is i t working model

The PCBs are not finished, I still have to try the signature chip and the flash chip, I also need to try the RF communication using the MySensor library, with other libraries it has worked well so I do not expect surprises at that point.

I'm waiting for the MDMSGate gateway to arrive to finish the tests, and the new angled connectors to make the PCBs again.

Except for those points that need to be tested, everything else works correctly. Now I'm going to make the new box, it will look like this:

Today I received the Gateway MDMSGate and the touch switch works correctly, interacting with all the sensors of the node. This afternoon I will try the FOTA updates.

@giltesa
Having customized the CS pin of the flash chip, the bootloader should not know the pin.
I have to compile the bootloader with the correct pin.

Edit: I've already got the FOTA updates working, later I'll write more information.

Hello @giridhararm,

In this version of the PCB all the features work correctly, except the signature that I have not yet tried but should work without problems.

You can manufacture the PCBs, although my recommendation is that you wait (it will take several months). A problem with the current version is that once the cables are screwed to the switch, it takes a lot of effort to place the switch in the wall box because the cables rub against the box.
That's why I bought these connectors with superior insertion of the cables, and redesigned the 3D model:

It is possible that I also change the pinout of the microcontroller in the next version to take better advantage of the PWM pins... I still do not know if they are necessary to control a Triac, in case of not being necessary I will leave the flash chip in its original pin and connect the blue led to a PWM pin.

Edit:
I have cut with the Dremel the holes in the new position (they are deflected towards the inside of the plate 1mm) after the welded the new connector, it is perfect!

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.

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

It seems that the new node works perfectly. Soon I will update the documentation.

Hi @talhatec ,

The remote controls work well. 4 months ago I installed a new battery and from time to time I press the button to check if they continue with battery, they sleep correctly.

I remain pending to change the RF antenna for a better one and to improve some failures in the connectors of the battery that at the moment are very fragile (the pad has little copper).

The casing can be purchased online

For now the project is stopped, I want to test the Aqara sensors (I buy them this week), in any case the domotics is now my lowest priority.

@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.

@kalina
The PCB looks very good.
I thought you soldered the PCBs manually. Where do you order the assembly of PCBs? Price?

Hello @kalina

It looks very good, but why do not I use a DIN rail box?

For example:

@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.

@marcusakamg7 said in Wireless Touch Switch: Relay Model - (For Livolo crystals):

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:

@kalina

I find it surprising that without writing any line of programming code, apart from the constants, the MySensors library takes care of everything, it's great!

My intention was to change the channel of the NRF24L01, the transfer speed, and configure the ATSHA204A.

I think I read that the MDMSGate does not support MQTT because of hardware stuff, do you plan to release a second version?
The truth is that I am not sure that it is essential either, but I ask you out of curiosity.

Edit:
More questions...

Why is the sketch configured with MY_RF24_PA_LEVEL = RF24_PA_LOW? Would not it be better to use the value RF24_PA_HIGH or RF24_PA_MAX?

Hello Kalina,

On April 7, I presented my domotics nodes at the Arduino Day in Zaragoza, Spain. Your gateway worked all day like a champion!
https://giltesa.com/wp-content/uploads/2018/04/ArduinoDayZgz2018_stand.jpg

I have a question, would it be possible to get the Arduino sketch that has recorded the Atmega328P?
Is this code? Do you only need that to work for NRF24L01+Ethernet?
https://github.com/DmytroKalinkin/MDMS/blob/master/Gateway_2.4GHz/Gateway_2.4GHz.ino

Kind regards.

I have already published all the documentation, on my website, GitHub and openhardware.io
For now I leave the node as finished.
