MOES UFO-R11 stops responding after 15-30 minutes and does not recover

[insleys]

What happened?

Roughly 4-5 weeks ago, I noticed that my UFO-R11 IR devices stopped working reliably. I have determined that somewhere between 15-30 minutes after a UFO-R11 is added, it no longer responds to any published topics to enable/disable learning or to send an IR code. If a topic is published to send an IR code every 10-15 minutes, the devices continue to work - this is my workaround at present, but I have concerns that this will affect battery life.

The only way to recover is to re-join the device or to trigger an interview. As this wasn't happening when I first bought the devices 6+ months ago, I can only assume this is a regression. I have tested multiple devices.

What did you expect to happen?

Regardless of how much time elapses between interactions with the device, it should respond and work as expected.

How to reproduce it (minimal and precise)

1. Join a UFO-R11 to the network
2. Do not use the device for 15-30 minutes
3. Try to send an IR code, which will silently fail
