  Sorry, I think addressing the root cause would be my suggestion, not by throwing a bigger battery.

  @Lazar-Demin Yes the GPIO 0 was plugged into the SSR 3-32V+ and the ground was plugged into the SSR -

  There was nothing connected to the SSR load side during my test.

  I know the last reply to this topic is from nearly a year ago, but just wanted to report that I just installed OctoPrint v1.3.9 on my Omega2+ with the latest 0.2.1 (b199) firmware (had 0.2 or the last of the 0.1 line and OctoPrint 1.0.0 when I used it last), and it seems to be working fine with my Kodama Trinus printer just fine... Thanks to all the posters who suggested the swap memory, python-dev/gcc and octoprint serve --iknowwhatimdoing workarounds / updates to the instructions... after some fumbling around I was able get it all working! ;)

  @Tisham-Dhar Ah I misunderstood what you meant by "compile a custom spidev outside of the feeds/onion/python-spidev"
  Yes, what you're doing is a good idea.
  I would also suggest looking into the USE_SOURCE_DIR flag, it allows you to use/compile a local copy of the package source code. More info here.

  @Maximilian-Gerhardt I was thinking to remove the jack and solder to the points. I didn't know about Ethernet ports having integrated transformers though. I found a close-up of the board and I see a transformer after, but it would be hard to know for sure without taking one apart.

  Assuming the transformer is on the board and not the port, would that work?

  Adafruit has a library at https://github.com/adafruit/Adafruit_FT6206_Library and I've done some things with I2C on the Omega2 at https://github.com/gamer-cndg/omega2-wii-classic-controller using https://docs.onion.io/omega2-docs/i2c-c-library.html. Combine those and you should be able to port the library.

  Double-check that you have RX and TX connected correctly - they're easy to get swapped, as the usual convention is to connect TX of one device to RX of another.

  Also, you can check that you're getting bits by cating /dev/ttyS1, or using a terminal program like minicom or screen.

  I haven't found the precise answer to my problem but I am happy I have the resources to sort it out myself now.

  The resource I have found especially helpful has been a tutorial by Steve here:
  "Using The Mosquitto_pub and Mosquitto_sub MQTT Client Tools- Examples"
  http://www.steves-internet-guide.com/mosquitto_pub-sub-clients/

  It has also been useful to practice simple queries against a MQTT test service here:
  https://iot.eclipse.org/getting-started/

  Hope that helps someone else

  Awesome tutorial and really cool idea! I am running into an issue though and thought maybe you would know how to help me out since you just did this. When I go to initialize my postgres db, it gives me this error:

  fixing permissions on existing directory /root/pgdata ... initdb: could not change permissions of directory
  "/root/pgdata": Operation not permitted
  pg_ctl: database system initialization failed

  I followed your instructions and did the chmod 777 /root/pgdata before initializing and it doesn't seem to be working. Does this make sense to you?

  I use 2 methods:

  ping my webserver run ifconfig to check for existence of apclio and local IP address

  from result of both I could tell if I needed to call wifimanager to restart. Since b17* it's been stable enough to reconnect itself so I no longer use this and I cache data until I am able to connect again using urllib2.
