$8 Lamp (Outlet) "Smart Plug" Module

Hi Pete,
I'm new to this forum, but I wanted to give you a big thumbs up. I really enjoyed watching your videos and I learned a lot from watching them. It's because of people like you that made me decide to start using MySensors.
I have an old 433Mhx power plug that is broken. I see if I can turn it in to a MySensors power plug ;)

@Zeph I agree. This is complicated stuff that I don't even begin to grasp. That said it is a cheap and easy hack to try. In my case it has helped every time. Maybe I just got lucky but it helped enough of my nodes that I thought I'd at least tell people about it. If it doesn't work, then just remove the wire and no harm done. Thanks for all your contributions to the site. Your knowledge is helping a lot of people.
@TheoL Thanks for the kind words! Although, credit really goes to @hek and the team. They are the geniuses that make this all work! Good luck with "mysensoring" the old power plug. But, be careful, it's addicting. :)

@petewill just to be clear - I appreciate your posting that adding the loose wire to the on-PCB antenna helped, and I'm not discouraging that. If it works, it works! Mostly I wanted people to understand that it's going to be trial and error, rather than something where they can count on calculating the best length (because it's added to another antenna at an unanticipated point, rather than being a standalone wire antenna). It would not surprise me if somebody found that a 6.5 cm wire worked better than 8.33cm, for their particular case (picking an example length at random). Wiggle those rabbit ears!
I love the examples you post and your excellent videos. I have modestly good knowledge here and there, with gaps in other places, and your working examples give me confidence/inspiration to build something I haven't before - along with practical (not just theoretical) advice. You even turn your minor mistakes into lessons - how it should have been done, and how you managed to work around it anyway. Keep them coming!

I agree. The more knowledge provided to people the better hopefully it will result in better communicating nodes. Thanks for the posts!

@petewill Off course I'm very gratefull for what @hek and the team created. I've been playing with mySensors for a week now. And I'm still amazed by it. It's so easy to use. And I haven't had a failure yet. I'm currently promoting MySensors to everyone I know ;-).
@hek Do you happen to have some small stickers with the MySensors logo? Ik would love to put them on the sensors I create. Something like "Powered by MySensors"?
-
I like the idea of logo stickers. Better in some ways than typical swag like t-shirts and coffee cups, because if it goes on the devices we build that provides useful information, not just advertising. Maybe leave a blank section where a node number could optionally be written in with a sharpie, or a version.
Maybe "Networked by MySensors.org" rather than powered? ("Telepathy by MySensors"?)

Dome Stickers would be nice ;)

The domes are kind of cool for some things, but I think for this purpose I'd actually prefer flat stickers that fit smoothly on any side of a project box, even curved, without protruding and looking like something that should be pressed, or that should light up.
(OTOH domes atop an illuminated button (assuming translucent backing) would be awesome in some cases)
And with flat, (re) distribution in small batches is easier - one could get a lot of them in a minimum-postage conventional letter.

Hi Pete,
I'm thinking of using the AMS1117 3.3v regulator. Can I still use the 0.1uF and 10uF capacitors or do I need to use others. Because I run into sites saying I need to use 100uF and 1000uF and I think the difference is pretty big.
Regards,
Kenney
btw: Great video! It helped me a lot!!

Yes, that should be fine. The capacitors are there to help filter the power to the radio (which can be sensitive).

Regarding adding wires to the on-PCB antenna of a nRF24L01+ module, here's someone who used two wires (andcut some traces) to create a dipole. He knew that it was hard to really calculate the appropriate values, so he did empirical testing to find the best lengths, using a test program.

And is this from the same Pete or another one?

Another interesting (albeit long) video testing range of various modules and antennae.
https://www.youtube.com/watch?v=gtM832Z0ujE
The interoperability of different types is somewhat surprising. Some had only a 2/3 packet success ratio even at close range, but retained that for a long distance, for example. He did try cap vs no cap, and with "whip" (really more of a stubby or rubber ducky style) antenna parallel or with one pointing at the other. The unit with PA+LNA and shield was overall pretty good for range.

@petewill
Now i got three working relays thanks to you, so again, great video!
Wanted to thank you and also show my sollution.
I hade some 433mhz cheap (not good working) relays with perfect case i could re-use:
The case had a status-led and a switch i use as well.
@sundberg84 how are you powering the arduino?
-
@dayve218
Im using a USB charger as pete does in the video but mine is a iphone charger instead of a samsung. -
Nice project, both Petewill and sundberg84.
I was just wandering if you @sundberg84 know more about what is the device type/model/manufacturer you were moding?I've used quite some time and effort to find localy some good case that I can modify, I did manage to hack some of them but they are just not quite reliable (something with power just kills caps too often).
Thanks in advance, sorry for bringing up old topic (but it is a very good one :) )

@dakipro - Its a low brand 433mhz wall plugs i bought in Sweden called Everflourish emw100r. I dont think they are sold anymore. Its probably some china brand so maybe they are sold in another name.
