MySensor on Hass.io - can't get it work

[MaTy]

@martinhjelmare
You mean in my sketch, something like this?

void receive(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_LIGHT) {
     // Change relay state
     digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
     // Store state in eeprom
     saveState(message.sensor, message.getBool());
     // Write some debug info
     Serial.print("Incoming change for sensor:");
     Serial.print(message.sensor);
     Serial.print(", New status: ");
     Serial.println(message.getBool());

I had optimistic set false.

BTW: Strange thing, baud rate in my sketch is 38400, but when I set it up in Hass.io, lights won't work, when I changed to 115200 in .yaml (in sketch is still 38400), all works fine, except the states update.

@maty

In your example above you never send the feedback from receive. Use the send method
from within receive to do that.

In what sketch have you set baud rate to 38400? For the light device or for the gateway? It's only the gateway baud rate that is relevant for home assistant config, since it's the gateway that interfaces via the serial connection to home assistant.

@martinhjelmare

Should it be something like this added to my sketch?

send(msg.set(RELAY_1;V_LIGHT)
send(msg.set(RELAY_2;V_LIGHT)
...

I ment BAUD_RATE defined in this sketch

#if F_CPU == 8000000L
#define MY_BAUD_RATE 38400
#endif

Once again, sorry for tons of noob questions. But I didn't write that sketch by myself, and my knowledge about programming is below basic.

[martinhjelmare]

Something like this:

send(msg.set(state));

The arduino mega runs at 16 MHz so that if block won't be entered, and the define of baud rate won't change.

Hi,
I checked my sketch once again, and confronted it with MySensors documentation, and I actually found the send message command in it. Should I change something to make it work properly with Hass.io

void loop() {
  // Send locally attached sensor data here
  if (debouncer.update()) {
    // Get the update value.
    int value = debouncer.read();
    // Send in the new value.
    if(value == LOW){
         saveState(1, !loadState(1));
         digitalWrite(RELAY_1, loadState(1)?RELAY_ON:RELAY_OFF);
         send(msg.set(loadState(1)));

@maty

Yes. There are two ways of interacting with the device to make a state change. Either by pressing the button or by sending a message from home assistant to the device. The send command you showed above will only happen if the button is pressed when the loop is running.

When you send a message from home assistant to the device, to change the state, the message will be received in your sketch by the receive function.

So you need to add a send command to the receive function and send the new state back to home assistant after doing the digitalWrite call and saving the state.

@maty Yes serial gateway hooked to the pi

[Rincewind]

@tom-carpenter How did you configure the serial gateway in configuration.yaml? can you please post that section?

Also what arduino hardware did you use?

Thanks
