What exactly do you mean by "Adrino board"? Are you referring to Arduino boards? If so, are you using the old SmartThings ThingShield? Or a WiFi/Ethernet connectivity solution?
Take a look at my HubDuino thread, as it is a continuation of my ST_Anything work over on SmartThings. It has support for both the old ThingShield as well as WiFi/Ethernet solutions.
Note: During my early testing with the ThingShield, it did not like high-numbered Zigbee channels. I switched my Hubitat hub to Zigbee channel 20 and it connected quickly.
