Guess what… EON most likely opened Elna! I’m getting 3 entities! So far I’ve checked out Power flow.

You are in luck!
I got the Pure Energy meter and Error message regarding communication! Did you do anything special during the configuration?
Nothing special. Installed, tried, uninstalled several times
Than gave up. Today it apparently started working by itself in the afternoon.
For sure device update. It has API accessible now. When you open the device IP in browser, you get this:
{“id”:“xxxx:xxxx:xxxx:xxxx”,“mf”:“NET2GRID”,“model”:“SBWF4602”,“fw”:“1.7.14”,“hw”:1,“batch”:“HMX-P1D-XXXXXX”}
(I’ve removed identifying ID and batch number).
So if we can get hands on the API spec, we can get much more data I guess.
For now I get entities with current consumption, total usage (lifetime??) and current production.
The browser shows nothing when I connect to the IP address.
Here you can read about the Pure Energie meter and these values
description is that the device leaves the following values and it matches what you describe.
Power Flow (W)
Energy Consumption (kWh)
Energy Production (kWh)
My device has software version 7.14 in EON app.
I have model SBWF4602 and version 7.2 in the app
Do you have good WiFi signal? I’m thinking it maybe did update in my case after it thought the WiFi is strong enough fo software update. I had shitty signal, my meter sits on the pole quite far from the house, so the connection was just enough to connect about 50% time. I have small shed close by, so I’ve stuck powerline wifi access point to it and now it has perfect stable connection. Otherwise I don’t know. I wonder if 7.2 is lower version than 7.14, or the opposite.
ver 7.2 is higher than ver 7.14. Haven’t found in the app how it works with software updates, assuming that you can’t control this yourself unfortunately.
Wifi coverage is perfectly ok, here is a screenshot from the app
Here screenshot from app
Mine started working when I pulled the dongle and reconnected it while reloading the pure energie integration.
I forgot to respond here earlier, but mine also seemed topp have automatically started to be friends with HA around the same time as others mentioned above. I didn’t touch anything at all, so either an auto firmware update or an explicit unlock from the Eon side.
För the recorded: I was in contact with their support asking whether I could access the data, but never got any proper response.
Those of you who got it working, what software version and model do you have? I have 7.2 and SBWF4602 and here it not working
This is what works for me:
SBWF4602 by NET2GRID
Firmware: 1.7.14
Mime also started to work, I tried a bit before bot to no luck. I was surprised to see that it now works 
Connected my Elna today, delivered with version 7.2 and does not work. Did yours get updated automatically yet?
Yes, last week it all of sudden appeared in HA. version 7.14 now (which I believe is higher than 7.2. It is not 7.1.4, ie 14 is bigger than 2.
A question in Swedish, don’t think it matters since this is for E.ON Sweden only.
Vet någon om man kan se hur fördelningen ser ut per fas? Så att man kan se om man har en snedfördelning på faserna?
Oh great to hear. Hopefully mine will get updated as well soon. Yes I believe so as well 7.14 should be 12 versions higher than 7.2 
From what I read, the “Pure Energie” integration now works with more products from NET2GRID. As a developer of the integration, I’m curious about which brand, model and firmware version are working well (for documentation in HA) and who is still experiencing problems.
