{"NAME":"Y09","GPIO":[0,107,0,108,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":54}

This device now comes with a Wi-Fi module incompatible with Tasmota

Please read TuyaMCU article to understand the terminology and configuration process.

This is a Tuya/Smart Life battery powered contact (Water Leak) sensor. Runs on two AAA batteries (not supplied with the device).

Flashing

There’s an unofficial binary, compiled from current development release. Flash at your own risk.

Serial

To flash the device solder directly to TYWE3S TX, RX, GPIO0, VCC and GND pins (optionally solder GPIO0 to GND but you only need to connect it to GND during boot). You also need to disable the MCU by connecting RST to GND, otherwise you will be unable to flash.

Configuration

If you’re using battery power you need to prevent the device from going to sleep by actuating the reed switch constantly (approximately every 5 seconds) during the configuration or use the serial message.

You can use

SerialSend5 55AA000200010002

shortly after boot to put the device into wi-fi search mode (rapidly blinking red LED) which will keep it powered on for around 60 seconds.

Change device to a TuyaMCU module (or apply the provided template, result is the same)

Module 54

Disable multipress button options to prevent a device reset or Wi-Fi AP config mode, disable Power Cycle recovery, turn on TuyaReceived publish to MQTT and set switchmode to follow instead of toggle

Backlog SetOption1 1; SetOption65 1; SetOption66 1; SwitchMode 1

If you are using a new device and replacing the CB3S module to flash Tasmota, you may also need to set the MCU baud rate to 115200 for it to work:

SetOption97 1

Switch the device to battery powered sensor mode (fnId 51):

TuyaMCU 51,21

Check with TuyaMCU for the following configuration:

 {""TuyaMCU"":[{""fnId"":11,""dpId"":1},{""fnId"":51,""dpId"":21}]}
