myStrom

There is currently support for the following device types within Home Assistant:

Lights and switches

The myStrom integration allows you to control your myStrom Wi-Fi Bulbs and Wi-Fi Switches. Make sure that you have enabled the REST API under Advanced in the web frontend of the switch.

Supported devices are:

  • Switch CH v1 (101)
  • Bulb (102)
  • LED strip (105)
  • Switch CH v2 (106)
  • Switch EU (107)
  • Switch Zero (120)

Configuration

To add the myStrom integration to your Home Assistant instance, use this My button:

Check if you are able to access the light located at IP_ADRRESS. The details about your light is provided as a JSON response.

$ curl http://[IP_ADDRESS]/api/v1/device/[MAC_ADDRESS]

{
  "MAC_ADDRESS": {
    "type": "rgblamp",
    "battery": false,
    "reachable": true,
    "meshroot": false,
    "on": true,
    "color": "0;0;100",
    "mode": "hsv",
    "ramp": 409,
    "power": 5.1,
    "fw_version": "2.25"
  }
}

Binary Sensor

The mystrom binary sensor platform allows you to use myStrom Wifi Buttons with Home Assistant. The myStrom Wifi Buttons support three and the myStrom WiFi Button + four different push pattern:

  • single: Short push (approx. 1/2 seconds)
  • double: 2x sequential short pushes (within 2 seconds)
  • long: Long push (approx. 2 seconds)
  • touch: Touch of the button’s surface (only affective for WiFi Button +)

The first usage of the pattern will create the binary sensor for the pattern. If the WiFi Button is pushed one time then a binary sensor for the single pattern will be created. The same applies for the other patterns. With the second usage of the pattern the binary sensors become fully functional.

The buttons will give you feedback with its built-in LED:

  • white then green: Pattern was submitted successfully
  • white then red: There is a problem with the communication

To use your myStrom WiFi Button in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
binary_sensor:
  - platform: mystrom
The firmware version 2.56 doesn't support TLS/SSL. This means that you are only able to use the WiFi Buttons if you are using plain-text communication between Home Assistant and the clients/entities.

Setup of myStrom Buttons

You need to configure every button to make it work with Home Assistant. First connect the Wifi Buttons to your wireless network. Once a button is connected you have three minutes to set the actions for the push patterns if the button is not charging. The fastest way is to use curl. Check the documentation of the WiFi Button for further details about the implementation (http:// is replaced by get:// or post://). action is the name of the corresponding push pattern (see above).

The endpoint that is receiving the data is http://[IP address Home Assistant]:8123/api/mystrom. If you have set an api_password then this needs to be included in the URL.

With api_password:

curl -d "[action]=get://[IP address Home Assistant]:8123/api/mystrom?api_password%3D[api_password]%26[action]%3D[ID of the button]" \
    http://[IP address of the button]/api/v1/device/[MAC address of the button]

Without api_password:

$ curl -d "[action]=get://[IP address Home Assistant]:8123/api/mystrom?[action]%3D[ID of the button]" \
    http://[IP address of the button]/api/v1/device/[MAC address of the button]
{
  "[MAC address of the button]": {
    "type": "button",
    "battery": true,
    "reachable": true,
    "meshroot": false,
    "charge": true,
    "voltage": 4.292,
    "fw_version": "2.56",
    "single": "get://[IP address Home Assistant]:8123/api/mystrom?single=[id of the button]",
    "double": "",
    "long": "",
    "touch": ""
  }
}

A complete command to set the URL for a double click could look like the example below:

curl -d "double=get://192.168.1.3:8123/api/mystrom?double%3DButton1" http://192.168.1.12/api/v1/device/4D5F5D5CD553

With an api_password:

curl -d "double=get://192.168.1.3:8123/api/mystrom?api_password%3Dapi_password%26double%3DButton1" http://192.168.1.12/api/v1/device/4D5F5D5CD553

The command-line tool mystrom is a helper to configure myStrom buttons.

If you have set login_attempts_threshold and forget to include the api_password for an action and that action is triggered then after the threshold is reached will the button no longer work because it is banned. See IP filtering and banning about how to revert the banning.
