AM550 config for Slovenia (encrypted)

[davidg-0]

Hi,
I'm using WT32-ETH01 via Ethernet, specifically this board (https://github.com/zuidwijk/slimmelezer-wt32-eth01)
Meter: Iskraemeco AM550 with P1 port (AM550-TD1.21)
Country: Slovenia
Communication is encrypted+authenticated.

The board powers up via P1 port, but there are no readings showing.
I'm not sure if I've put wrong settings, or is this combination of meter/country not supported by AMS yet.

Could you please help me troubleshoot this setup?

Slovenia is currently rolling out dynamic - block based power pricing, so I'm sure I'm not the only one trying make this setup work.

Appreciate your work!

Try a Telnet debug to see if there is any data coming from the meter: https://www.amsleser.no/module/ets_blog/blog?id_post=24

I'm sorry. There's still no "Debugging" tile.
I do see a new "HAN: Parse error", when using WiFi though. Does that help to indicate anything?

Joining this thread as I'm also from Slovenia (I assume I have the same meter model as @davidg-0) and also have problems reading my Iskraemeco AM550 energy meter.

I recently received POW-P1 (great device, btw!) but only today managed to get my energy distributor to enable unencrypted P1 port on the energy meter. I have POW-P1 configured at 38400/8N1.

It can read incoming frames but seemingly not all of them (no errors in the logs though).

The dashboard only shows meter type (Iskra) and (summary?) consumption (next to the Iskra label). HAN indicator is colored red. There are no parse (or other) errors shown.

What it doesn't show is current/past input and/or power consumption.

Based on the debugs it's receiving HDLC/LLC/DLMS frames every second.

This is an example DLMS frame:

        <UInt32 Value="00000000" />
      </Structure>
    </DataValue>
  </NotificationBody>
</DataNotification>

after this frame I get this in the logs:

(D) Received valid DLMS at 30

(V) DLMS

One more thing, the following warning is dumped to the logs every 30 seconds:

(W) No HAN data received last 30s, single blink

Not sure if any of the above helps.

I too would really like to see this working.

If I can be of any additional help (debugs & such) please let me know.

just realized there's a discussion on reading Slovenian power meters in ticket #869, will follow there

[ArnieO]

Yes, please use that other thread. Slovenia is difficult - for the reasons explained there.
We will need information similar to what has been provided from some users in #615 to handle the different types of Slovenian payloads.

I think I managed to make it work.
My grid company is "Elektro Ljubljana".

I had wrong baud rate set, since I referenced Wiki/Known hardware configurations
I found the correct values for Slovenia (38400/8N1/512/non inverted) here:
#869 (comment)

Thanks again for the open firmware, and kindness to help with non standard configs!

[ArnieO]

Thank you for the good news! Yes, Slovenia seems to use 38400 baud.
I have added a separate line in the table now - for Slovenia. https://github.com/UtilitechAS/amsreader-firmware/wiki/Known-hardware-configurations
