For a weeks i am starting to implement all smart products with openhab. and i would really like to add a new feature to my openhab instance: Energy monitoring.
I am living in the netherlands(Europe) and i looking for the best option to add energy monitoring to my setup. I have some experience with programming, but i do love out of the box solutions that works easily with a openhab binding.
What do i want?
Intergration with Openhab offcourse
Easy setup or some setup with Raspbarri pi
Next to the smart energy i have a nighthawk router with usb ports can i do something with that? p1 to usb? or isn’t that going to work at all?
Live also in NL and I am using Dsmr reader.
You can connect it via different ways to openhab, but until now did now saw the time/need to do it.
It give decent interface and insight in your power usage.
I am running on a Raspberry PI 4b 4GB installed Openhabian it is running perfectly continuously for 202 days now.
Have a connection to my Smart Meter (DSMR) with a P1 to USB cable.
Store the data in a MYSQL database and make it visible with Grafana
It’s running on a Raspberry pi 3B, together with openhab. Both are running fine on the raspberry. Also with a P1 usb cable connected, which I bought on ali.
And one of the future idea’s is to use Grafana for more visualization, also because I do have solar panels. I installed a seperate modbus meter in the electricity box, but also didn’t found time to connect that one either. First a RPi4 I guess, since openhab and grafana on the RPI3 gave me issues with RAM.
I gues you could use a RPI and run an application on it that can relay the incomming dsmr data to your server. Asuming you’ve got a way to get a networkconnection in your meterkast, and you can use that connection to hook your RPI up to your network, I can think of a couple of options:
Install openHAB on the meterkast RPI and use the MQTT event bus option to relay the dsmr data to your a MQTT broker that is accesible by your main openHAB server.
Install DSMR Reader on your RPI and use the MQTT function to relay the dsmr data to a MQTT broker that is accesible by your main openHAB server.
Relay the serialdata straight from the p1-to-usb-cable to your main server using somesort of usb or serial over ip solution. You can buy such a soltion in the form of a hardwaredevice or build it yourself using a RPI, Linux and the ser2net or USB/IP package.
I installed the P1-USB Cable on my Pi4, started OH3 en installed the binding De Slimme Meter (DSMR Nederland, e-MUCS Belgie). But i can’t get 3 fase data. only “Elektriciteitsmeter” and the Gas readings.
could someone tell me what i did wrong?
The o.e.m. system does non-invasive sub-circuit monitoring.
The original post put forward p1 to USB as an option, not a necessity, I replied to that post and didn’t read the thread, apologies for the confusion.
