Best way to connect Smart Meter P1 with Homey

Hi,
I have searched the forum already, but i was wondering what kind of device will be best suitable to read the Smart Energy meter counters. The Dutch Smart Meter has a P1 connection. What kind of device or way is the supported or advised way to read this meter?
And second, if you have a KwH meter with S0 bus, is there any way this is supported?
Kind regards
Martin

maybe this could help?

Or else you could try to connect a arduino to the P1 port and let Homey poll the Arduino for data or push the data to homey.
Here I use 2 arduino's that push data from;
Kamstrup Multical 602 to my RaspberryPi with Sqlite database
Kamstrup 162 to my RaspberryPi with Sqlite database
The raspberry uses WebSolarLog to monitor the P1 and solarpanels.
There is Toon, HomeWizard's EnergyLink or https://www.plugwise.nl/slimme-meter-uitlezen for the lazy people, but I can recommend to use a raspberry pi with https://www.sossolutions.nl/slimme-meter-kabel instead as it is much more fun and reasonably well documented.
I use the P1-ETH Converter Module P1-ETH V4 Converter Module from http://www.smartmeterdashboard.nl/webshop and have my home server write all values to a mysql database. I'm hoping that one day someone makes a plugin for homey to get data from a mysql database (or i might script some myself).
In any case i think you will need something that connects the smartmeter to the network since you don't want to place your beautiful new homey in a fuse-closet.
Just curious, why would you want Homey connected to your smart meter? I can see the value of an app that is possible to read data from a database that has the energy data but as mentioned already since you can then query Homey for statistics, but you would be better off with something else as a datalogger then your Homey like a RPi.
I personally use my Synology NAS to push data from my smart meter (with serial to USB cable) and my solar panels ( SBFspot connected to speedwire of my SMA inverter) to PVOutput.org. If you own a NAS which already sits in the fuse closet this might be an option as well.
One of the most compelling use cases for home automation has been saving on energy. There have been numerous projects which have demonstrated that providing real-time and meaningful insight in a household's energy use can have a significant impact on the energy bill. Numbers like 20% savings or more are not uncommon.
The homey would be a perfect device to realize this. It has a led-ring which can show the current use compared to a household's average or target. Homey lends itself to be positioned on a prominent place in the living room which will serve as a constant reminder to save energy.
Secondly, the ability to develop innovative apps together is another very nice feature. I definitely want Homey to know my energy history so apps do fancy visualizations and data analysis.
Energy monitoring isn't the most obvious use of Homey, but I think it should be a primary function of any modern home automation platform.
Nice @JaapPelt +1
Is there any news about supporting a system like plugwise or something?
I just got the EON system.
It uses a fifthplay box, which has an api available when you google.
It uses bricks to build its connections, there are a lot available, but I got 2 meters for traditional meters and a P1 cable.
And the system is for free when you transfer, also comes with 2 smart wall plugs.
Although i think Toon is a nicer system but also a lot more expensive and less compatible.

Hi there,
I use a raspberry P1 to connect with a P1-usb kabel to the "slimmemeter" . Domoticz reads the data.
I hope that i can use the Homey to read the data via wifi.
Maybee any thought here ?
greets
I have a Qnap nas but can't find a app for it,
So I was thinking on a Raspberry p1 as well, but i don't know of there is any support for Homey.
I wrote a plugin for pimatic, which runs on a RPi. It should be very easy to write some code which runs on an RPi and sends the received P1 "slimme meter" data to Homey.
But I'm very new to Homey and development for the platform. The api looks ok. Homey itself is promising.
I'm looking into the Plugwise Smile P1 and the Enelogic P1 to read data from my smart meter, since @gruijter_dev has written apps for both. I'm just wondering if someone could tell me the difference between the two (if there is any), as the Plugwise is more expensive and I don't really see any added value when comparing the apps for both.
Cheers!
App for Homey by @gruijter_dev has plenty of possibilities to monitor your energy consumption. Would be nice to have some example Flows though .
I have a Plugwise Stretch too, to monitor my solarpanels that are connected to a Growatt inverter. I didn't find a way to read these Growatt/Plugwise data with a Homey-Plugwise-App.
