This is a simple home automation using Eltako funk Series 14

It simulates a button-press and button-release from wired (FTS14-EM) and wireless (EnOcean) buttons which are previous learned into the Eltako devices.
The device status of relais and dimmers are read from the Eltako-bus.

Tested with:

The front-end www/index.html shows every (light-)switch ordered into groups.
Clicking on a switch/button will send a button-press, releasing the button will send a button-release.

    "COM_PORT": "COM7:57600,n,8,1"  # serial USB port where FAM14 is connected
}

Using a REST-API device status is read and button click are simulated.

Example GET read response:

{ "Keuken": {
    "Keuken dim": {"on": 0,"dim": 0},
    "Eettafel": "on": 0}
  },
  "Living": {
    "Zithoek dim": {"on": 0,"dim": 0},
    "Bureau": {"on": 0}
  }
}

Example PUT write data:

• button press {"Living.Bureau":1}
• button release {"Living.Bureau":0}

In this file the Eltako devices are defined with there corresponding buttons. The devices have a name and are ordered in groups.

First you need to program your Eltako devices with addresses and learn the actions on buttons.
Use the Eltako tool PCT14 to do this.

Every device has an address which is the key in the json below.
Set the type of the device, the group and name you want to appear in the App.
The all_off is not a device it only simulates a button press.
The btn specifies the button address and data to be send on the Eltako func RS485 bus.
To find the correct btn.addr and .data use PCT14 (see PCT14_2json.md).
