💬 AC-DC double solid state relay module

Nca78

Very nice project. I would like to have access to few more pins to add some functionality like motion sensor, and light sensor. Of course those would be outside of the wall :)

Hello, I would not advise to use this board with sensors accessible to fingers. The spacing between main voltage and low voltage traces is too narrow at some points on the board and a short circuit is possible. It is fine/safe to use only in a closed box or connected to wall switches as they are designed to be safe with main voltage.

I think that woundn't be so risky becouse o think about mounting it not behind light buttons, but in this box just below ceiling(where wires crossing their paths), this box is placed more than 2 meters above floor level.

Still a bit, no ?
Anyway if you have requirement for a board that would be both easy to solder and safe even outside of electrical box, can you send them to me by private message ? I'm working on such a board and I'm opened to any improvement ideas of use cases that would not be filled by currently available boards.

I've just thought about little node that could be mounted in almost every room, and be barely visible. This box below ceiling is quite good place for this. I have plan to do something like dome(3d printed) instead of flat box cover to fit electronics there. As i told in previous messages i would like to have node that could turn on/off light, read temperature, movement, and light level by LDR.

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 crash server :flushed: now i cant

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.
