@redloro It seems that if I run smartthings-nodeproxy and smartthings-mqtt-bridge at the same interface on the same machine, only the MQTT Bridge Smart App gets the button press event. Dash Button won’t do anything with the selected switch. I can get around this issue by setting the IP & MAC addresses of the MQTT Bridge DTH to a different interface (say wifi vs. wired LAN). Is there a proper solution or is this a limitation of SmartThings?
