Light kit dead, RFID scanner intermittent

Hey Tulip friends!

Somewhat out of the blue, the managed keyless entry app I built last year has stopped working. Its symptoms started about two weeks ago, and consist of:

  • Light kit works 0% of the time. It appears to be properly configured and I’ve tested two light strips - neither light up at all. It worked 100% of the time before 2021-05-07.
  • RFID scan works intermittently. The scanner itself seems to be totally functional (it beeps even when the app doesn’t respond). I’ve been trying really hard to debug this - it works roughly 50% of the time and annoyingly every time I set aside ten minutes to debug it I can’t get the error to occur.

The gateway’s firmware has been updated, I transitioned the app to Apps @ Edge & Transitions after these issues started. Neither change appears to have affected anything.

Any thoughts on what’s going on?


This app had been running headless, and when the new Shop Floor was enabled it was no longer able to do so.

So, I guess I need to set up an old laptop and put the Player on it. Which is kind of too bad - I don’t want to have another computer running in the shop - but it fixes the immediate problem.
