Home Assistant has some support for myStrom products. But I couldn't get functioning the buttons, I get a 401 error. I tried different combinations :
homeassistant:
- type: trusted_networks
trusted_networks:
- 192.168.0.0/21
- 192.168.1.40
- 172.17.0.0/24
- fd00::/8
- type: legacy_api_password
api_password: !secret api_password
http:
binary_sensor:
- platform: mystrombut it doesn't work and the legacy_api_password is deprecated and will be dropped in a future release.
So I decided to create this gateway.
The goal is to have binary_sensors for single, double, long, touch, wheel_final event and sensors for battery level and wheel event (italic only available for Button Plus) automatically created in Devices of Home Assistant. So Home Assistant can suggest Automations.
You need to have a myStrom Wifi button with the minimal Firmware version: 2.74.10.
Please note the MAC address of your button. (only the numbers or letters). It will be know as [BUTTON_MAC]
You find this address on the purchase box or in myStrom application.
or
On a Button Plus, the MAC address is written on the bottom:
Identify the IP address of your wifi button. It will be known as [BUTTON_IP] .
Identify the IP address of this GATEWAY. It will be known as [GATEWAY_IP] .
Note that the port 8321 is the default port of the gateway and can be modified in the settings.json file.
The following command will erase the previous actions of the button (single , double , long click and touch) and replace them by a generic action.
The actions created in the app seem to be working independently.
Run the command :
curl -v -d "generic=get://[GATEWAY_IP]:8321/api/mystrom/gen&single=&double=&long=&touch=" http://[BUTTON_IP]/api/v1/device/[BUTTON_MAC]For the myStrom Wifi Button, the button has to be plugged to a charger and press to communicate with your Wifi.
For the myStrom Wifi Button +, you should remove the batteries and insert them again.
A positive setup should look like that:
* Trying [BUTTON_IP]...
* TCP_NODELAY set
* Connected to [BUTTON_IP] ([BUTTON_IP]) port 80 (#0)
> POST /api/v1/device/[BUTTON_MAC] HTTP/1.1
> Host: [BUTTON_IP]
> User-Agent: curl/7.52.1
> Accept: */*

"single": "",
"double": "",
"long": "",
"touch": "",
"generic": "get:\/\/[GATEWAY_IP]:8321\/api\/mystrom\/gen"
* Curl_http_done: called premature == 0
* Closing connection 0
The "\/" in the generic URL are normal.
Update and rename the "resources/settings.json.sample" into "resources/settings.json"
Please add the [BUTTON_MAC] and a short uniq name of your choice [CHOOSEN_NAME] in the section "button" or "buttons+" of the file "resources/settings.json". Personnally I have chosen the color of the rubber band as [CHOOSEN_NAME].
"button":{
"123456789ABC" : {"name":"green"},
"0123456789AB" : {"name":"orange"},
"[BUTTON_MAC]" : {"name":"[CHOOSEN_NAME]"}
},For a button plus, you have to set the initial level [LEVEL] (as integer), the minimum [LEVEL_MIN] (as integer) and the maximum [LEVEL_MAX] (as integer). The [LEVEL] is controlled by the "wheel" event which is a difference between -127 and +127. It will increase to the [LEVEL_MAX] and decrease to the [LEVEL_MIN].
"button+":{
"3423456789AB" : {"name":"plus 1", "level_min": 0 , "level_max":255, "level":0},
"[BUTTON_MAC]" : {"name":"[CHOOSEN_NAME]", "level_min": [LEVEL_MIN] , "level_max": [LEVEL_MAX], "level": [LEVEL]}
}Start the gateway with the command:
python3 mystrombutton2mqtt.py ./resources/settings.jsonThe following topics for each button will be published:
## The Discovery Topics
## --------------------
[PREFIX]/sensor/myStrom/[BUTTON_MAC]_battery/config
# only if it's a "Button Plus"
[PREFIX]/sensor/myStrom/[BUTTON_MAC]_wheel/config
[PREFIX]/sensor/myStrom/[BUTTON_MAC]_level/config
[PREFIX]/binary_sensor/myStrom/[BUTTON_MAC]_single/config
[PREFIX]/binary_sensor//myStrom/[BUTTON_MAC]_double/config
[PREFIX]/binary_sensor/myStrom/[BUTTON_MAC]_long/config
# only if it's a "Button Plus"
[PREFIX]/binary_sensor/myStrom/[BUTTON_MAC]_touch/config
[PREFIX]/binary_sensor/myStrom/[BUTTON_MAC]_final_wheel/config
[PREFIX]/binary_sensor/myStrom/[BUTTON_MAC]_level/config
## The state topics
## ----------------
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/single
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/double
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/long
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/battery
# only if it's a "Button Plus"
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/touch
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/wheel
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/wheel_final
myStrom/wifi_buttons/[CHOOSEN_NAME]_[BUTTON_MAC]/level[PREFIX] will be the prefix you specify in the ./resources/settings.json
For HomeAssistant, according to the documentation, the default discovery prefix is homeassistant
On Home Assistant, you should have the same [MQTT_BROKER_IP] in your "configuration.yaml":
mqtt:
broker: [MQTT_BROKER_IP]
discovery: trueOnce the gateway started, Home Assistant will show the button(s) in "Configuration" > "Devices" as "Wifi Button [CHOOSEN_NAME]" with "MQTT" in the integration column and "myStrom AG" as the manufacturer
The battery information will be updated after each button action or every 12 hours when the button does a heartbeat.
If you run the gateway on a raspberry pi, you may want to run it as a service. To do so, create a file:
sudo vi /lib/systemd/system/mystrombutton2mqtt.servicePaste this code and replace the [DIRECTORY_PATH] by the correct one:
[Unit]
Description=myStrom Wifi Buttons 2 MQTT Gateway Service
After=multi-user.target
Conflicts=getty@tty1.service
[Service]
Type=idle
User=pi
WorkingDirectory=[DIRECTORY_PATH]
ExecStart=/usr/bin/python3 [DIRECTORY_PATH]/mystrombutton2mqtt.py [DIRECTORY_PATH]/resources/settings.json
KillSignal=SIGINT
Restart=always
[Install]
WantedBy=multi-user.targetEnable the service:
sudo systemctl enable mystrombutton2mqtt.serviceStart the service:
sudo systemctl start mystrombutton2mqtt.serviceCheck if it's active:
sudo systemctl status mystrombutton2mqtt.servicecaThe included Dockerfile will build a basic image off python:3. Running docker-compose up will build and start the image, and will mount the resources/settings.json file.
You can use the CREATE AUTOMATION WITH DEVICE UI Automation Generator.
Under Do something when..., the useful choices are:
- myStrom Wifi Button [CHOOSEN_NAME] ([BUTTON_MAC]) single turned on
- myStrom Wifi Button [CHOOSEN_NAME] ([BUTTON_MAC]) double turned on
- myStrom Wifi Button [CHOOSEN_NAME] ([BUTTON_MAC]) long turned on
- myStrom Wifi Button [CHOOSEN_NAME] ([BUTTON_MAC]) touch turned on (Button plus only)
- myStrom Wifi Button [CHOOSEN_NAME] ([BUTTON_MAC]) battery battery level changed
the device_id: 240e4c5a16da4b96a45e060b184ed880, platform: device and type: turn_on have been added by the UI Automation Generator. Written manually, they would be replaced by: platform: state and to: "on"
