$8 Lamp (Outlet) "Smart Plug" Module

[petewill]

@znikos Yeah, I did connect it to the outlet but maybe I forgot to mention it? Oops...

Thanks @ServiceXp!

[blacey]

Sweet! :)

Very nice video! Thanks!

[gigi]

Nice project!!!

[Dean]

Thanks for sharing your video! I just finished watching it and I feel like I just learned more in that time than I have in months! If you can't tell, I am a bit of a visual learner :-) It was really helpful to be able to watch the whole project come together from beginning to end.

[petewill]

@Dean glad it could help! That is exactly why I made it like that. I know it will be too long for some people but I remember it was difficult for me to piece together all the steps when I was first starting.

@petewill Great video when are you planning in doing the power monitoring for this project?

[hek]

Excellent @petewill.

Your video has been added to relay build page and in the news section.

Great work!

[petewill]

@Francois great question! To be honest, it's on the list but not very high. I have a few other projects I wanted to do and hopefully create videos for.

@hek Thanks! You have created something awesome and I am excited to give back just a little when I can. Thanks for all you've done (and continue to do)!!

Nice project.

I will build some plugs myself, but I would like to exclude the charger, we should be able to power the arduino directly from the ac plug.

I am thinking to use something like this

What do you think about it?

That looks like an "charger" just in another package :) in my opinion it's a bit over the top, with a 10W power supply, to a device that uses arround 0,5W (0.1mA @ 5V) in peaks.

Hi,

Sorry I Think I expressed myself to short and incorrect on my way to work.

I really like this Project. My personal problem is that when you have many sensors, sooner or later you run out of old chargers ;)

Therefore for the relay (wallplug) it would be nice to find a small ac/dc power supply, which is easy to integrate into the breadboard/pcb.

The Meanwell that I linked to i also availible in 5w, but personally I had some problems in the past, with the current consumption of the relays, using sub wall-warts. This is why I am thinking 10w.

Mean well have nice quality but pricing is quite high. Would be nice to find an alternative with enough quality that you can trust that it wont burst into flames.

Edit: Mybe this tread is the correct one to discuss ac/dc converters. http://forum.mysensors.org/topic/687/230v-power-supply-to-arduino

@johnr It doesn't look like that series has any temperature protection??

[johnr]

servicexp, no I guess it have only over current protection.

I am going to test a smaller 5w converter. MW irm-05-5 which I was able to get for a ok price through work. It has also smaller physical dimensions.

Nice, let us know how it works! I also find I run out of chargers. Thankfully I can get them from work occasionally when people recycle their old phone chargers.

@petewill

Or hotel lost and found...

[petewill]

@BulldogLowell yeah, good idea! I wonder if electronics stores may have them too. I know Best Buy has a electronics recycling program. Maybe they get them there too? I just got a fresh supply from work so I should be good for a little while :)

[Mohsin Hassan]

Hey Hi. Awesome project.
Just a quick though, could i just a Pro mini 5V and skip the whole voltage regulator part? or would that need some additional changes to the project?

Thank :+1:

[petewill]

@Mohsin-Hassan Do you mean a 3.3v pro mini? If so, then you should be able to. The radio requires 3.3v to work. You would need to take the 5v from the phone charger to power the relay.

@petewill

Hello, how are you?
Man, I understood how you do this project, but Have one thing I doesn't understand, How you sync the plug with your cellphone?
Because intro the plug have a Arduino and RF Module.
Could you explain me?
Thx :)
