So we've seen a few logs that worry us as the node subscription was started but then never completed. No stacktrace/error, no timeout, no success. Seems that it just deadlocks.
This was however in all cases Nanoleaf devices, that are known to be unstable and reset often.
What if the device resets just while setting up subscriptions?
It's worth investigating and at least protect against. This adds a timeout to setting up the subscription and logs a warning if the timeout expired.
