Are there faked BME280 for sale?

Hi,

I bought BME280 sensors on Amazon.
Surprisingly cheap for the global shortage, 10 pcs for 9,09€. Sold directly from Amazon, Brand “Mxzzand”.

On first connect the the airrohr they are recognized as BME280, with temp, hum and pressure shown correct. But after reboot they show up as BMP280 with only temp and pressure.

Am I doing something wrong or are they fake?

Thx

Hi,
It means it is actually a BMP280 not a BME280. Did the sensor measured THP at least once ?

As I wrote, on first connect they measure temp, hum and pressure just fine.
After reboot they are recognized as BMP280.

I returned them to Amazon without problems.
