest firmware.
