Interface for Sonoff devices running v3+ Itead firmware.
Control Sonoff devices running original firmware, in LAN mode.
To control Sonoff switches running the V3+ Itead firmware (tested on 3.0, 3.0.1, 3.1.0, 3.3.0), locally (LAN mode).
This will only work for Sonoff devices running V3+ of the stock (Itead / eWeLink) firmware. For users of V1.8.0 - V2.6.1, please use PySonoffLAN
This module provides a way to interface with Sonoff smart home devices, such as smart switches (e.g. Sonoff Basic), plugs (e.g. Sonoff S20), and wall switches (e.g. Sonoff Touch), when these devices are in LAN Mode.
LAN Mode is a feature introduced by manufacturer Itead, to allow operation locally when their servers are unavailable. Further details can be found in the eWeLink LAN Mode guide.
Since mid 2018, the firmware Itead have shipped with most Sonoff devices has provided this feature, allowing devices to be controlled directly on the local network using a WebSocket connection on port 8081.
- Discover all devices on local network
- Read device state
- Switch device ON/OFF
- Listen for state changes announced by the device (e.g. by physical switch)
- Activate inching/momentary device, with variable ON time (e.g. 1s)
- Documentation: https://pysonofflanr3.readthedocs.io.
$ pip install pysonofflanr3
Usage: pysonofflanr3 [OPTIONS] COMMAND [ARGS]... A cli tool for controlling Sonoff Smart Switches/Plugs in LAN Mode. Options: --host TEXT IP address or hostname of the device to connect to. --device_id TEXT Device ID of the device to connect to. --inching TEXT Number of seconds of "on" time if this is an Inching/Momentary switch. -l, --level LVL Either CRITICAL, ERROR, WARNING, INFO or DEBUG --help Show this message and exit. --api_key KEY Needed for devices not in DIY mode. See https://github.com/mattsaxon/pysonofflan/wiki/Finding-the-API__Key Commands: discover Discover devices in the network listen Connect to device, print state and repeat off Turn the device off. on Turn the device on. state Connect to device and print current state.

All common, shared functionality is available through
x = SonoffSwitch("192.168.1.50")
Upon instantiating the SonoffSwitch class, a connection is initiated and device state is populated, but no further action is taken.
For most use cases, you’ll want to make use of the
parameter to do something with the device after a connection has been
initialised, for example:
async def print_state_callback(device): if device.basic_info is not None: print("ON" if device.is_on else "OFF") device.shutdown_event_loop() SonoffSwitch( host="192.168.1.50", callback_after_update=print_state_callback )
This example simply connects to the device, prints whether it is currently “ON” or “OFF”, then closes the connection. Note, the callback must be asynchronous.
Module-specific errors are raised as Exceptions, and are expected to be handled by the user of the library.
- Free software: MIT license
- Enabled code to work if device IP address changes
- Fixed faulty CLI introduced with 1.1.3 (https://github.com/mattsaxon/pysonofflan/issues/65)
- Removed previous workaround code for earlier version of zeroconf (<=24.4)
- Fixed issue of reconnection that device remains unavailable until state changes
- Fixed retry code for strip type devices
1.1.2 (deleted release)
- Optimisations to deal with later zeroconf versions which have some different behaviour
- Improved error handling of unexpected errors
- First release on PyPI.
- Forked from PySonoffLAN package (courtesy of Andrew Beveridge)
- Works on V3 Itead firmware using mDNS for service discovery and REST for service invocation
- Supports DIY mode as well as ‘standard’ mode (for standard mode API key is needed to be obtained, e.g. by sniffing LAN)
- Supports all known devices for switching, although no sensors added at this point
