In the next lines I show you how to connect your HA to the ‘slimme meter’ with a small piece of hardware and small extra configuration ‘under’ HA.
First of all you need to make the next hardware:
Second we have to change a few params in the next files:
/etc/config.txt
# Activate UART for 'slimme meter'
dtoverlay=pi3-disable-bt
enable_uart=1
/etc/cmdline.txt
# remove any console command like;
console=ttyAMA0,115200
console= xx
/etc/suoers.d
# Give the user homeassistant enough (hw) rights
in bottom of file;
pi ALL=(ALL) NOPASSWD: ALL
homeassistant ALL=(ALL) NOPASSWD: ALL
As last to do; make the homeassisant user member of the dialout group
sudo usermod -a -G dialout homeassistant
REBOOT the Raspberry Pi
Check in the shell if you can see the telegram data from the ‘slimme meter’ with the next command:
cu -l /dev/ttyAMA0 -s 115200 --parity=none -E q
If you see the next strings after a few seconds … then you hardware is talking to you in the Rpi.
Connected.

The last steps with the configuration issues in HA
You can place all the commands in the configurations.yaml or in the dependent files sensors.yaml and groups.yaml
sensors.yaml
sensor:
- platform: dsmr
port: /dev/ttyAMA0
dsmr_version: 4 # Check your hardware type of 'slimme meter'
groups.yaml
group:
meter_readings:
name: Meter readings
entities:
- sensor.power_consumption_low
- sensor.power_consumption_normal
- sensor.power_production_low
- sensor.power_production_normal
- sensor.gas_consumption
