Signal K Plugin For Sonoff/eWeLink devices
Support for eWeLink switches running the factory firmware.
Devices must first be added using the eWeLink app.
It should work with other Sonoff/eWeLink switches, but no others have been tested.
The plugin can use the eWeLink cloud to communicate with the device, or it can use local LAN mode
The plugin must log in to the eWeLink cloud at least once to use local LAN mode (or if new devices are added).
Once it gets to the cloud once, local LAN mode will work without an internet connection.
