Hi Tony,

I would love to make a DMX plugin to but just do not have the time. I use DMX at work every day and you can do so much with it but it is getting phased out with ethernet based protocols like Artnet and ACN.

Anyway I think you should be able to do what you want to but I would first get the fade time changing from Homeseer so I have adapted your code and removed a couple of unused things. I can not try it as I am not sure which library you are using so if you can send it to me or post it that would help and I will try and set up a test rig. (This may be at work

)

As you will see device 3 is now the fade time so set up the device in homeseer and try different timings to make sure this works.

The next step will be to remove the Wait/delay in the code as this is not good and is stopping the code from running like you are seeing.

Code:

//For serial set to 0 and for Ethernet set to 1
#define ISIP 1

//Do NOT modify these
#if ISIP == 1
#include <EEPROM.h>
#include <SPI.h>       
#include <Ethernet.h>
#include <EthernetUdp.h> 
#endif

Thanks Greig, I guess device 3 will work to set delay but during the fading the communication between hs will be freezed.
I send you by email the library.
Thanks
