Raspberry Pi and MQTT-OpenHAB



  • I am a newbei and some stupid questions like cookies:p
    Do i have to use Raspberry Pi for OpenHAB or PiDome?

    My hardware : ENC28J60 Ethernet module + UNO + NRF24L01 Radio so I made connections following http://www.mysensors.org/build/ethernet_gateway and using sketch : http://www.mysensors.org/build/mqtt_gateway without changing any code i got this:

    Started!
    0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
    0;0;3;0;9;version mismatch
    0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
    0;0;3;0;9;version mismatch

    Is it ok?

    I tried everything to install OpenHAB server with Mac but "start.sh" didnt work, i cant open this file, do you have any idea? (Yes i installed Java)


    When Uno is connected with the same network

    • Win8 cmd is running this:****

    If you are planning on using PiDome i would say yes because that is the primary platform focused on, it could theoratically also run on other platforms but we are not done yet supporting a correct way to start.

    If you are planning openhab you can run it on other systems like windows (as you do (win8?)) as well.

    Your first error, i would say double check you are using the latest versions of each (MQTT gateway on the uno and the nodes).

    The second error mentions that it is having a connection timeout which would say it is unable to reach the given ip address, make sure you can connect to the MQTT broker on the uno using for example with mqtt.fx (http://mqttfx.jfx4ee.org/). or other mqtt tools.

    I can nothing say about OpenHAB or PiDome but:

    Started!
    0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
    0;0;3;0;9;version mismatch 
    0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0:
    0;0;3;0;9;version mismatch
    

    Does not look good, it seems an error from the gateway.
