Original one, it is probably the kickstarter one too!
I've got three running in my house. All run php either via http or on a loop/cron/schedule and interact with relay modules or 1wire temperature sensors.
One monitors external temperature and sends the data to weather underground.
One monitors office temperature and fetches data from my solar panels, then turns on the heating via a relay if I have excess solar energy. It also controls some outside garden lights on a schedule via a relay.
One monitors two areas of the house AC to DC battery and inverter cabinet.

All of the above also get ingested into a database for graphing.

I also had a friend who wanted to remotely control their gate.. so they've got one using php and relay outputs.

And finally.. for several years a school had a dodgy boiler which would trip out and only get noticed hours later (or if a weekend, didn't get noticed until too late on a Monday morning!).. an onion was eventually setup there using GPIO to detect the boilers failure relay output and send an email to the janitor/caretaker to warn them the moment it had failed.

All would have been possible with a Pi or similar, but the form factor of the Onion and features + packages available made them ideal.

And after 6 more years of use!

And also a huge thank you to those at Onion; your boards have been powering some home built automation flawlessly (other than screen burn in) for 6 and a half years. It's stunning how helpful a device with WiFi, GPIO and shell/php can be.

If anyone is interested in an update.. here it is a year and a bit later:

Brand new Omega2, never used until today.. setup today and firmware updated:

What am I doing wrong :s

I've also downloaded all the package list files from "opkg update" and manually searched them.. procps doesn't exist.

I did source it from another place though but I'm unsure if this is a bad idea:

wget https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/packages/procps-ng_3.3.11-3_mipsel_24kc.ipk
wget https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/packages/procps-ng-watch_3.3.11-3_mipsel_24kc.ipk
opkg install procps-ng_3.3.11-3_mipsel_24kc.ipk
opkg install procps-ng-watch_3.3.11-3_mipsel_24kc.ipk

Why does it seem my Omega2s can't find the package yet you can? Are you on an Omega2 or an original?

Nothing to be fixed but thought I would show people my observations with the OLED screen.
After around 6 months I've got slight burn in!

Fun

Unless I'm misunderstanding what you want to do - I think the command you want is expled?

root@Omega-1097:~# expled --help
Functionality:
        Set colors on Omega Expansion Dock LED

Usage:
/usr/bin/expled <hex value>
        Displays color of hex value on the Exp Dock LED

/usr/bin/expled -help
        Displays this prompt

I see the same..

Very confused. I've got a second Onion2 here which I will try as soon as I get a chance.

@Brad-Buskey said in procps missing?:

it will look for any instance of procps. it returns:
procps-ng - 3.3.11-3

I feel like I'm missing something.

I'm almost certain I've used opkg to install procps (most importantly the watch command) on my Omega Onion.. I've gone to setup a similar system on my Omega2 but can't find anything matching procps:

root@Omega-B79F:~# opkg update
root@Omega-B79F:~# opkg search procps
root@Omega-B79F:~# watch
-ash: watch: not found

Any ideas?

It is connected to a commercial gas boiler system. The terminals it connects to claim to just be a certainly doesn't output anything like AC or high DC when triggered. All the wiring does run directly alongside the main AC electricity feed into the boiler though.

I will see if I can borrow an analogue test meter and see if I can see it wobbling around.

Hi all,

I've got a strange problem with GPIO on an Omega2.

When I test my input through a digital test meter I see, at most, 0.3v coming from the equipment I am connected to. However the documentation for the Omega2 seems to say that you should only see a high input when it it goes above 2.0volts.

Example:
https://gfycat.com/BrokenRectangularDorado

Any idea what is or could be going on?
When the connected equipment goes high (outputs 3.3volts) I see a constant HIGH on the Omega2 GPIO but it is slightly annoying seeing the LOW as as "flapping" between high and low.

I can only assume interference from mains wiring that runs alongside the twisted pair that I'm using to connect my equipment to the Omega2.

Any suggestions would be lovely.

Sounds like you don't have the .php interpreter setup in the http server config?
Make sure that the following section of the instructions got completed:

"Next we need to edit the uhttpd file, you can do this by using this command:"
(The list interpreter and index_page addition to the config etc.).

Good spot.. only because it is attached the same tool that has a thermometer on it too. The thermometer was my main way to tell the temperature in the office before I got the Omega setup.

Compass is, clearly, useless when vertical (and next to power conduit).

I just bought something random and hoped it would do the job.. it does

Solid state relay to control the 1kW load ( http://amzn.to/2grrQSh )

I'm then using the easy to access jumpers on the temperature sensor to feed 3volts into the solid state relay via the relay expansion which is behind the oled display.

I am doing very much the same!
Here is my current working (but not very tidy) setup!

Soldered the wires onto the GPIO pins on top of the OLED display. Then off to a solid state relay to control the 1kW load ( http://amzn.to/2grrQSh )

I'm then using the easy to access jumpers on the temperature sensor to feed 3volts into the solid state relay via the relay expansion which is behind the oled display.

In the default mode, as far as I noticed, the Onion does NAT from the AP to the normal wifi.
This means that clients connected to the Onion get a 192.168.3.something address (as far as I remember) and not, for example, a 192.168.1.whatever address for your normal "main" wifi.

In this mode if the main wifi goes down your clients connected to the onion will still be given IP addresses and will still be able to communicate between eachother. They will just lose access to the internet and likely to DNS.

It is always possible to reconfigure this AP mode though so it works differently. But as far as I remember and noticed the default mode works as above.

I'm unsure on the maximum number of clients information.

Hi All,

Does anyone have a good solution to switch either a 1 or 2kW resistive (or inductive if possible) load?

Any method is fine, either a wifi IoT type device that can be controlled or sent a command direct from the onion (without ifttt or some other cloud service in the way) or a contactor that I can connect to the Onion relays. My preference would be to keep high voltage away from the Onion relays (even if low current just controlling a contactor).

Hope someone has some advice. There seem to be a lot of devices out there but I've no idea on what is actually a good solution.

There is some sort of overlay / merging going on..
While the article is about extending storage the top part of the article may be helpful in the explanation of how the overlayfs works.

@Matthias-Nowak Here is my rather dusty and cat hair covered dock photo! Sorry it is so grotty.
I've tried to annotate all the ones I could read.

@Kit-Bishop @fossette I've re-tested without anything connected. So just the power dock and no Onion, 1-wire sensor or OLED display.. same power "leak".

Seems to hang at around 4.2mA but then if you disconnect and reconnect within about 500ms or 1 second it can jump and stay as high as 9.2mA!

https://vimeo.com/184930331

Sorry the video doesn't show me connecting and disconnecting - I only have two hands which were required to hold the meter probes while the camera was balanced on top of a cup looking at the display!

Disappointing as it means my project (as someone calculated) seems to run the battery down even while off in about a week. Not too much trouble to splice in a physical switch between the battery and the dock but I feel like this shouldn't be a problem in the first place.
