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?

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

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

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:
