💬 Wireless Touch Switch: Relay Model - (For Livolo crystals)

[TeT]

Hello! Realy good job!
Dimmer good idea too. :+1:
Did you plan to do livolo two gang ? and roller shutter witch current detection?

[giltesa]

Hello @tet

This circuit does not allow to regulate the light of the lamps, the circuit that will allow it is this other (only changes the red PCB):
https://forum.mysensors.org/topic/8952/wireless-touch-switch-triac-model-for-livolo-crystals

However, as it puts in that thread, I am having problems with the regulation of brightness, today I have arrived a new Philips bulb and it works much better than the Ikea bulb however it keeps blinking, I am going to buy some new triacs and optocouplers to see if those work better.

As for your questions, I had not planned to make a switch with two tactile pushbuttons, I think it is uncomfortable to press when there is more than one pushbutton since you have to be aware of which area of ​​the crystal you press, however now you can press with the palm hand in any area to have a single button. In any case, doing that is not complicated and since I am going to share all the files, anyone can customize the plate to their liking.

Does current detection have utility? Is it to know the consumption of the lamp? If it is for that I do not think it is useful to measure the consumption of the lamps independently, I had thought to make a current measurement node that was installed in the electrical panel and there measure the areas that interested me, for example the kitchen.

Kind regards.

I would like to know if you plan to do a roller shutter node (for up and down store)?
current detection is to mesure the time to up or down the store. And calculate position in %.
2 gang one for up and the other for down :relaxed:

My idea is to design all the nodes that I need, for now I am developing these four:

Touch push button, relay type
Touch push button, triac type
Multi purpose sensor: Doors, windows, temperature, humidity, light, and three expansion connectors.
Remote control

When I finish them I also want to make:

LED strip controller WRGB 12V
Clamp sensor SCT-013 for electrical panel.
PIR sensor
Plug with relay
Roller shutter
Boiler control (or maybe buy it if it is compatible with the control software)

As you see my intention is to also design the node to control the blinds, I think the easiest thing would be to manufacture a PCB that is installed inside the double switch of the blind and activate the pulsations. I have not yet documented on how it works but I think that something like that should give good results, all the work would be done by the roller blind electronica, the node would only activate the button (with transistor/ssr).

I must also say that now I do not have a house where to install all these nodes so I am testing them in my test panel but not in a real environment...

[giltesa]

I just ordered to manufacture the next version of the PCB, actually I also sent to manufacture the other 4 modules.
When the PCBs arrive and perform the necessary tests, I will publish the updated files.

On the work panel and openhardware.io there are images of all the modules / nodes.

@giltesa Looking forward to seeing results! Great work.

[giltesa]

I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them.

Today the new PCBs have arrived, I will try to weld them this week!

By the way, I present the Wireless Touch Switch node to the pcbway.com contest and I won the third prize for best design :)

@giltesa Congrats!

Would this work in the US version light switch?

Yes, you can use it perfectly, both the power supply and the relays allow a voltage range of 90~264V and 0~240V AC respectively.

Edit: Investigate if the EU switches can be screwed into the wall box of the US switches.
I have used this standard size box:

[marcusakamg7]

well i mean i have livolo crystal (US) switch and was wondering if your pcb would work with it?

I notice the gang box is different in the (US) model.

@marcusakamg7

It is not compatible, you just have to see that the shape of the glass and the frame that holds it is completely different to the EU version, and if it was compatible Livolo would not have bothered to make several versions.

@giltesa where do you buy "HTTM light reflector"?

[giltesa]

@dzungpham0703

I buy them on Aliexpress:

If you apply hot air it is easy to take off the white "double sided tape" and the plastic.
