I've been playing around w/Homebridge and added the Homebridge-Nest plugin, and my Protects show up, but for one of them I have three instances each of the Smoke and Occupancy instances. I have seven Protects, but only the Kitchen Protect shows up w/multiple instances of Smoke and Carbon Monoxide.
Anyone seen this, and have any suggestions? Can I just Hide the extra ones?

It seems odd, but each Smoke and Carbon Monoxide instance of the Kitchen Protect shows a different serial number if I click on the gear icon on the device instance.
