Home Automation Adventures

Welcome to my Home Automation Adventures. If you are like me, new and interested in Human-Machine Interaction (HMI) follow me on my journey as a novice in this topic struggling through this vast wealth of information and learn what works for me.

My goals are to integrate devices such as a heat pump, lights, and smart plugs in a family- and spouse-approved manner into a new-build house and have it controlled with an aesthetically pleasing dashboard.

How to integrate the stromleser

How to integrate the stromleser.tasmota

Helpful links

Start by connecting the stromleser.tasmota to the IR Interface of the Smartmeter and provide it with power.

After booting, the device creates its own WiFi Hotspot.

You can connect to the default WebGUI by joining the WiFi Hotspot and opening http://192.168.4.1 in your Web Browser.

Configure the device to your preferences
(IP-Address, etc.)

IMPORTANT: DO NOT UPGRADE THE FIRMWARE VIA THE WEB SERVER !

You need to use a customized version and manually upload it to the device.

Configure the MQTT settings

Add the Tasmota integration into Home Assistant (you should be prompted automatically).

For Tasmota to read the values, you need to add the correct script for the Smartmeter you are using.

After adding the code, the values will be displayed.

e.g. Landis + Gyr E320

>D
>B
=>sensor53 r
>M 1
+1,3,s,16,9600,E320,1
1,77070100010800ff@1000,Verbrauch,kWh,E_in,3
1,77070100020800ff@1000,Einspeisung,kWh,E_out,3
1,77070100100700ff@1,akt. Leistung,W,Power,0
1,=h--
1,77070100600100ff@#,Server-ID,,Meter_Number,0
#

To get all available values you need to unlock the Smartmeter otherwise it will only provide total consumption.

After entering the PIN into the Smartmeter you need to

  • set the option “INFO PIN” to off (light on for 5 sec)
  • set the option “INFO inf” to on (light on for 5 sec)

To display the correct unit of measurement in Home Assistant, you need to customize the sensor.

Add the below code (for Landis + Gyr E320) to the “configuration.yaml” file to set the unit of measurement (kWh).

homeassistant:
  customize_glob:
    sensor.tasmota_e320_e_in:
      unit_of_measurement: "kWh"    
      device_class: energy

      last_reset: 1970-01-01T00:00:00+00:00
    sensor.tasmota_e320_e_out:
      unit_of_measurement: "kWh"    
      device_class: energy

Start by placing the wasserleser over the metering wheel.

Run the setup wizard on your mobile device, it needs Bluetooth to configure the WiFi interface. After the initial setup, you can use the assistant in the Smartmeter app to configure the MQTT settings for Home Assistant.
