Hi Guys! I'm newbie.I want to do smarthome with MQTT and OpenHab. I start to build a MQTT Gateway (Ethernet Shield w5100). This result :
it's working?. i don't see line "Sending message on topic: mygateway1-out/2/1/1/0/49"

i combine sketch "humiditysensor" and " MQTTGateway". is it right?
thank you for help !
