@andy5211d this is good news! I'm going to take a look at HA's direct access. I hope it works, I really would like the remote programming.

@andy5211d It seems that MYScontroller does not work when MQTT is involved. I've tested both sketches, GatewayW5100 and GatewayW5100MQTTClient, and only GatewayW5100 could connect to MYSController.

Hi All,

I've successfully implemented an ethernet gateway with MQTT using an Arduino Ethernet board. Everything works just fine and I am able to receive data from the nodes and send data to the nodes.

The next step would be to get FOTA up and running and this is where I'm stuck. I'm using the GatewayW5100MQTTClient example program as my base with changes to the IP, MAC and MQTT settings.

When trying to connect to the GW using MYSController with the TCP/IP settings, I get an "Error on connect: connection refused" error.
This makes me believe that I still need to add code in the GW sketch to handle incoming requests? If this is the case, can someone please point me in the right direction? If the GW code and mysensors library are supposed to manage requests, where can I start to do my debugging?

Thanks in advance
Jan
