💬 AC-DC double solid state relay module

Sorry I forgot something.
For a 3.3 V Arduino we need a MOSFET or so to drive the SSR.
But there are cheep and small SMD packages available.@hugch no you don't need MOSFET for those SSR, the high level of input is below 3.3V. I've made a board with those and a 3.3V Arduino and didn't have any problem.
For this board it's missing fuses on the SSRs, if they fail and shortcut nothing will stop the short circuit at the moment.

@Nca78 My SSRs are with 5 V level but one with 3.3 V level would be better. You are right.
And the fuses are important but i think the step down have an over current protection, but a PTC could useful.
But a MOSFET or equal is also required:
It is not a good idea to drive current intensive peripheral directly with an micro controller.
The absolute maximum ratings for an ATmega328p is 40 mA. And a SSR is using 25 mA or so.
The better choice is using a driver or a simple transistor circuit.To drive the SSR directly would not damage the controller at this moment, but your are decrease the lifetime.
And the lifetime for an in wall module or so is very important. -
Hello!!, my name is Alejandro, I'm from Spain and I have been working on something quite similar to this project. I would like to contribute to reach a final design. What I have done until now is a prototype board similar than yours and I would like to add a top board with touch buttons to fit into Livolo glass panel switch.

My development is based on ESP8266 without rf communication but as I have progressed I have checked that Wifi connection is a complex system compared to rf so I am thinking to change to arduino or esp + nrf.

What's happening if you switch it on then off in domoticz ?

However, I have 2 remarks:
- Don't you need to set the pins to output before you set them low?
- You are not updating your gateway when you toggle the output with the switch.

hmm im having a hard time fitting these modules behind my lamp buttoms couse its swedish standar 70mm holes and the nrfmodule sticks out to much anyone know a good mod?

Hi everyone.Its me again!!!!
Everything seems to be working just fine when i am using domoticz interface, but when i am using the hardware switches the icons in domoticz update from off to on but my lights wont turn on. If i turn my hardware switch to off, the state in domoticz stays to on.What am i doing wrong????

I doubt anyone can help you without debug logs from your node and gateway.
You can also look at the logs yourself using this tool to see where messages get stuck or lost.

@hek the think is that the switch works using Domoticz, but when i use the pins for the hardware switch , i get the icons updated in domotics to on or off but my lights stay off
@johnym30 It might be the way the code is written in your receive function.
When you toggle the hardware switch a message is sent to your controller with the new state, so Domoticz will get this and change the icons accordingly. The message you sent also asks for an ack back, it is this returning ack that is used to switch the relay.
The first If statement in your present code captures the ack and does a serial print but then does nothing else, so your ack is ignored by the rest of the code. So your relay will not be switched.
I see no reason why you need to test for an ack so try the following code and see if it helps
void receive(const MyMessage &message) { if (message.type == V_STATUS) { switch (message.sensor) { case CHILD_ID: state = message.getBool(); // Change relay state setRelayState(RELAY_PIN, state); saveState(CHILD_ID, state); // Store state in eeprom // Write some debug info printStateChangedDebug(CHANGE_STATE_SOURCE_RADIO, CHILD_ID, state); break; case CHILD_ID_2: state2 = message.getBool(); setRelayState(RELAY_PIN_2, state2); saveState(CHILD_ID_2, state2); // Store state in eeprom // Write some debug info printStateChangedDebug(CHANGE_STATE_SOURCE_RADIO, CHILD_ID_2, state2); break; } } }You might also like to move the the lines that set oldvalue to new value. They probably should be inside the relevant if statement. In the original relay with button actuator code they are outside but that is using push buttons not toggle switches.
if (value != oldValue) { send(msg.set(state ? false : true), true); // Send new state and request ack back // Write some debug info printStateChangedDebug(CHANGE_STATE_SOURCE_SWITCH, CHILD_ID, value); oldValue = value; } if (value2 != oldValue2) { send(msg2.set(state2 ? false : true), true); // Send new state and request ack back // Write some debug info printStateChangedDebug(CHANGE_STATE_SOURCE_SWITCH, CHILD_ID_2, value2); oldValue2 = value2; }The other thing you should note is that as the code relies on an ack from your gateway to switch the relay your hardware switches will not work if the gateway is not available. You will need to further modify the code to ensure the switches work at all times.
