This is a Tuya siren with temperature and humidity sensor. Runs on USB and two CR123A batteries as backup (not supplied with the device).

Identified with MCU Product ID: {"p":"ymf4oruxqx0xlogp","v":"1.0.1","m":0}.

Flashing

If you have issues flashing with tuya-convert you can flash the device using serial. There are labelled pads for all needed GPIO’s on the board. You have to remove the resistor next to the TX pad to isolate the ESP8266 from the MCU.
