Good Sensor, Working very well with tasmota. Better than the newer models PIR 3 in terms of battery, PIR 3 worked for a month these work for at least 6 months on heavy usage. Still pricey but robu is offering the lowest price in India as of now, I used to order these for INR 400 when AliExpress was working.
