If you installed node-red-contrib-bme280 in the config window just change bus# to 0 and it should work. I noticed that i have to reboot each time a new node is installed to see it or make it work.

What is the correct and easy way to route traffic to the cellular modem with the Omega2 LTE when there is no wifi?

Apn is set, 'o2lte data enable', got an ip address with 'ifconfig wwan0', i can ping from wwan0...

I disabled wifi on my router for the test and i can't connect to my mosquitto server with node -red or make opkg update or anything network related.

Thanks.
