💬 AC-DC double solid state relay module

Hello.
I would like to ask whether it is normal that the switch does not work if the server domoticz off? I want to use the switch only when I have a server crash and now does not work.:flushed:

That's a problem of MySensors, if you don't have physical switches connected directly on your node you are depending on a functionnal gateway/controller to run... That's why I'm going more toward the "upgraded" livolo-style wall switch now, even if the radio is down you can still maintain basic functionality of the switch. This board can do it but you need to have neutral wire in the switch box which I don't have :(

@okos Unfortunately current mysensors version won't allow to 'boot' your code before their module connects to a controller. This is a main reason I moved to ESP8266 hardware.

It does, you can put a before() method in your sketch.

You can disable this behaviour by defining:

#define MY_TRANSPORT_DONT_CARE_MODE
#define MY_PARENT_NODE_ID 0

[okos]

Thanx for the answers
This is not good news from the switch does not work without a server. Mr.const, Do you use esp8266 in domoticz to control the light?

edit: hek, I not noticed your post.
What changes adding this?

#define MY_TRANSPORT_DONT_CARE_MODE
#define MY_PARENT_NODE_ID 0```

It disables the transport sanity check at startup.

This is a really good news, I'll give it a try to check if it works correctly with controller and when controller is lost.

sorry for the ridiculous question but I have to enter into a sketch? or MyConfig.h?

[hek]

In the sketch before including MySensors.h

Tried it. Doesn't work. Btw, I searched all mysensors sources (2.0) and didn't find any use of a MY_TRANSPORT_DONT_CARE_MODE definition.

MY_TRANSPORT_DONT_CARE_MODE

Sorry, yes, It's all in the development branch:

https://github.com/mysensors/MySensors/search?utf8=✓&q=MY_TRANSPORT_DONT_CARE_MODE

[okos]

It possible implement this option in mysensors 2.0 ?

[mfalkvidd]

@okos it will be included in the next release yes.

Hello.
I tried to upload my two boards ( arduino pro mini 8Mhz , 3,3 V ) modified sketches but returned to sketch Nca78 (with DS18B20), unfortunately, does not operate a physical switch. Sometimes phisical switch changes state in domoticz ( not every time ) but relays do not change state.
Switching on and switching off the lights of domoticz changes state relay without a problem.
What could be wrong ?

Hi

Does somebody can post a picture of the back side please.

Thinks

@ludoarchi ![alt text]

[ludoarchi]

@okos thinks !

[Nca78]

That's where the biggest problem is on this board. I think the previous revision without the DS18 is safer, here there is less than 2mm creepage/clearance between main and low voltage traces and solder points, not enough :(

There's also problem of mixing both main/low voltage everywhere in the board like near the NRF24.

Hi
Noob questions sorry !
1/ Can i used it with 3way switches ?
2/ what are the pins 7 GND and 4 for ?

7 and 4 pins are mapped to 7 and 4 in/out of an arduino module. GND is for ground. These pins could be used to manually control relay state.
