$8 Lamp (Outlet) "Smart Plug" Module

@andriej
I have a raspberry, but I think use only arudino.

therefore I try make a device similar to vera :/
Could you help me?

Unfortunately I don't know how to do that. The best thing I can suggest is to use one of the existing controllers. If you already have a raspberry pi there is free software for it. Try one of those. That way you don't have to recreate anything.

@petewill

Hmm,
Okay, but I think I don't understand is how I will do the communication between getway ethernet and another device.

You probably want to check out this: http://www.mysensors.org/about/ and this: http://www.openhab.org/

It will will take some learning and I suggest you start out small. See if you can get OpenHab up and running first. When you understand that you can start using MySensors. I had my Vera for a few months before I started learning MySensors. It was helpful to learn the controller before MySensors.

Thank you very much for detailed description!
But I cannot understand how to send commands from OpenHab to turn relay on and off. Please direct me.
After a long time I can finally get the messages from sensors via serial connection, but not the other way.
Cheers!

@almj I use Vera as my controller so I'm not sure how to set up OpenHab. I know there are some instructions for setting it up here on the forum. If you're still stuck you may get better responses by posting to a new topic. Sorry I can't be more help.

Is it really that difficult or expensive to get old chargers?
I found 10 for $10.99 on ebay.
:stuck_out_tongue:

[petewill]

@bytedeez Nah, it's not that hard or expensive. It's always nice to get them free when you can though :)

Hello,

Which is connected to the relay in the diagram???

Thanks,

@Douglas I just used the standard wiring from the build page here: http://www.mysensors.org/build/relay

Hi @petewill!
I made this :) Great video :+1:

I think i get bad reception or something because it works the first 5-6 times and then nothing...

In the end you describe an cat5 wire added as antenna because of bad reception.
Do you remove the plastic/shielding so its just copper?
Im afraid to short anything out with a long uncovered antenna if thats the case...

and if i hear you right its 3,28 inches which should be 33,31200 millimeters on the antenna?

This could also be a power or a wiring issue. But, the antenna is an easy modification so it wouldn't hurt to try this first. Another test is to move the device closer to your gateway. If it still stops after 5-6 times then it probably isn't communication issues.

No, I left the shielding on the wire. Sorry, I should have specified that.

I think 3.28 inches is 83.312 millimeters (at least that's what google says it is).

I have these lockups all the time and have not been able to get rid of them. I tried:

• separated power supplies
• capacitors
• shielding

Most probably (in my case) is the spike introduced by the coil of the relay. This somehow puts the radio in a sleep (or half dead) state. By moving away from mechanical to triac (ssd) 'relays' I was finaly able to solve it. If you find a solution please post.

[sundberg84]

@AWI Hmm, ok... will give it a try and report back if i find anything...

It seems to be both range and spikes? The sensor works great without anything connected to 240v out but as soon as i connect anything like a lamp it fails within 5 on/off. Also when i move it close to the gw but then atleast it works without any 240v connected.

The SSD relays, is that something like this?

Any downsides with SSR relays?

[AWI]

@sundberg84 I have never found these before. Sounds like an interesting option. Made myself boards like these
The 'downside' of these is that there can be a leak voltage when the output is left open.

[sundberg84]

@AWI Your link didnt work (typo)
Ill give these a try and let post if they are any good.

Strange. I have been using mine for months without any issues. It is triggered by motion in my family room so it is used every day multiple times. Were you powering the relay from the Arduino or directly from the 5v?

[sundberg84]

@petewill In my case from VCC from arduino. I try to change incoming to raw and see if that makes any differens.

Yeah, let me know. It's been a while, so I don't remember what project I had issues with, but I had issues with power when I was using the Arduino 5V. I always try to pull power from the source (not Arduino) whenever I can now. Hopefully this will help your issue.

[sundberg84]

Now the relay powers up, and i can switch (led turns on) but no click/coil activation so no 240v power out. Changed the relay but same result. I have 5v relay vcc and 5v on in but nothing... strange.
