node-red-contrib-rfxcom
A collection of Node-RED nodes to send and receive home automation commands and data using an RFXCOM RFXtrx433E home automation controller. Also compatible with the older RFXtrx433 transceivers.
Install
Use npm to install this package locally in the Node-RED data directory (by default, $HOME/.node-red):
cd $HOME/.node-red
npm install node-red-contrib-rfxcom
Alternatively, it can be installed globally:
npm install -g node-red-contrib-rfxcom
The nodes will be added to the palette the next time node-RED is started.
Nodes included in the package
rfx-lights-in Receives messages from 'lighting' type devices such as remote controls, PIR sensors used as light switches, and some types of doorbell.
rfx-lights-out Sends messages to 'lighting' type devices including switches, dimmers, and some types of relay.
rfx-PT2262-in Receives messages from devices using the PT2262 chipset. many no-name remote controls and alarm systems use these chips
rfx-PT2262-out Sends messages to devices using the PT2262 family of chips.
rfx-sensor Receives messages from temperature, humidity, pressure and other weather sensors.
rfx-meter Receives messages from wireless energy monitors such as OWL
Basic help text is provided for each node. Additional information is available in the 'RFXmngr.exe' program supplied with the RFXtrx433E, and more details may be found in the SDK documentation, available on request from RFXCOM.
Example flow
The following Node-RED flow listens to an Oregon temperature sensor, and turns a HomeEasy relay on if the temperature is 9.5 degrees or less, off otherwise:
