just ran your bash... whoami is weewx
I don't normally run it as sudo... i did that as a test to see if i
could figure out what was happenning.
I am happy that I can run it as me... using weewxd... however when the
system boots it runs the service (I believe as root) and that is an issue
I do know that if I commit out the data_service line (in weewx.conf) for
the BMP280 all works no matter how I start it. (but then I am not
getting the pressure data).
I have run the three suggestions and have not had any luck.
I am going to try to install the BMP drivers in /etc/weewx and see if that
helps... although that process was a bit of a issue!!!
THanks
Ill let you know how that goes
