Hi!
I live in Finland and I have Echelon 83332 meter. Seems that I'm receiving push messages from the device's optical port (ttyUSB0).
However I have no idea how to parse those messages. I'm looking for a way to read real-time energy consumption.
Any help would be highly appreciated. Is decryption key required in Finland? Operator is Caruna.
Hi,
Hi,
If you add a received push message as a hex string so I can check if the push message is sent as DLMS and what are the settings.

Hi Mikko,
Hi Mikko,
Thanks for such a quick reply!
Here's the output from Push Listener Example.
Push messages are sent/received every five seconds and split to two rows.

Hi,
Hi,
This doesn't look like any protocol that I know. I believe that your serial port settings are different than the meter uses.
Try to start the app with
python main.py -s /dev/ttyUSB0:B8:14400
OR
python main.py -s /dev/ttyUSB0:B8:19200
OR
python main.py -s /dev/ttyUSB0:B8:38400
OR
python main.py -s /dev/ttyUSB0:B8:56000
OR
python main.py -s /dev/ttyUSB0:B8:57600
The app is using different baud rates. You should see a message that starts with 7E. Your serial port settings are correct when you see that.
BR,
Mikko
Many thanks for helping me
Many thanks for helping me out!
So far no luck with any of the mentioned serial port settings.
I also tried (and failed) Gurux.DLMS.Client.Example.python with the following output.
Maybe Finnish meters cannot be read?
```
$ python main.py -t Verbose -S /dev/ttyUSB0

Hi,
Hi,
If the meter sends push messages you don't establish the connection for the meter or read anything. You just wait for the data the meter sends.
I found 3 pcs of Echelon 83332 meters from the shelf. They are older and they don't send push messages and they don't use DLMS. I sent an email to Echelon and asked if the new firmware can be send so this can be tested.
A reply is usually coming in a few days. I'll inform you as soon as I have more information about this.
BR,
Mikko
Thanks again. Amazing effort!
Thanks again. Amazing effort!
Just to let you know the exact model is Echelon 83332-3IHAH.
I contacted Caruna, my energy distribution company, and they were quite strict that optical port cannot be used by end customer. ¯\_(ツ)_/¯
