Ok, thanks! Seems as if you are correct! I am now using the following 3 gpio's: 2, 3, 18. Seems to be the combination that works for me. Would be nice if we could get some sort of definitive doc that might let us know whats up. Would also be nice if the docs were consistent.
This (https://docs.onion.io/omega2-docs/expansion-dock.html) shows one thing, but the GPIO app on the onion console does not even have 11 there at all! Why?
Thanks for the info!
Hello guys,
I have 3 gpio pins and 3 relay modules connected to the omega 2+.
However when these are connected the 2+ does not boot. Is there some trick? Some GPIO pin's I should not be using?
I am using pins 6, 8, 9 (according to new docs for Omega 2+). Still using omega 1 dock, is this a problem? I thought they were the same. Pins 8, 6, high on boot most times.
I should also note that the exact same setup (different gpio pins) worked for a long time with an omega 1. If I use the omega 1 it boots (gpios don't work but that is to be expected) without issue.
Help is appreciated. Thanks!
It should also be noted that mixing both is great as well. For example:
opkg find python-* | grep ssl
Will find all python packages that contain the characters "ssl"
To find things you can also do this:
opkg find python-*
...
Hello guys.
I have written a small script to integrate gpios and relays into home assistant as restful sensors and restful switches while trying to keep the number of packages required to install to a minimum.
I am thinking of a way to integrate the OLED into home assistant, but don't really know what I might use it for with HA. Any suggestions would be welcome.
If anyone is interested in this script please let me know. I would be happy to post it.
It isn't. Its just a convenience. You can definitely compile on your machine. Its just easier on the cloud.
I personally use python. Fast enough for my needs, and much easier to deal with.
Thanks,
My system is completely autonomous. I use python sockets to do this. However, I would like to add my openwrt router to the onion cloud and not relay messages to it. Think this is possible?
Hello guys,
I have several Onions in my house now doing many things. I wanted to do some sort of distributed control setup but things are getting a little difficult to manage.
I am now implementing a central control in my OpenWRT router. I am using one of the omegas to relay commands from the internet (Onion Cloud) to the router via sockets.
I have thought of several alternatives, pagekite, etc..., however the Onion Cloud seems to be the best thing I can think of right now. Can I add my OpenWRT router to the Onion Cloud? Is this allowed? I have 3 (soon to be 5) devices in my house connected to the Onion Cloud. I would much rather connect 1 (my OpenWRT router) to the cloud and manage the Onions through that. Is it at all possible? (the answer to this is probably yes, but the real question is...) Is it allowed?
Thanks!
Kit,
Thanks, I see what you are saying! Thanks for taking the time to explain.
The actual dimming, I plan to do it through an app, no button input.
Kit,
Thanks for your reply, I am sorry but I don't seem to understand though... If I common up the GPIO's to one pull up to 3.3V, then I can individually use a reed to pull the GPIO down to GND, so just one resistor should do no?
I am sorry to be a bother, just can't seem to understand why the case is that you need more than one resistor.
Hello guys,
Quick question, is it necessary to use one pull up per GPIO? Can I use one for many GPIO's?
Any reason as to why if not possible?
I am trying to pull several GPIO's up to 3.3 since the switch (reed relay) is N.C. to GND is this the best way to minimise power consumption? (I know it is not much)
Thanks,
Sam.
Hello guys,
I am trying to set up a dimmer device to do something similar to this:
https://plumlife.com/
Any ideas on how to do this with an onion? Is it possible?
@Lazar-Demin I am cross compiling on my own. I need to cross compile libweave for the onion. I did not, honestly, think of using the cloud app. Would this be possible?
Ok, so I tried, but no luck cross compiling. I think I must be doing something wrong. To be honest its not that big a deal for me so I am not really willing to spend much time on it. I will just be on the lookout to see if someone else does this.
Any news on how this is coming along?
I am going to take a crack at it this weekend, if anyone has any news/ideas it would be much appreciated.
I am simply going to use Weave, not Brillio, and see where that gets me.
I have used Automagic very successfully to create an "APP" to interface with Onion.
Automagic allows you to create widgets and a basic UI, and through the use of onion cloud you can control the Onion as well.
I use json in python to create a json file that outputs all the variables I wish to see on my phone. Automagic can decode json to get at the variable very easily as well.
The best advantage of Automagic is that you can change the way things work "on the go" without needing a computer to compile, etc... Thats mostly the reason why I chose to use Automagic rather than write my own app.
Here is a thread that might help:
http://automagic4android.com/forum/viewtopic.php?f=5&t=5866&p=14527&hilit=omega#p14527
I would be happy to post my flows and widgets as an example if somebody is interested.
Regards,
Sam.
Its funny how things worked out. I did think about getting another relay to activate with the relay expansion relay but in the end I decided that would beat the purpose of a relay.
I did not think of replacing the relay expansion relays. I think that would be a good way to go if I see more problems in the future.
Thanks again everyone.
Ok, I had a chat with my father, who is an old engineer and used to work in BT in the 50's, he told me of a trick they had back then. Apparently they let the relay weld and would "unstick" it, and do this a few times. He claims this would even out the surface and create a bigger surface of contact so less micro-welding.
Odd no?
Well, I tried this, and after 5 or 6 times the relays no longer locked!
All is well now 
Thanks guys.
