Wemo Insight Auto

Small Node.js app for autocontrolling Wemo Insight Switch devices. Subscribes an event to get live updates from a group of Wemo devices defined as controllers. Binary state changes on controllers (enter standby, exit standby) switches on/off another group of controlled Wemo devices.

E.g. when the microwave turns on, turn off the AC. And, when the microwave turns back off, turn on the AC.

Install

nodejs and npm are required to install and use this service.

$ npm install -g wemo-insight-auto

Usage

$ wemo-insight-auto -c /path/to/config.json

Config

The script takes it's configuration from a JSON object following this format:

{
    "devControlled": [
        {
            "wid": 762
        }
    ],
    "devController": [
        {
            "wid": 766
        },
        {
            "wid": 708
        }
    ]
}

A config.json.sample file is provided in this package as a template. Feel free to copy and save it as .json on any location, just make sure to point out the full path to this file when running the script with the -c | --config command option (-c /path/to/config.json).

Controlled vs Controller

The devControlled property sets the Wemo devices that are going to be auto-managed by those defined in the devController property. Meaning, when a binary state changes on Wemo devices set under the devController key, it will trigger a signal to turn on/off the devices set under the devControlled key.

Binary State on devController Devices	Action on devControlled Devices
enter standby mode	turn ON Wemo switch
exit standby mode	turn OFF Wemo switch
Wemo switch turned OFF	turn ON Wemo switch

Wemo Device ID

The "wid" key stands for Wemo ID. The value for this key are the last three alphanumeric characters of the Wemo ID, (e.g. WeMo.Insight.xxx). This can be found at the back of the Wemo unit, or from the app at the edit device screen.

Troubleshooting

It might happen the main app script to get stuck on error code EHOSTUNREACH after several hours running (maybe due to poor network performace). To get around this the app can also be run in forever-monitor mode. The app will restart itself everytime an instance of this error occurs.
