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.
