I had a look at the Home Assistant logs and I think I have been blaming the wrong beast, my code seems to be innocent.

I use appdaemon to execute actions in/from Home Assistant. There I can see exactly when a "ghost"-update was received.

Matching those timestamps with timestamps from the Home Assistant log was spot on:

Does anybody have an idea how I can prevent these updates? Or should I continue this thread in the Home Assistant forum of mysensors?

@mfalkvidd @phildefer

I can confirm that the code compiles and runs on my rasbperry pi 4 model b. I am using a rfm69 radio and that seems to be working too. I couldn't test it yet though since I haven't wired any rfm69 nodes up yet.

@mfalkvidd

Good catch, I didn't do that. Before I saw your message I checked the wiring and I introduced a new bug apparently because now the MQTT-gateway doesn't start anymore either, so I'll have to rewire.

I'll write again after I did that. Thanks for the help!

@mfalkvidd

I am a bit embarrassed that I didn't post them straight away. I'll collect a bit of data during the night and send the logs tomorrow. Thanks!

@sundberg84 I did, thanks, I discovered ISRs. Thanks for the support.

@mfalkvidd

I am planning on using a booster, so that's very good to know, thanks!

So this was either a faulty module or bad soldering. I soldered a new module and now everything works as expected. Thanks for the help!

@electrik perfect, thank you both!

I think this was solved by soldering a wire to the reset pin of the rfm69 and pin 29 of the raspberry pi and reconfiguring the gateway with

--extra-cxxflags="-DMY_RFM69_RST_PIN=29"

Now the connection is instant (before it was about 10-20 seconds IF it worked at all.

But since this is my first gig with electronics it might just be that I had a bad connection and moving the wires around fixed it....

@ricmail85 sorry for the late reply. I soldered it to a free pin on the pi and reconfigured the gateway.

Use this as part of your configure

--extra-cxxflags="-DMY_RFM69_RST_PIN=29"

If you connected to pi pin 29.

I am working around the issue by sending a zero after every received ir_value, that way I can identify refreshes in home assistant/appdaemon

send(msgIrRecord.set(ir_value));
send(msgIrRecord.set(0));

This is a very ugly workaround though, does anybody have areal fix?

@mfalkvidd

That would be great, thanks!

So it seems that every time a Node update was triggered Home Assistant was told that there was a new value received from the IR-sensor.

Here is the whole log from Home Assistant:

Does anybody have an idea how I can prevent these updates? Or should I continue this thread in the Home Assistant forum of mysensors?

@mfalkvidd

I am a bit embarrassed that I didn't post them straight away. I'll collect a bit of data during the night and send the logs tomorrow. Thanks!

@skywatch

I want to put the node to sleep. And it actually works very well, when it is woken up by a pin interrupt it reads the data and sends them to my serial gateway.

The issue is that it repeats messages.

I have now covered the sensor and I still get messages ca every 15 minutes.

Is resending messages a part of the send()-function maybe?

@electrik

I am using a serial gateway, but long term plan is to use an mqtt gateway.

Hi,

I attached a TSOP 38238 to my arduino pro mini (3v) wit the goal of relaying IR signals to my controller (Home Assistant). On the face of it everything works: When I press a button on my tv remote a message is sent. But: about every 15 minutes the node resends the last IR command it has seen.

Also attached to the node is a lux sensor and a temp/humidity sensor that are pulled every 90 seconds (I don't need updated temp/hum/lux values every time somebody presses a button on the remote).

The IR sensor is attached to pin 3 and wakes the sensor up every time there is new data. When the ardunio is woken up it checks whether it was by interrupt or by time an then checks the corresponding sensor.

Can anybody see what I am doing wrong here? Here is a pic of the sensor in Home Assistant:


This is from last night, all lights are off and nobody used the remote. I can't find a reason why the node wakes up ~ every 15 minutes.

Does anybody have an idea or a workaround?

I didn't know that delay blocked, good to know, thanks. I have nothing that's supposed to run in the background so delay works for the time being

Congrats on the node! Is the code available somewhere? I'd like to take a look. Always good to learn new stuff.

I think this is solved: It appears that the interrupt wakes the arduino who then queries the sensor before the full code is received. I added a

delay(100); 

to give it a bit more time to read the data.

void ir_received(){
  delay(100);
    if (irrecv.decode(&ircode)) {
      //#ifdef MY_OWN_DEBUG
      //dump(&ircode);
      //#endif
      unsigned long ir_value = ircode.value;
      if (ir_value == REPEAT) //if repeat-code: send last code
      {
         ir_value = last_value;
      }
      else{ //if not: save new value as last value
        last_value = ir_value;
      }
      Serial.println(ir_value,HEX);
      
      send(msgIrRecord.set(ir_value));
      
    }
    //delay(100);
    irrecv.resume(); // Receive the next value

    Serial.println("IR Processing done--------------------");
}

If anybody has a better idea please let me know.

@skywatch

I used the sketch "IRrecvDump" from the IRremote library to verify that only one code is sent per button press, so I don't think that's the problem.

With that sketch the same code is written to the serial monitor every time I press the same button.

The issue is that code uses polling and I want the arduino to sleep because it is a battery powered node.

/edit: irrecv.enableIRIn(); didn't make a difference unfortunately.
