-Raspberry pi generate much more eletrict noise than arduino. This is not problem for load CPU, but some time noise random generate corect data for some plugins.

+## RFlink
+is most flexible RF Gatway for control and collect data from wireless sensors
+on 433MHz (686Mhz, 2.4Ghz depents on used transmitter and receiver)
+This solution discrem wide range of sesors, socket, remote controls, door bells,
+meteorological stations, etc. of many manufectures.
+Is suitable for create Home automation.
+RFLink have support for many home automation system etc.:
+   Domoticz (tested), Jeedom, Pimatic, Domotiga, OpenHAB, HoMIDoM

+## RFLink for raspberryPI
+Oreginal version of RFlink run on arduino. **RPi_rflink** directory contain modification free version RFlink for run
+on miniPC raspberryPI. More about this modification version in directory **RPi_rflink**.
