I have been enjoying driving my APA102 RGB LED strip from Omega (first version), using just two wires (and GND, of course): MOSI on GPIO #18, and SCK on GPIO #6 .

Now I'd like to migrate my project to Omega2+. So, I connected the LED strips GND to Omega GND, data line to GPIO #8, anc clock line to GPIO #7 (following the pinout). First thing to notice was that Omega apparently sends some data at boot because ~30 first pixels of the LED strip are twinkling in various colors. Then, it turns out it has not booted properly, because when I attempted ssh login, I found myself in some broken shell (no banner). Rebooting with the SPI wires disconnected resulted in a corrupted boot so that finally I was forced to do factory reset.

I am surprised that such a supposedly simple thing resulted in such a challenge.

@Don-DeGregori Try some tutorials on YouTube, there are many. Node-RED is a tool for developing/prototyping internet-connected gadgets. At no time you can make a project that monitors twitter activity and blinks a LED when certain hashtag is detected. That's just a trivial example, of course. See the use cases from users in YouTube.

src/gz omega2_onion http://repo.onion.io/omega2/packages/onion

Yeah, I thought I'd try and add this to my distfeeds.conf, but (as one could expect), the packages file did not pass the opkg signature check. I am pretty sure there are no specific restrictions that would not let the Node-RED be run on Omega1 hardware, but Onion apparently is now all-focused on the Omega2 and could not be bothered porting the Node-RED to the Omega1 repo. That would be shame if they abandon Omega1 just because there's now #2 in town.

I wish admins like @Lazar-Demin or @Boken-Lin could just say if they plan to add Node-RED to the Omega1 repo or not. That's a big deal, if it can be made to run on Omega1.

@Joris-Mulliez said in Node-RED on Omega 1:

Oh sorry... I didn't notice you had a omega 1... Perhaps you can add some extra respositories ? (I have no idea of which one...)

Can you please list the URLs of repositories that you see when you do opkg update?

@Brian-Robbins said in Node-RED on Omega 1:

@Pavils-Jurjans
node-red-install-tool_0.1-1_mipsel_24kc.ipk
repo is at http://repo.onion.io/omega2/packages/

Ok, there's the catch. Omega2 packages. I guess that Omega1 does not support Node-RED then. :(

@Joris-Mulliez I get several pages of text when I grep red, mostly because the opkg list outputs the package descriptions. But I don't find the package node-red-install-tool what you mention.

Can I ask you to show from where you get your package lists? I am not sure how to retrieve list of repository urls, but I see them when I do opkg update (I've included those urls in OP). At least in those repos there is neither onion-node-red nor node-red-install-tool package.

@Theodore-Borromeo Of course, I did! The thing is there is no such package as onion-node-red (one can check in those package list links)! Perhaps there has been earlier and then was removed due to some incompatibility issues? I have no idea.

I was happy to discover that Omega supports Node-RED, when I stumbled upon this tutorial: https://wiki.onion.io/Tutorials/node-red

However, my joy soon faltered: when I do

# opkg update
# opkg install onion-node-red

all I get is

Unknown package 'onion-node-red'.

@Gauthier-Michoud @MultiDJRoni, did you succeed installing Node-Red? When I do

# opkg update
# opkg install onion-node-red

All I get is

Dammit, the problem was from totally different department!

The actual error was caused by the Simple HTTP Server trying to output its log where there was no place where to output, as the script was launched by system at startup.

I have silenced the console logging by implementing log_message method in my HTTP handler. Tada! Everything works now.

class MyHandler(BaseHTTPServer.BaseHTTPRequestHandler):
    def log_message(self, format, *args):
        return

A somewhat brutal way to silence logging, so I'll replace it by logging to file, though.
