Hello,

It seems I can’t update the sensor with the button on the Telink Flasher webpage. If I click on "Custom firmware : TS0201_v47.bin", nothing happens.

Any idea ?

Thanks

What firmware version to flash to go back to BLE from Zigbee?

Is this device supported ?

I want to use with BLE protocol. Should I buy zigbee or Wi-Fi ? as I will have to push firmware using serial I think it doesn't matter.

Hi,
can you build a firmware for a modified ZTH01?
I have removed the so16 and would wire the pins accordingly to the attached picture.

SCL (AHT30) - C3
SDA (AHT30) - C2
VDD (AHT30) - D2
Button - B4
LED - B5

Best regards, Stefan

I have a TS0201 by _TZ3000_xr3htd96, which is already Zigbee and reports the following OTA data:

Manufacturer ID: 4417 (0x1141)
Image Type: 54179 (0xD3A3)
Image Version: 70 (0x46)

Is there any method to use Zigbee OTA to convert this to an optimal pvvx zigbee firmware (1141-0211-01183001-ZTS0201Z3000.zigbee)?

Or is the only way to flash these from factory, with a wired USB-TTL programmer?

Interesting project! So it seems to be possible to turn these ZTU zigbee modules in BLE with your custom firmware.
Will order a TS0201 to test.
I have a Tuya ZTH05 temp/humidity ordered that will be delivered soon.
I read about this ZTH05 the battery drains too fast but it seems that it is equipped with the same ZTU module.
So perhaps this ZTH05 could be added to this repo?

TS0201 shows up in Home Assistant:
binary_sensor.ts0201_opening

Is this implemented in the firmware?
If yes, wich I/O pin to use to connect a reed switch for example?

I was wondering if this issue can stay, or if others are interrested, but can other please share aliexpress links for the TS0201 as showin with the header for flashing etc.? It seems to me that all the tuya zigbee ones use same case, but different internals. Or is there some secrett way to search and spot these (telink + header)?

I did created flashing jit for WSD500A, but header is always nicer.
In general these AAA battery based devices seems to last much longer, especially in cold, than cr2032 ones. I would like to monitor temperatures and humidity in remote property, that is quite large,
BT - epshome gateways - wifi - vpn, is the best way, at least for me, to collect the data. And with BT i just do not need to care about pairing etc. So these firmwares are great.
So that is why I'm looking for rather easy way to modify about 20 of these. But last time I ordered from few selers all were wsd500a and with those, i have success in 1 in 10 attempts, if that, when flashing.

I have this USB to serial adapter. Which pins do I need to connect to the Telink SoC ?

Hi,
It seems very promisig, but not clear what flasher cable is needed, how to connect it etc.
Could you share more detailed flashing instructions?
Thanks in advance!

Hi, I bought a similar round sensor: TH03Z
The sensor uses a ZTU module and a 2450 battery.

I think the sensor is being used: GXHT30
The GXHT30 sensor is fully compatible with the SHT30 sensor.

I tried to flash the firmware from the TS0201 sensor, but instead of readings, as expected, I received zero values :)
(I don’t think it was worth removing the protective film from the sensor, but I did it while trying to find the markings)
