Virtual Smart Hub for TP-Link Kasa Smart Home

Designed to be run on a LAN server, e.g. on a Raspberry Pi.

How to

Install as global npm packages. Then create configuration file and start with

kasa-smart-hub /path/to/config.json

Config

Configuration can be in multiple formats. Most likely you want to use config.js or config.json.

logFile

links

Object that contains "linked" switches that are always executed together.

timer

__default

Default fallback timer. Can be set to zero to disable.

Config Example

import path from 'path';
import fs from 'smart-fs';

export default {
  logFile: path.join(fs.dirname(import.meta.url), 'kasa-logs.txt'),
  links: {
    'kitchen-lights': [
      // when either of these is switched on / off the other one will also switch on / off
      'Kitchen Counter Lights',
      'Kitchen Ceiling Light'
    ]
  },
  timer: {
    __default: 8 * 60 * 60, // switch off everything after eight hours
    'Bathroom Fan': 60 * 60 // switch off after one hour
  },
  on: {
    'Plant Light': ['We 21:00'] // switch on every Wednesday at 9pm
  },
  off: {
    TV: ['02:00'] // switch off every day at 2am
