Thonny won't import the BME280 module and gives SSL: CERTIFICATE_VERIFY_FAILED error

[Badflash2]

I suspect the Windows Update this morning is the cause as things were fine yesterday, now Thonny is acting odd. I'm using a Pi Pico W with the latest RPI_PICO_W-20240105-v1.22.1.uf2 file. I was trying to use a BME280, got the driver file and added it to the Pico. When I tried to import the driver it said it could not find it.

I went to Thonny Tools and attempted to use PyPI to import the file and got this error:
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1007)>

Try opening the package directly:
bme280

Opening directly just gave me more grief.

Install from local file also refused to work.

Any help would be appreciated.

PyPi modules seldom are Micropython compatible nor are they AFAIK installable to a microcontroller. See https://github.com/mcauser/awesome-micropython for a list of BME280 drivers (and for many other Micropython packages). These drivers are usually just one .py file. Copy that with Thonny or mpremote to the /lib folder of the microcontroller and you are good to go.

It was windows. Someone suggested I use a file called lets-encrypt-r3. It created a cert that let it work.
