I am trying to build up a Mysensors with Wired ethernet to the gateway with W5100 and RS485 bewteen nodes, is there something that can help me with this configuration?
Everything looks weel from the monitor serial but domoticz is not able to connect to the gateway!

@Strixx Did you finally solve this issue?
I am new in my sensors and I have a single ethernet gateway with W5100 and one DS18B20 connected.
The gateway is correctly found but then I found too many child:

After one day also devices and node are multiplied.....
It looks that the gateway is rebooting many times and creating always new node and new devices....

I don't know if the reasin is the memory of the gateway not enough.

Another strange thing is that in the gateway I set:

#define MY_NODE_ID 1

but the gateway is found with id=0.

I have another problem quite old but didn't find solution: data are trasnferred to device with only one decimal....

I have a similar issue with domoticz and ethernet gateway wired with W5100 ethernet shield.
On the ehternet gateway only one temperature sensor is attached (DS18B20).

I have checked that also nodes list is strange:

Any suggestion?
I will try by changing the protocol to MQTT but you look to have same problem (you have radio) and so the way to connect the gateway doesn't look to have influence.
