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.

@Maxdog1982 check this docs article out: http://docs.onion.io/omega2-docs/node-red-article.html#installing-node-packages-that-require-compilation

Thank you very much, your solution solved my problem

Hi, could you help me to install the serial port on node-red? I'm trying to install it using Node-Red 1.29 from the palette and I have an error.

Awesome thank you these will be very helpful for anyone using node red with the expansions

I answer myself: possible solution: iptables -t nat -A PREROUTING --dst YOUR_LOCAL_IP -p tcp --dport 1880 -j DNAT --to-destination 192.168.3.1

@Bas-Rijniersce thanks .. work with me

@Don-DeGregori , wikipedia: Node-RED is a software tool developed by IBM for wiring together hardware devices, APIs and online services as part of the Internet of Things.[2] Node-RED provides a browser-based flow editor, which can be used to create JavaScript functions. Elements of applications can be saved or shared for re-use. The runtime is built on Node.js. The flows created in Node-RED are stored using JSON.

@Landon-Lin Just for reference, Omega1 and Omega2 can't do Node-Red without booting from external storage. Omega2+ has an onboard microSD card. You can configure it to boot from the SD card as in here https://docs.onion.io/omega2-docs/boot-from-external-storage.html (though the instructions don't match up well with current products). But the App Manager will still say Node-Red is incompatible with Omega2+. End-run around that using: opkg install oos-app-nodered No more storage issues but SD card is inherently unreliable so eMMC recommended for production as in the Omega2+ Pro. At least it does start up, haven't actually run any flows yet.
