Hello,
I'm running OpenHAB 2.4.0 on Windows 7 and I followed the instructions to install mysensors (org.openhab.binding.mysensors-2.4.0-SNAPSHOT.jar) Now I not able to connect the gateway to the controller. I think the gateway code is fine. When I check the ports on the controller, there is no service listening on port 5003.

Installed bundles:

The gateway works fine as MQTT client and it is able to connect to MQTT broker at port 1883 but I would like to make it work as regular mysensor ethernet gateway.

hello,
my bad. The second capacitor has not been properly attached, now the node is communicating! :)
Thank you for the help.

note: 10uF wasn't enough, 110uF works fine for me

I increased the capacity to 100uF and replaced delay() for wait() but no difference. Thanks for the hint about sender in receive() method, I will fix the functionality when the communication works. Any other idea?

I use USB 3.0 HUB power with 10uF attached capacitors for gateway and node

Hello,
I have MQTT ethernet gateway based on W5500 with attached relay connected to OpenHAB. I am able to control the relay and it works fine. The code of the gateway:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_RF24
//#define MY_RADIO_NRF5_ESB
//#define MY_RADIO_RFM69
//#define MY_RADIO_RFM95

// Enable gateway ethernet module type
//#define MY_GATEWAY_W5100
#define MY_GATEWAY_ENC28J60


#define MY_GATEWAY_MQTT_CLIENT

// Set this nodes subscripe and publish topic prefix
#define MY_MQTT_PUBLISH_TOPIC_PREFIX "P"
#define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "S"

#define MY_CONTROLLER_IP_ADDRESS 192,168,0,50
#define MY_PORT 1883

// Set MQTT client id
#define MY_MQTT_CLIENT_ID "M1"

But the messages are not going to MQTT broker, I use MQTT.fx, only when the node is started, there are only initiation messages:

P/0/255/0/0/18 2.3.1
P/0/255/3/0/11 Relay & Button
P/0/255/3/0/12 1.0

There are some debug errors in gateway output:
