It is still silent. Between 13:00 and 17:00 I got zero messages from the electicity/power meter.
I got plenty Water and Heat -type. None recognized. So won’t be able to decode. Same vendor.
I used ESP32 (back alive), and also HA terminal with wmbusmeters and RTL-SDR blue dongle connected (dusty, 5-10 years in drawer… :D). I am receiving similar count of recognized messages.
Anyway — I wrote to STOEN Operator, to person that gave me keys, asking few questions. He only confirmed the frequency. 868.950MHz. If I don’t get anything from the meter in next 2 days, I will raise a ticket to STOEN asking for a support there. I saw somewhere that someone had same problem and was resolved by technician uploading newest firmware. After that meter started sending messages.
BTW. My issue with getting no messages was caused by … no CPU time. Problem re-appeared when I was adding web, mqtt, or status sensors (like uptime), or even logging=verbose. I was observing degradation in “received” messages, to the point that there were only “3of6” issues.
ESP32 can be used only if there is really no other component competing for CPU.
I would say that likely to be due to the decryption functionality of the code. I think that used to be an issue with P1 devices where DLMS has to be decoded, so it was usually outsourced to the main system and telegram were just transmitted then.
So, what was your sweet spot regarding additional componenets for getting all the messages through?
I would add a comment to the aformentioned discussion regarding the no CPU time, it might be useful for other people as well.
If it has WMBUS then yes, you should be able to read it. The ELGAMA website suggests it can be deployed with wireless MBus.
By the way, can anybody comment on this from the PGE website:
wystąpienie z wnioskiem o umożliwienie komunikacji licznika zdalnego odczytu z urządzeniami odbiorcy oraz zapewnienia dostępu odbiorcy do danych niezatwierdzonych dotyczących zużycia w czasie zbliżonym do rzeczywistego.
I am quite curious what do they meant by the word niezatwierdzonych here.
But unbalanced is not the same as niezatwierdzonych. And what about those who hasn’t got photovoltaic generation? For them it should be zatwierdzonych… Right?
That word indicates that the meter’s reading is not verified, but what verification does it need as the meter should be certified measuring device.
OBIS 1.8.0 energii czynnej efektywnie zużyto do sieci
Or does it indicate some further calculations regarding reactive, inductive and capacitive energy further on?
