Firmware for ZTH01 and ZTH02

[baetzst]

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

The firmwares is the same for:
TS0201 (_TZ3000_xr3htd96, _TZ3000_qsefbina): Tuya ZigBee
TH03Z (TS0201 _TZ3000_dowj6gyi): Tuya ZigBee
The differences are only in the number (name).

GPIO	Function
PC3	I2C SCL
PC2	I2C SDA
PC0	KEY (to GND)
PB4	LED (to GND)

Sensor: SHT30 or CHT8305.

The sensor AHT20..AHT30 in TS0601 (TZE200..): Tuya ZigBee ZTH01 and TS0601 (_TZE200_9yapgbuv): Tuya ZigBee ZTH02 is not yet supported.

When drawings with jumpers for both options are ready, then perhaps firmware with support for AHT20..30 will appear...

I measured my ZTH02. Pinout is the same as for ZTH01.
I made some drawings for both versions with jumper wires.

ZTH02

BLE:

ZTH01

GPIO_PB4 - KEY
GPIO_PB5 - LED
GPIO_PC2 - SDA
GPIO_PC3 - SCL

Support sensors: SHT30, CHT8305, AHT20, AHT25, AHT30.

The test firmware is ready.

Nice my zigbee ZTH02 works now perfectly !
Is there a way to setup offsets for temperature and humidity (via a zigbee send command for example)?
