💬 AC-DC double solid state relay module
-
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 ? -

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.

hi, great project. I have one idea, is it possible to add current and voltage measurement ?
-
Ordered all the components for this project but now i see there are 12 v solid state relays on the list?? mine is not working, does it not need to have 5V version??
-
Hello,
one question to the SSR Relay. The Arduino works with 5V, the SSR in the BOM is a 12V type. Is this a mistake? According to the Datasheet of the relay, the 12V type has an operating range from 9,6v to 14,4V -
Hello all,
I have finished to assemble one of this board today.
You can see some pictures of my board here :

The skecth works fine.
Thx for this project.

I used the sketch of Nca78 (2 months ago) but i only command relays from jeedom.
I didn't test physical switch change because i don't have neutral wire in my switch box :( -

whose sketch you used? because I have a problem with phisycal switches if I use sketch of Nca78 (I wrote about this earlier)@okos said:

I'm not using the physical switches at the moment (same reason than tonnerre33, no neutral wire where I have put it at the moment), but I will try to find some time next week to fix the sketch. I'll fix the temperature sending too as sometimes I have some tiny variations of temperature that generate a lot of message sending in a burst and it perturbates other sensors.

Just a quick question before i order the PCB, is it realy 4.6x5 cm? (thats what it says on the dirtypcb website, but when i mesure the PCB in the diptrace file, it shows a perfect 5x5 cm.
can you please explain? -
PCB is 5*5cm.
You will also have to include the antenna of the NRF24 that is outside the PCB area.
