SmartThings and Homebridge - API Timeouts?

I’m not getting much attention with the issue I opened against the Homebridge project on Github, so thought I’d check with you all to see if anyone had seen this before.

Basically, I have the Homebridge project set up to allow Apple HomeKit to control my SmartThings devices. It has always worked more or less perfectly, until just recently when the API SmartApp has started timing out. There appears to be a hard limit of 20 seconds for the operation, but I can’t figure out why it’s suddenly running into it.

Issue and more details (including screenshots) are here:
