Tutorial to flash Tuya Motion PIR - No Solder Method

Tasmota Firmware - Flashing USB Serial - No Solder Method with Tasmotizer

My device came with a blue led cover due the image is for red.

To get the PIR to send a proper on/off status, set the switch mode to 2

SwitchMode1 2

Buzzer is the alarm speaker

Switch1 is the PIR sensor

Relay1 is for the led light on/off

Not sure if the side button should be exposed somehow

Works powered over USB-C without the battries (they should be used as backup as instructed in the manual)
