ISKRA 550 SMR 5.0 AM550 P1 Connection

#1

Hi,

I am using Home Assistant together with an P1 Cable to read out an ISKRA 550 SMR 5.0 AM550 meter.
I can’t seem to get it to work with the settings below, what i am doing wrong.

sensor:

  • platform: dsmr
    port: /dev/ttyUSB1
    dsmr_version: 5

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

Thanks in advance

Hi Martijn,

Found the solution, works out-of-the-box, if you have the usb port right :slight_smile:

sensor:

platform: dsmr
port: /dev/ttyUSB0
dsmr_version: 5
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

Problem Solved

Okay i know a bit more but it still doesn’t work.

when i monitor my ttyusb0 i can see the values, they are correct … checked it manually with the display of the smart meter. So this tell me my cable is okay, my driver is okay, my baudrate is ok … but why … is Hass not picking it up in the sensors … i am missing something … but what … i am on a centos 7 minimal install …

I monitor the output with this command

cat /sys/kernel/debug/usb/usbmon/0u
