shelly-iot

Tests: Linux/Mac: Windows:

This library supports reading and controlling Shelly devices.

The library communicates with Shelly devices by REST api (for controlling) and the CoAP protocol with the default Shelly firmware (no flashing of firmware needed!). Because CoAP use multicast UDP packages, the Shelly devices has to be in the same subnet like the host you use the library on. If you use them in a docker container, the container has to run in host or macvlan modus.

The library provides an event driven interface to inform you about status updates that are received using COAP packages.

Usage example

tbd

Method description

ShellyIot(options)

Constructor to init the object. In options you can provide:

• "logger" to be used for debug logging.
• "user" and "password" for Shelly devices with authentication activated. It is assumed that all devices use same credentials

listen(callback)

Starts listening for CoAP packages in the network. Callback is called without parameters after listening started.

stopListening(callback)

Stops listening for CoAP package. Callback is provided for convenience and called synchron without parameters.

discoverDevices(callback)

Sends a multicast package so that all devices should answer with a status package. Callback is provided for convenience and called synchron without parameters.

getDeviceDescription(deviceIdOrIP, callback)

Contacts a known device by Device-ID or by IP to request the device description. Callback is called with the following parameters: error, deviceId, payload, deviceIp

getDeviceStatus(deviceId, callback)

Contacts a known device by Device-ID or by IP to request the device status update. Callback is called with the following parameters: error, deviceId, payload, deviceIp

requestDeviceStatusUpdates(devices)

You can provide an array of Device-IDs or IP to request status updates. They will be emitted as events once received.

callDevice(deviceIdorIp, path, params, callback)

Sends a REST call to a known device by Device-ID or by IP to a certain path with parameters. The result is returned as callback. Callback is called with the following parameters: error, response data

Emitted events

errors

If an error happens while parsing the received data an error event is emitted. Listening will continue, so it is no "fatal error"!

device-connection-status

Emits connection status information for a device. A device is considered "offline" when no status update is received longer then the defined timeframe. Parameters are: deviceId and connection-status true/false

update-device-status

Emits device status update information for a device. Parameters are: deviceId and status payload

disconnect

Emitted when listener disconnects, normally when you call stopListening()

Testing your code

The library also offers a index-dummy.js which offers the same interface then the real library and emits and provides example data.

Supported/Tested devices

• Shelly1 (SHSW-1, Verified)
• Shelly2 (SHSW-21/SHSW-22, Verified)
• ShellyPlug (SHPLG-1, Verified)
• Shelly4Pro (SHSW-44, Reading works, Controlling not verified)
• Shelly Sense (SHSEN-1, Reading not verified)

More details needed to fully implement (Debug log)

• ShellyBulb (SHBLB-1, reading some data may work, no control)
• Shelly2LED (SH2LED-1, reading some data may work, no control)
• ShellyRGBW (SHRGBWW-01, reading some data may work, no control)

Todo

• add example code
• add proper deep testing (maybe using mock-dgram?)
• more detailed docs?
