Kit Description
This kit provides a remote-controlled mains switch. It is inserted in between a common mains plug and an electrical device (for example, a lamp). It provides a switch for the electrical device.. The power to the device connected into the switched plug will be either on or off.
The kit features Wifi and a 866Mhz radio. The kit may be connected to a wireless network and through this to the internet. Connection to the internet is required for remote operation. If the device is not connected to the internet, it can only be controlled by devices on the same network.
If the kit is connected to the internet, firmware modifications can be installed automatically or pushed to the device on demand.
Firmware is open-source and may be end-user modified (see http://www.singingcat.net)
The kit may be switched on or off, by either
- An Android App
- An iPhone App
- An open API
- Direct Commands (via WiFi or Radio)
The protocols and interfaces are open-source. The kit can be used to implement custom automation.
Example Applications
- Switching on a light when someone comes home (based on smartphone gps or wireless)
- Switching off a light when someone leaves (based on smartphone gps or wireless)
- Powering down computers or televisions when not in use
- Automatically Opening or Closing roof windows, depening on temperature and/or rain
- Switch lights on/off with a remote-control
- Open Front-Gates with a remote-control
