Did you read the attributes of the 0x0702 and 0x0b04 clusters? The 0x0b04 seems to show only default values. The 0x0702 suggests you’re currently consuming 8.3 kW. Can you relate this to what the meter is displaying? Life-time consumption is again the default value.

[Jopinder]

Yes, all values are after clicking "read" and the meter shows ~1-1.2kW atm. To open the HAN-port on Norwegian meters we have to ask the power company to do it, and it says on "My pages" that the port is open. So I'm not sure why it shows default values.

I will request a close and re-opening of the port to see if that helps with the values.

Thank you, @Jopinder, for requesting support for the Develco EMI Norwegian HAN. I have one myself, but have not been able to add it to my Conbee II USB adapter, hence I am not able to get any readings into my HomeAssistant server. I have asked my power provider (LOS) to open my HAN port, and they confirmed that they had enabled my HAN port. Even so, I am not able to see my Develco sensor in ConBee II. I tried using the PhosCon web interface as well as the VNC GUI.

Can you tell me (details) how you managed to bind your Develco HAN to your Deconz adapter?

Thanks in advance and Happy New Year.

[Jopinder]

My power company has confirmed the HAN port is opened after some mailing with their support. I'm going to contact the seller over new year (Wattle/Home Control AS) to ask if they have done anything to the firmware as they claim it only works with their gateway.

@gantonjo-tnm I tried to add it via the web-gui and Sensors -> Add new sensor and chose "Other", but it did not show up. I then reset the Develco and added it again via the web ui. It still didn't show up in the web ui, but this time in the VNC UI as connected (but unable to get any readings from the power meter). So nothing special I did I'm afraid.

Btw, I have Skagerak Energi and the Aidon meter, which meter does LOS use?

[gantonjo-tnm]

@Jopinder LOS uses Kamstrup meters.

I have the same reader, but my Manufacturer Code comes up as 0x117c as opposed to 0x1015. Very strange, this seems to be the code for IKEA? The sensor is not talking directly to my hub, it's only within range of one of my IKEA bulbs.

My reader is bought from Elektroimportøren, and the web shop lists it as compatible with "Homely": https://www.elektroimportoren.no/emi-norsk-han/4514731/Product.html?Event=livesearch

My meter is also from Aidon. I've gotten a confirmation from my power company that my HAN port is enabled.

@gantonjo-tnm I had to upgrade to the latest deCONZ beta before I was able to get cluster information etc. from my HAN sensor. Got it from here: http://deconz.dresden-elektronik.de/raspbian/beta/

Here are my screenshots:

I just realized that the meter is already turning up in Home-Assistant, probably because I'm on the current deCONZ beta?

But alas, it's not showing anything useful yet (the second screenshot is particularly hilarious)

[gantonjo-tnm]

@einarjh: Very interesting. Thanks for the information, allthough I am not sure how to upgrade my Conbee II to the latest Beta version. I am running my Home Assistant in Docker on an old Apple Mac Mini 2.5 that is running Ubuntu 18.04.3 LTS. Deconz is running as Docker image "marthoc/deconz".

[einarjh]

Derp! I just started reading the documentation for EMIZB-132 a bit closer, and found this:

Seems there is an extra step needed to enable metering data from Aidon meters, which both @Jopinder and I have.

[ebaauw]

Best define these attributes in general.xml and set them thru the deCONZ GUI. You would need to know the type of each attribute.

[gantonjo-tnm]

@einarjh Ok, I managed to update my Docker image to latest "marthoc/deconz", but even so I am not able to find my Develco EMI Norwegian HAN adapter. I have tried to factory reset it and unplugging it after the reset. No luck binding it to my ConBee II :-(

(Since I used docker-compose, "docker-compose down && docker-compose pull && docker-compose up -d" gave me the latest version of the "marthoc/deconz" Docker image):

I messed around with this some more tonight, but can't quite get it to work.

As far as I can tell from the manufacturer documentation, the manufacture specific attribute ID 0x0302 needs to be added within the 0x0702 cluster, with the manufacturer code set to 0x1015, so I tried adding it like this (with an educated guess for the type, since this is omitted from the documentation):

<attribute-set id="0x0300" description="Develco Specific" mfcode="0x1015">
  <attribute id="0x0302" name="Interface Mode" type="enum16" access="rw" default="0x0200" showas="hex" required="m" mfcode="0x1015">
    <value value="0x0200" name="Norwegian HAN"></value>
    <value value="0x0201" name="Norwegian HAN - Enable extra load. This is need to enable Adion meter communication"></value>
    <value value="0x0202" name="Norwegian HAN - Aidon Meter supporting Norwegian HAN HW interface"></value>
    <value value="0x0203" name="Norwegian HAN - Kaifa meter and Kamstrup meters running old firmware"></value>
  </attribute>
</attribute-set>

That didn't turn up at all, but when I used the IKEA mfcode, it showed up. Why is my Develco device cloning the manufacturer code for IKEA?

Next problem: the attribute id 0x0302 seems to be conflicting with the attribute id for divisor, when I double click on my new attribute, it brings up the widget for divisor, ref. screenshot:

If I give a fictional, unused attribute set ID, it shows the expected widget with a dropdown, but that won't let me read or write, of course. I get UNSUP_MANUF_GENERAL_COMMAND …
