UZ-1T and ZTH11-3.0

[notgood]

Another device: UZ-1T.

Quite easy to disassemble, PCB slides out of the case, no desoldering required.

Pinout seems to be identical to ZY-ZTH02:

SDA  31  PD2
SCL  23  PC3
SWS   5  PA7
TXD   6  PB1
RXD  17  PB7
LED  22  PC2
KEY  14  PB4

Identifies as Tuya TS0201.
I've tried to flash 1002-d3a3-66993001-ZYZTH02z_v0137.zigbee in Z2M custom OTA, but device doesn't seem to accept it.

Don't have required programmer on hand to dump original firmware. My CH340G TTL adapter got LED's on TX/RX lines, it probably won't work with TLSR825xComFlasher.

Cut out LED's on my TTL adapter, dumped firmware three times using TLSR825xComFlasher, all three dumps had identical md5sum.

https://pvvx.github.io/ATC_MiThermometer/ZigbeeTlcIdxOTA.html tool doesn't recognize it though:

File: stock_UZ-1T.bin
Extracting an OTA binary file from address 0x000000...
FW size: 0x008F98 (36760) bytes
Invalid size pointer in Telink OTA binary firmware!

Anyway, flashed ZYZTH02_v0137.bin: sensor, LED, and button seem to work just fine.

Added recognition of the new boot-loader variant. -> ZigbeeTlcIdxOTA v0.7

TS0201 _TZ3000_dnpd6ayp
There is no information about version numbers in the bootloader and OTA.

There is no information about version numbers in the bootloader and OTA.

It mean no OTA possible from stock firmware, right?

Anyway, according to package, there also are UZ-2T and UZ-103T variants of this board, posting here in case somebody searches by model number.

Yet another board: ZTH11-3.0.
Semi-waterproof case, but otherwise pretty much identical to UZ-1T and ZY-ZTH02, so adding it to this issue.

Stock firmware is identical to UZ-1T

stock_ZTH11-3.0.zip

Flashed ZYZTH02_v0137.bin over serial, working as expected.
