@Kurtsejr i think for the best erase or move whole libraries out of the way and put in fresh in cos i notice two folder differently one was "my-sensor" other one is "MySensors" folder myself would use "MySensors" from the website i unrar place in that one it work so well then other one ... so worth a try ;-) (thats happen when i try other one saying check wire) so try other one and softspi then it would say "started" on the serial montior on arduino IDE

arduino/libaries/Mysensor/utility/rf24_config.h open with geany for windows and //#define SOFTSPI edit it save / reupload sketch i didnt use serial gateway i use mqtt gateway thou.. i will check later with serial gateway never tried.. still building up and learning and gets better now lol

r u sure add the addon folder.. org.openhab.binding.mqtt-1.6.2 then check in opehab config.. add ur ip of ur arduino gateway and port thats happens to me then end up got it working byself when restart and disconnect the mqtt client from @Jerady ... i check ur debug too many try remove many addons and focus on one thing a time and will able to help ;-) like i did...

got all the sensor with nrf24 senting to arduino mqtt gateway fine and communcation to open hab on pc or raspberry pi works well but... would like add to control those pins on the mqtt gateway as well ? i dont see any info on mysensor / forums? i think i gotta to play with it over the weekend ;-) any quick tips?
thanks

thanks ;-)

@amitach im able see on mqttfx on windows with incoming msg of arduino senting temp and hum (MyMQTT/21/0/v_HUM with 41.0 below.. appear to be working on this machine while the openhab is running as server on this pc for testing .... ive check the openhab test.items
i rename the line...

String sketch20 "Cupboard Temp [%s °C]" (sketch,all) {mqtt="<[MyMQTT/21/0/V_TEMP:state:default]"}

nothing is updating....

@Jerady works with older verions of MQTT.fx 0.0.12 on win 7 32 bit .. the newer one is only for 64 bit machine.. cheers
