This JavaScript webapp I hosted on GitHub allows to control a FHEM instance via a simple configurable touch interface with one single touch! It is even possible to display it on a very small 320×240 pixel display, e.g. on a raspberry pi. In my case I tested it only with the MAX! heating controllers, but it should work with more devices controlled by FHEM.

Requirements

Installed latest node.js and npm and running fhem.

Build & deploy

Run grunt for building and grunt serve for preview. After grunt you can copy the content of the dist folder to your own web server.

How does it look like?

When nothing is selected:

After clicking on a button:

After getting a successful answer from the FHEM server the button turns green for a few seconds:

Configuration

In config/config.json lies an example configuration file. It starts with the configuration of the URL to the fhem web interface and is followed by the configuration of the different configuration sets. E.g.:

{
  "url": "http://127.0.0.1:8083/fhem?room=MAX&cmd=jsonlist2&XHR=1",
  "groups":
  [
    {
      "groupname": "Room x",
      "buttons": [
        {
          "name": "19°C",
          "cmd": "set",
          "arg": "desiredTemperature",
          "room": "MAX",
          "val": "19.0",
          "devices": [
            {"deviceid": "dev1"},
            {"deviceid": "dev2"}
          ]
        },{
          "name": "off",
          "cmd": "set",
          "arg": "desiredTemperature",
          "room": "MAX",
          "val": "off",
          "devices": [
            {"deviceid": "dev1"},
            {"deviceid": "dev2"}
          ]
        }
      ]
    },
    {
      ...
    }
  ]
}

In this example you have a group with two buttons, each button controlls two devices. You can set the desiredTemperature to 19 degrees and off. As arg it is allowed to set anything the fhem web interface would accept, too.
