RFLink binding

Add-ons Bindings

Hi,

I decided not to wait for the binding and coded everything in python and openhab (RPI3 and OH2 as platform):

  • Made a python script that reads/writes data from RFLINK (USB) to/from MQTT (also on RPI3) ;
    This merely a s/w gateway that reads data from rflink and sends it (unmodified) to MQTT and vice versa ;
  • In openhab2 I defined two items : rflinkTX and rflinkRX
String rfLinkRx "rfRx: [%s]" {mqtt="<[mybroker:rflink/rx:state:default]"}
String rfLinkTx "[%s]" {mqtt=">[mybroker:rflink/tx:command:*:default]"}
  • In a rule I parse the incoming string and take action :
rule "rfLinkRX"
    when
        Item rfLinkRx received update
    then
        //parse data here...
        //pushover("rfLink: " + rfLink.state) //test 
    end
  • For sending commands also a rule is created (per item):
rule "Lamp1Button"     // lamp on/off button
    when
        Item lamp1Button changed
    then
        rfLinkTx.sendCommand("10;Kaku;00004b;2;" + lamp1Button.state)
    end

I know this is not as convienent as having a binding but it is a ‘good’ workaround to get the gateway going.
