In the blog, we released several articles about ITEAD open source smart home system explaining how to achieve the lighting control and monitoring of the power socket. Next, we want to achieve intelligent control on appliances such as TV and air conditioner in the house.
Here we would like to introduce "ITEAD WiFi IR repeater", which is a hardware device that can be connected to the router via WiFi, and then it can control household appliances through infrared signals. In this way, we can connect cellphone to WiFi and send commands to the repeater to remotely control these appliances.
There are four infrared emitting diodes on the board to achieve omnidirectional emission so that a device can control the appliances in the whole house. There are infrared receiver diodes on the board as well, with which you can learn a variety of codes of remote control buttons – IR carrier frequency width is between 10KHz and 80KHz, which can store 100 key codes and they will not be lost when power down.
WiFi function supports both AP (Access Point) mode and ST (Station) mode,which can be used as hot spot and can be connected directly with cellphones and other control devices or connected to control devices on the same segment via the router. Under ST mode, by mapping configuration via the router, communication between Ethernet and repeater can be achieved, thus to remotely control the appliances in the house through web or cellphone can also be realized.
Although the hardware of IR repeater is not open source, the protocol between repeater and device is open, so the users can write the software or make the devices on their own. By sending commands, it can control the repeater for actions of encoding learning, storing and emitting,etc. so as to achieve control on home appliances with infrared remote control.
We're still collating the product manual and making a small DEMO to show control via cellphone. It is expected that the product will be launched in next week, so stay tuned.
