Don’t work really well
First, there is a communication issue between the Fibaro and the native Homekit app. Fibaro’s app is not able to inform Homekit app that its firmware is already updated, so Homekit continues to show that update is available (and you cannot ignored it, extremely annoying). Second, the “last time opened/closed” (for contact window/door sensors) stoped working (update on 4th March 2018: now it keeps updating randomly, giving me notifications that the doors/window have been opened and that the devices have been tampered. I’ve installed for security purposes but it’s not reliable). Also, there should be an log/history for the last 30 days or so for the times the sensors were opened closed, so it could be used for security purposes too. Currently it only shows the last time (in my case it’s not working anymore, as mentioned above). Last one: it’s NOT optimized to iPhone X yet! I should have bought the ElGato sensors, they have better reviews.
