Tutorial to flash Tuya Motion PIR - No Solder Method
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
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)
