Long time weewx user, had been running on a RPi3b with an AcuRite 5-in-1.
Currently, I'm trying to upgrade to an AcuRite Atlas w/ lightning sensor &
SDR & BME280 running weewx 4.5.1, also on a RPi3b.
weewx is running fine with Belchertown skin, SDR is working fine (except
trouble getting lightning to show up in reports). But for the life of me, I
can't get BME280 working with weewx. I have a Grove BME280 module.
I can see the module in i2c: port 1 0x76. I can run a bme280 test which
outputs:
Chip ID : 96
Version : 0
Temperature : 22.77 C
Pressure : 1014.92710409 hPa
Humidity : 49.1006560524 %
but dmesg is giving me:
pi@raspberrypi:/home $ dmesg | grep i2c

I'm ending up with additional [bme280wx] entries under weewx [engine]. So
when I try to run with these settings, weewx stops:
pi@raspberrypi:~ $ sudo weewxd
Traceback (most recent call last):
File "/usr/share/weewx/weewxd", line 264, in <module>

mod = __import__(module)
File "/usr/share/weewx/user/bme280wx.py", line 6, in <module>
import bme280
ModuleNotFoundError: No module named 'bme280'
If I comment out the bme280wx items, weewx runs fine. I've also tried some
of the adafruit bme280 modules / methods, but that also fails.
I'm wondering: does my BME280 module need something specific to being a
Grove branded module?
I'm still pretty green at all this Atlas SDR / BME280 (the old 5-in-1 was
more straightforward), and would greatly appreciate any pointers.
Cheers!
