Hello @crispyoz thank you for answer. thats solve my problem but temporary.

But ı found solution permanent. If bme280 connect correct in omega device and if you install packages i2c packages.

in the node-red flow just click your bme280 and change bus 1 to 0. That will change to i2c-0 permanent.

how to know bme280 connect correct in omega device ?

in terminal write i2cdetect -y 0 if you see 76/77 that's means you connect correct.

Hello, good day.

I'm trying to get sensor(bme280) in node-red. I installed bme280 node and ı got i2c-1 error.

"Sensor Init failed ->Error: ENOENT: no such file or directory, open '/dev/i2c-1'"

I search onion docs and found that i2c-0 comes default in device. How do ı set this i2c-1 ? or how do ı show my flow i2c-0
