While working on a custom node server, I noticed that I was unable to use my node server in UD Mobile (Android) even though everything looked OK on the admin console. I then tried to bring up another node server and received a similar error. I've tried rebooting the ISY and then performing a sync on UD Mobile. I cleared all data on the app, rebooted ISY, and did a discover. Same error.
java.lang.Error: Node Status Relation Cursor is empty. NodeId: 824. Control:30. 500
On my custom node server, I see similar, just different nodeid and control
I guess it's possible that both me and the other developer are making the same mistake?
