Looking at upgrading the 8 (wired) detectors I have in my home. With the burgeoning HomeKit market, I was really hoping to go HomeKit for the smoke detectors. I don't yet have any HomeKit devices, but that will change (lights, locks, garage door opener, etc) over the next year or so. Nest isn't HomeKit compatible, and given their parent company, I don't hold out much hope they will be. But their latest models have fantastic reviews and I'm tempted to go with them despite the fact they'd be an 'outlier'. Onelink's reviews still aren't as good as Nest's, though some reviewers have given them slightly higher marks than they used to get. Common complaints from reviewers seem to focus around flakey push notifications and a pretty thin integration with HomeKit ... though both of these things are supposedly being addressed by First Alert and can be improved with firmware updates. Right now, I'm leaning towards Nest, but was wondering if people here have good stories about Onelink that would convince me using them is the right way to go.
