Hello, for information, the version has changed :( Here is the new board : https://fr.aliexpress.com/item/Free-Shipping-EU-Standard-Livolo-AC-110-250V-The-Base-Of-Wall-Light-Touch-Screen-Switch/1898648882.html
But there is good news, 3V and 12V are directly accessible ;)@tonnerre33 said in 💬 Livolo EU switch Mysensors integration:

But there is good news, 3V and 12V are directly accessible ;)Might be bad news in the (very) short term, but it will soon be much better as it means after modification to adapt to the new version @mtiutiu board should not require any hardware modification on the main power/relay PCB as 12V is now available.

Well..I was expecting this to happen at some point in time. This is the nasty thing that may happen when you rely on some external board(s) to do your work. It is a good thing that the 12V line is now exposed..but the pcb needs to be recreated.
And who knows in the future when it might change again. So in the end the best solution would be to have all the boards made(including the power/relays one) so that no one needs to rely on the Livolo company. But for the moment I don't have enough knowledge/time - at least not too much regarding power electronics and creating live wire only power supplies(including testing/safety/etc). -

Hi,
Because some people asked here: I don't have anything for sale unfortunately and I don't have time to produce and sell ready made boards. The project design files are available for free so anyone can build it. But be aware that you need to have the right livolo switches(as seen from the project pictures). Latest ones produced by the Livolo manufacturer use another hardware revision which is not compatible with the pcb that I've designed.
Regarding BOM and total price for producing one board I didn't had time for that either and the thing is that the price varies depending from where you supply the components.

Hi @mtiutiu - Firstly nice work. I bought a few and sent on a little gratitude also.
Is there a revision or something on the lenovo switches to make sure that I have the right one? I have quite a few now and a few more on the way so I just want to make sure I am all set.
Thanks!

@mtiutiu Thanks for the quick response, can only eat PCBs without components? I can not make a PCB.
Few weeks ago I uploaded and shared to Oshpark pcb web service this @mtiutiu pcb design (but take care !!! I think this is not last one version @mtiutiu design), so anyone can easily find it there and order build some pcb if like.
You can check it at https://oshpark.com/shared_projects , and easyly find it with only enter "livolo" word in the search case.
Sadly I don't have enough time yet to involve more in this project, but in near future I'm going to that and test that awesome design that this project have.
Regards

@jirm The differences between the hw designs that I made are very small and have no impact regarding the final functionality of the board(the OSHpark version is ok too). The biggest change was to trim down a little bit the round corners of the board so that it fits from the start inside the switch case(otherwise you need to use some abrasive paper to trim it a little bit - but not much). I also added a ferrite bead to filter high frequency noise that may come from the dc-dc switching power supply and replaced the important filtering capacitors with tantalum ones(but the old board revision model can be used also to solder 0805 type tantalum caps as the footprints are large enough).
@shabba VL-C700X-1 Ver: B8 is the hw revision of the Livolo switches that I have. But this is marked on the power/relays board from inside and not on the enclosure. So in other words you can see that revision only if you open the switch. Otherwise it's impossible to say as the Livolo manufacturer sells it using the same model number(like VL-C702 or something like that) but the hw revision can be different and can only be seen inside the switch. You can see the board that I have by inspecting the pictures posted on the project page.

Crap! I have version C2. I have already ordered all the BOM components! Doh.
Can the old PCB be hacked into working with this? What is the actual difference?
Thanks!
Can you post some pictures of the new board? I'm curious how it looks on both sides. I'm referring to the power/relays board underneath. I may need to recreate this project board after the new one because my friend for whom I made this project initially bought the new version of the Livolo switches. So in the end I think I'll work on the new version but only after he receives the switches as I need to compare and see the differences from both a mechanical and electrical point of view.
Don't worry about the BOM as that part stays the same. What could change is only the PCB layout and its size and/or outline. -

Can you focus a little bit better on the power/relays board? Those pics are a little bit blurry. Thanks. Oh..and I almost forgot - thank you for your gratitude.
The main change is that they added a 2x7 connector now instead of the old one which was 2x6. But that's not a big problem at all as I can recreate the PCB to accommodate the new one. Still I have to wait for the Livolo switches to come in my hand so that I can identify the changes regarding the new connector(where the relays are connected and the 12-14V line if any). Other than that I don't see any big changes only the rounded corners are not so round now and they have a cut. The MOSFET is placed now at a 45 degree angle and the relays driving IC is a TSSOP one if I see well in the pictures. The 3.3V or 3V regulator is placed somewhere else now but that doesn't matter as I don't need it.
So in short: I need to recreate the PCB to accommodate the new 2x7 connector and to add cuts in the corners. BOM will not change.

@mtiutiu It's the PCB that i made here : https://github.com/tonnerre33/Linovo_EU_2Gang_1way/tree/develop/
You can take many informations that you want ;)
I'm curious to see how you'll do the pcb for compare with mine and learn ;) -
