ElkoEP OpenHAB Web-Service Listener for eLAN-RF-003/eLAN-RF-Wi-003

This small WS Client listens to changes on ElkoEP Control Unit (eLAN-RF-003/eLAN-RF-Wi-003) and sends updates via MQTT to OpenHAB items.

This allows ElkoEP device's state changes to be populated to OpenHAB server in case the state was changed from the outside, e.g. with RFWB-20/G.

This bridge only implements updates from ELKO devices via the MQTT broker to OpenHAB. Controlling the devices from the other direction (from OpenHAB) is not part of this bridge.

The script expects config.json to be present. Please check config.json.dist to start.

Requirements: NodeJS, NPM

Before start: $ npm install

Start: $ node elko-ws-client.js

MQTT

The following topic conventions are assumed:

• elko/control/[DEVICE_ID]:command for sending a commands

OpenHab Items

Configuration

You need to replace following:

• elko.controllers: with list of hostnames/ips of your eLAN-RF-003/eLAN-RF-Wi-003 boxes

• elko.user: user name to login (must be same for all boxes)

• elko.key: SHA1 hash of your password (must be same for all boxes)

• broker: your MQTT broker

  { "elko": { "controllers": ["IP-ADDRESS-1", "IP-ADDRESS-2", ...], "user": "[LOGIN]", "key": "[PASSWORD SHA1 HASH]" }, "ws": "ws://{{HOST}}/api/ws", "state": "http://{{HOST}}/api/devices/{{DEVICE_ID}}/state", "broker": "mqtt://localhost:1883", "regex": "http://[\d+\w+\.]+/api/devices/(.*)" }
