Enabling the Homey Energy Dongle’s Local API
Using the Local API
The Homey Energy Dongle’s Local API is a WebSocket that can connect to any WebSocket-capable client. Once connected, the WebSocket will output the raw data received from the smart meter.
You can find an example on GitHub of how to connect to the Homey Energy Dongle’s Local API and parse the data from the smart meter.
Is there a plan to make the real-time data (like import/export power) from the energy dongle directly available using the Homey App SDK? It would make sense to have this data centrally available on the Homey Bridge / Pro itself so that more than 2 apps can have access and not every app needs to communicate with the dongle.

I don’t have a Homey P1 device to compare with.
The Homewizard sends these values to Homey:
The “current usage” value is refreshed every 10s, and is the sum of your consumption minus your generation from solar panels/battery/windmill etc.
Gas is refreshed every 5 mins.

Most Homey users already have a (HomeWizard) P1. Does it make sense to replace it with the Homey Energy Dongle or in my case add it to a P1 splitter because the HomeWizard P1 is required for the HomeWizard Plug-in Battery.
In my humble opinion you don’t need the Homey P1 dongle when you already have a Homewizard P1 dongle
No need for that.
The Homey P1 dongle has a “thru” connector, to connect another P1 dongle, like needed for, for instance Zonneplan’s own P1 dongle (NL).
Hi Peter, i do have one myself.
maybe I stated the question incorrect, what is the benefit of upgrading to a Homey dongle

The Homey Energy Dongle is now available
For the Homey Energy Dongel:
All values are refreshed every 1s with te info you smart meter transmits
and here are the screenshots for me ( Landis+Gyr E360 - 3 Fase - With Gas Meter, no Water meter connected)!

Hi all,
I’m looking into buying the new Energy Dongle. My issue is that I live in an apartment on 3rd floor and the power meter are in the basement of the building. Therefore, the dongle would not be able to connect to the same wifi as the Homey Pro.
We do have another wifi in the basement thought. So my question is: Would I be able to connect the Energy Dongle to my Homey Pro when they are on 2 different networks?
Thanks! 
Possibly only when you own both wifi networks, as part of your LAN, and both wifi devices are configured to use the same subnet, like 192.168.1.x

Got it today! A lot of problems.
First install honey crashed
Had to do a reset which is not in the manual
Now it says it cannot read my smart meter which is weird its a Landis Gyr+ E350 SMR 5.0
Led is blinking white
Tried it with power without usb power
Reset it multiple times
Diagnostics F4EDAE49
I hope athom will reply soon otherwise i will return it
That’s quite annoying because it all went by itself here. I did miss the information in the manual on how to install it. But suddenly a pop-up appeared that the dongle was connected and whether I wanted to install it.
I did this, then had to enter wifi information and then it immediately performed an update. In a few seconds the dongle was online in my Homey. Oh yes, I still had to indicate how many phases I was using (it didn’t take that over from my P1 meter). But it works fine, I’m satisfied.
Annoying that it can also go differently, maybe someone from Homey can help you with that. Otherwise try again, with only the Dongle on the P1 meter? (if you hadn’t done that already of course).
Hi all,
Just got my dongle in (finally). Plugged it in. Red light. Gave it juice through usbc and I got a breathing blue light. But the app doesn’t see it. I have resetted the dongle. Still no pop-up of the dongle.
Bluetooth for homey app is on. Anyone has any idea how to connect it? I’m very mad that I can’t call athom themselves and a ticket will take 1-2 WEEKS. So I’m asking here first.
Kind regards,
Michiel.

Have you tried going to add device and wait for a bit?
Ok had some struggles as well, at first breathing blue led, tried connecting using the app > add device > and waiting > refused the wifi pass, then was blinking red. Not sure if that meant not getting enough power. Tried resetting (which should really be in the brief manual). That did not seem to change anything for me. So then made it so there was a power source and it turned purple for a short while (still not sure what that meant). Tried resetting again… finally blue light, reconnected as before … now working.for roughly an hour.
