Just testing myself how to hide a text (or a picture) - the easy way is now gone .. 
What worked in the default mode with the preview is copying and pasting this text :
[details="click to expand"]
hidden text is here
[/details]
Testing again 
hidden text is here second try
Make sure when copying and pasting the details snippet you are in a 'normal' edit mode,,with the preview pane on the right side :
wow, too much complicated for me ...
Now checked the logs again. Only temperatures and humidity seems update. All the other values are from the initial Configure.
Cheers
Petteri
Did you pair the device again with the newly assigned driver?
For many Tuya devices, it is necessary to pair them with the correct driver.
The frequently repeated rule to press the 'Configure' button after switching the drivers does not apply to the Tuya devices.
Yes. Removed device and the old driver. Did just again and only temps and humidity updates.
Cheers
Petteri
What happens if you click on the Refresh() button ?
Nothing
All those values show unchanged in debug log. Those values must change like. Tds = 0?
Cheers
Petteri
Sorry for the long log. Cannot get spoiler or details to work.

Same problem is reported in SmartThings forum :
Maybe a faulty sensor? 
The decoding in the driver is definitely correct, it is the device sending zero values …
Is the probe fully immersed in ordinary tap water?
There are three different models of the same device, which one did you pay for?
Hi
Maybe faulty one then... The one I have is ZG-109TDS that is supposed to be 7in1. Atleast that is printed on the sensor's battery cover.
Keep it - we may be missing something at the moment. I’ve also asked for more details on GitHub. This is a very new device, and there aren’t many reports yet about how it performs.
Finally working water values. Gemini fixed the code. Key was to parse hex values

Requesting factory firmware (.bin) for Excellux ZG-109TDS / ZSSF-NTDS-10 (Telink TLSR8251) to fix EC/TDS sleep bug
Hello community!
I have the Excellux ZG-109TDS 7-in-1 water quality monitor (PCB marked as ZSSF-NTDS-10, powered by Telink TLSR8251 chip).
I am facing a common issue: the sensor only updates air temperature, humidity, and probe temperature. All other values (EC, TDS, Salinity, SG) are permanently stuck at 0 or do not report at all.
Interestingly, I hooked up an oscilloscope to the EC probe lines. When I touch the circuit with the probe, the capacitive noise triggers a hardware interrupt on the ADC, forcing the TLSR8251 to wake up and temporarily generate a proper square wave (meander), sending valid data to Zigbee2MQTT for a short period. Once the oscilloscope probe is removed, the MCU falls into an aggressive deep sleep loop again, disabling the PWM/ADC generator for EC measurements.
The seller confirmed it is a factory firmware bug related to the power management configuration of the TLSR8251 MCU, but they haven't provided the updated binary yet.
Does anyone have the factory or corrected .bin firmware file for this device? I have a USB-UART flasher ready to flash it via the SWS interface. Thank you!
