livolo Glass Panel Touch Light Wall Switch + arduino 433Mhz

[Hugo Pereira]

Hello everyone,

I am really sorry if I am here making an entirely noob question, but did someone managed to get the light state from this light wall switch? If so is there any video or circuit showing how? I have doubts if i should or should not buy this for my entire house, but if this wall switch cannot send the state through rf i guess it is a no go.

Hope you can help me

Hello, by default it is not sending the status by radio (which is used for receiving only).
But I think with the modifications you can see earlier in the thread it can send and receive using nrf24/mysensors. These are based on the basic switch without radio, no use to buy the much more expensive radio versions when the radio will not be used.

I'm using a different approach which is to replace completely the PCB, so there are no modifications to do to the "main power" part, just plug the new touch PCB (that includes logic and NRF radio). I'm doing it for another switch format (US/AU) but the logic is very similar in EU format switch so if there is a demand I will adapt my PCB for this format later.

@Nca78 Very interisting if the prices are the same and the design! You have a buyer :P Hope you ship to Portugal eheh I will be waiting for your solution for EU. Cause honestly i did not wanted to make too complicated adaptations on the circuit.

I think you misunderstood :P
I'm making only the PCB (electronic board on which to solder the components). So you still need to buy Livolo switches (with no radio) and then get my PCB done and solder components on it. Then replace the touch PCB from Livolo switch with it.
It won't be very expensive (about 5-6$ of parts per switch I think) but there's some work to do :P

Hi, I'm working on this one too. This Livolo stuff captured my attention a long time ago as I needed an in wall solution for controlling the lights(without using batteries and such). I wanted this to be integrated with the existing infrastructure also(the existing house electrical wiring for lights). I studied the power supply part before the Livolo switches era as I wanted to make one of my own but in the end it seemed not so an easy task because of the series circuit( to take power from the live wire only). Anyways if the power board from the existing Livolo switches will be capable of delivering the required power it will be really awesome(as the non radio switch is really cheap
).
In my case I'm using the rfm69 module(the CW variant as it's more compact) which requires a little bit more current(45 mA or so). I don't want to use the existing 3V line which the Livolo power board has because as I've seen from this thread pictures and schematics it uses a low current voltage regulator(30mA max or so from my investigations). This is fine for the nrf24l01 low power variant but for RFM69 it isn't. So currently I'm working on identifying the 12V line as my design uses a buck converter to get it as low as 3.0-3.3V.

The project and progress is posted here: https://www.openhardware.io/view/306/Livolo-EU-switch-Mysensors-integration. Depending on my free time I will continue to work on it but I don't know when it will be finished.

Keep up the good work and congrats to the Mysensors creators for this wonderful project.

Hello, on the US/AU version there is a 12V pin on the 2*7 connector. It's opposite the GND

сегодня доделал Livolo+esp8266 пришлось помучаться с программой и схемой питания но все заработало[0_1485259118390_livolo_esp.mp4](Uploading 100%)

@DJONvl
Woow !
Livolo+Esp8266 working ??? ... sounds very good.
But we can not see the video seems you try to upload here ... :-(

@DJONvl

Yesss @DJONvl . Thats is !!!! .
You got it !!!

Please can you post all the details about how you are do it ??

How you are managed to achieve enough power from Livolo ??

How you wired the esp8266 and where on the livolo switch ??

You can post the schematic ??

Please, all details you can...

Regards

@DJONvl
Esp потребляет более 350мА.
Покажешь схему питания?

Esp consumes more then 350mA.
Can you show power schematic?

For the AU/US plate, can anyone confirm that this is the correct wiring for
SW1 = Switch Right on/off
SW2 = Switch Left on/off
SS1 = Right Status on/off
SS2 = Left Status on /off
GND = Ground

[Markhill]

For power, I found these on the board. The 12V accutally read 14.86V for the two Switch gang and 14.10V for the 1 gang switch. This was me using the multimeter connecting with ground.

1 Gang Switch even have indication of the board

2 Gang Switch

@Markhill for switching on/off the relays it's not that simple. On the 'main' board there is a decoder connected to 3 pins or the MCU and on the 2x7 header.
Check in one of my messages above for the pin out on the header.

@Nca78 Hi, I was thinking of using this to connect to the switch. The guy sell this for about $15.00US each

The controller require external power 5-12v. I was thinking of using power from the switch.

[Nca78]

@Markhill it cannot work, this board needs external power because the ESP8266 he is using is too power hungry, the switch cannot provide enough power. And this board is sized for EU switch it will not work with US or US/AU switch.

I'm working on 3 buttons and 4 buttons version with atmega and nrf24, power from the swith is enough so it's just a plug&play replacement. I'm testing the 3 buttons switch at the moment (same layout than 1 button in which only the center button is connected). It will be cheaper than 15$ if you solder it yourself, if you don't want to do smd soldering we can probably find a solution for pre-assembled boards.

[Markhill]

@Nca78 I'm in. Plug and play, same size, no external power and cheaper too. When will it be ready?

Btw, your board will be able fit on a 3 buttons and 4 buttons too right? I got them.

Will it provide status feed back, control remotely on phone app or ioBroker and is there any coding required?

[Samuel235]

Keep us updated on your development, i'm working on a double relay module for lighting but i doubt its going to fit inside of a single gang wall box.

[Nca78]

@Markhill I have made 2 boards, one for 1/3 buttons, one for 4 buttons.
It will be a MySensors actuator so yes status feedback etc.

I'll make a script for basic switch function and probably a few extra things two. I'm planning to use 3 button switches in my home to command 2 light circuits with the top and bottom buttons, and AC with center button (not using the relay). I have included 2 extra leds on center button for that, to select different modes of AC.

The 4 buttons version uses sx1509 extender to have more advanced feedback like breathing/flashing LEDs but it's probably not in a final form yet, it will take more time to be ready.
