IR Node resending last signal ca every 15 minutes

[kiesel]

@electrik

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

@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?

@kiesel getting a log of the serial output might be the quickest wayto troubleshoot. you already have nice serial prints that will describe what the node is doing.

@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!

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:

Appdaemon log:

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]

@kiesel Nice work. I am not familiar with Home Assistant but I can move this entire thread into the Home Assistant category if you want.

[kiesel]

@mfalkvidd

That would be great, thanks!

[mfalkvidd]

@kiesel done!

[kiesel]

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?

[olka]

@kiesel Have you tried to replace the sensor with a pull-up resistor?

[kiesel]

@olka

Sorry for the late reply, I have been busy with a few other sensors.

Do you mean attach a pull-up resistor to the ir sensor? I haven't tried that, but from what I can see the problem isn't the sensor node, it's the integration that sends events when no event has been sent. The gateway log doesn't show a new message being received so I guess the node isn't to blame.

[electrik]

Is the update mechanism maybe triggered by another meessage coming from your node? e.g. temperature or battery update

[kiesel]

@electrik

These updates trigger the event:

{"log":"2020-03-11 12:42:01 DEBUG (MainThread) [homeassistant.components.mysensors.gateway] Node update: n
ode 3 child 255\n","stream":"stderr","time":"2020-03-11T11:42:01.635196016Z"}

From what I can see these updates happen whether I trigger something on the node or not, unfortunately.

[electrik]

Those are battery reports. You should have a look at the update mechanism in appdaemon, maybe that is also responding on this event.

Can you post the code of that? I don't have experience with it but interested if this can be useful for me also, instead of node-red for my automations.

[kiesel]

@electrik

Thanks, I'll have a look at those updates.

Do you mean the code I am using for my appdaemon app? I got everything I use from here: https://github.com/eifinger/appdaemon-scripts

This is much cleaner and easier to understand than my code, but let me know if you want it anyway :)
