110v-230v AC to Mysensors PCB board
-
@aproxx : of course I am interested with your files. It could be useful.
@axillent : when you say 2-wire lighting, do you mean for one main??? I have done some tests last month to make something like fibaro fgd211. But I jumped onto another project. I had problems I remember. To test I was using a little china transfo and incandescent bulb. First test, zero cross detect with triac. Arduino rebooted always at start (I think about drop voltage and brownout reset arduino, because of a reset of the transfo. but not sure it was that, or maybe it was a no good zerocross....). Then I tried with mosfet pwm. Arduino booted right, but when I increased pwm to something like 192-200, arduino resetted. So I was thinking to use lnk306 but no time (and I think lnk306 need same input voltage so I don't know if it could resolve the problem. So I now am thinking to disconnect my light network and connect it to dc 48 and using led instead.
Do you have idea, to power (steal energy) nodes with one main??? -

If you have a look at the datasheet you see:
All voltage input (AC: 90 ~ 264V)
110 should work.

@Andreas-Maurer Thats Great. You may want to change the title to reflect that.

@scalz
May I make a suggestion? I would look for a solution for both 230v AND 120v for us yanks.. :-) I know I would make the purchase. -
@scalz two wire ligting menas that a wall switch is feeded only with two wires. One wire is a L source and second wire is from the load (from the lamp). Classical switch just need to short this two for the light to startup. In this case ay smart switch need some advanced technique on to power itself. For example fibaro dimmers do so.
Do you plan to use single 48V power supply for the lighting? I'm working on the prokect for the guest house because it is just on building stage. I have a plan to use single 48V AC-DC power source with wired mysensors network. I will use 3 wires accross all lamps and switches and sensors. They will communicate with each othe P2P using a single wire interface based on Manchester encoding. I also plan to have Mysensors gateway.

@axillent Ok. thank you. At my home it is like that. sure it needs a smart switch. and fibaro seems to be very smart (very small, small transfo, and steal energy, but z wave so I think it may use sync comm to use less energy. Maybe I am wrong and don't know how it is inside).
You are right. I am thinking to use 48v power supply lighting. But I cannot change my electrical network. So two wire. And I hope it will be easier to steal energy and power the in wall switch node for leds. Maybe I am wrong. I will power my lightings with energy harvesting (solar, or maybe I have another idea but i have to make experiments.Your lighting project is very smart too. can't wait to see it too.

@ServiceXp : are you talking about my relay board? if yes, I will check what I can do in the end of the week and post my project in a new topic (I think I have to rearrange the board to fit the step down).
-
@ServiceXp , I'm also looking for a way to power a node from the available-standard two wire switch. It should be possible to steal some milliamps from there, but I don't know even from where to start researching it.

Hi All,
I'm not sure if I understand the 2-wire thing completely, but in my house (which is kind of standard I guess in Europe) I have 3 wires going from the electricity cabinet, to the light switch and then to the light bulb. These cables are Phase, Neutral and Ground.
As I don't want to rewire my entire grid, I decided to build these boards so I can reuse the current wiring. I ended up with the following "schematic" if I can call my paintskills like that.
The enclosure at the bottom of the drawing would be placed behind the current light switch, while the enclosure at the top of the drawing would be placed right above the light bulb. This requires little to no modification of my current wiring.
@ServiceXP, I'll update the title to include the 110v information.
-
Why don't you place the relay behind the switch, too? This way you could save half of the nodes.
I have just ordered some of those power supply modules. Very interesting, cheapest similar ones I found before were about 14 €.

This is what I have done for a light bulb in the pantry with a motion sensor. Its a mess as it is a proof of concept.
I have a 5 separate "modules" as such. Arduino Pro Mini, Motion Sensor, Radio, 5V AC/DC transformer and a 5V Relay. So clearly it is too big and a bit of a mess! So I am really interested in your PCB @aproxx! Do let us know how it works for you.

There is something similar I'm working on. Although mine is more like a solid state relay. And it can be used as an AC dimmer. But has the same concept with AC-DC converter. I used one from Vigortronix. It has a 3.3V output.
Here it is controlled with Bluetooth serial connection
This is how the board looks like
If anyone wants it, let me know.@aproxx I like your form factor. Great find with that AC-DC converter.
-
Those are even much smaller (3.3v , 25x38x17 mm , 3w) and have similar price. I've got one (still to experiment with)
-
Too bad these Ac Dc are so expensive and little big. But good quality for sure.
@ceech : looks like a pretty board. I am interested in your files please. It could be useful..:wink:

thank you!
