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:

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?

Seems you where both right. A short drained the battery (which I didn't notice) and getting rid of the short and using a new set of rechargeables solved the problem.

Thank you very much!

@KevinT

Thank you for your feedback!

I have (or at least I think) a decoupling cap on the pcb (C2). And you are right, I should have added the schematics from the start.

I tried doing it on openhardware.io but now the pics of the pcb itself show an older version (the schematics are fine though, I'll add them here too).

I added pins for a HDC1080 temperature/humidity sensor, because that's what I'll probably end up adding anway.

1 interrupt should be all that I need, but if I need more I'll probably use this workaround. But thank you for letting me know about the micro, didn't even know that existed

@skywatch That's pretty sad to hear.... it's what got me into electronics/soldering. Are there any comparable projects that are seeing development?

@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!

@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!

@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!

@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.

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!

@skywatch That's pretty sad to hear.... it's what got me into electronics/soldering. Are there any comparable projects that are seeing development?

Basically the title. According to github nothing has been merged to master in the last 5 years. Can anybody speak to the stability of development?

I have three nodes running 2.4 alpha (created those in 2019, needed to use dev because of some rfm69 issues irrc), and my gateway recently died. I am creating a new gateway and I am wondering what the best course of action would be.

Thanks!

Hi,

I am looking into buying a minimalist rfm69hw shields for wemos d1 mini.

I found this fantastic project, but it costs 25 usd and its 10 pcbs.

https://www.openhardware.io/view/392/Minimalist-RFM69HW-Shield-for-Wemos-D1-Mini#tabs-comments

Assuming that not everybody here used their 10 pcbs: Is anyone willing to send one or two to Germany? Not for free, of course!

Thanks!

Thanks, I'll keep this in mind if I decide to debug it. I realized that I am also tired of patching the gateway through to the doctor container inside an LXC so now I am looking at creating an esp gateway.

Just need to check if I can find a pcb on here.

Thanks again!

Hi,

I have been using my gateway (arduino pro mini/rfm69) for a few years now, but it suddenly stopped working, or at the very least home assistant can't read the output anymore. I am getting this:

2024-09-18 22:28:07.973 WARNING (MainThread) [mysensors.message] Error decoding message from gateway, bad data received: 0;255;3;0;9;0 MCO:BGN:INIT GW,CP=RPNGA---,FQ=8,REL=0,VER=2.4.0-alpha
2024-09-18 22:28:07.973 WARNING (MainThread) [mysensors] Not a valid message: invalid literal for int() with base 10: '\x00\x000'

I am not sure why this is. A recent home assistant update? I touched the gateway and some of the connections came lose? Did the gateway just partially die?

If anybody has troubleshooting tips for me I'd be very happy!

Thanks!!

@KevinT

hmmm, that's really not the case atm. I just ordered the first batch and will report back once I assembled the first sensor. If it's an issue I'll rearrange the footprints. Thanks for the info!

@KevinT

Thank you for your feedback!

Hi,

How do you attach/place your sensor boxes close to the door in a way that is visually appealing but also doesn't make it too hard to get to the sensor for code and battery changes?

I thought about Tesa Power Strips but maybe there are better solutions out there?

Hi,

To increase the WAF of my door/window sensors I created this small PCB. It connects a RFM69 to an Arduino Pro Mini with the lowest footprint I could come up with. There is additional space for a booster and a voltage divider though the voltage divider is optional (Just cut it if you don't need it).

Criticism/Feedback and everything in between is very much welcome since I literally have no idea what I am doing and I hope somebody can point out issues before I order my first batch. So: so far this is untested, please don't order it until I got my hands on the first batch.

I was also hoping that somebody could tell me how to set up the project so that mysensors gets a few dollars for every ordered batch, I've seen other projects do that and I want to give back to the community too.

If, unexpectedly, there are no issues with the PCB the next step in the project will be to create a 3D-printable enclosure (I am leaning towards tinkercad, but again, I have no idea what I am doing and I am open to suggestions).

Small pro mini rfm69 shield

Does anybody have a link to a fixed version of this board? It's exactly what I am looking for form-wise, but I'd be nice if VCC was wired to 3.3v out of the box. Thanks!!
