I have this connected to HomeKit to turn off my lights and it doesn't always work. Sometimes it has a pretty bad delay other times it just doesn't work. Hoping for an update that fixes it but until then I would avoid it.

I thought this would send me alerts every time a door opened. Instead it tracks the info inside the app and you need to go retrieve it.

Right now, this does nothing for me without push notifications with Apple's HomeKit. Supposedly, it is still in the works according to the email I received from their tech support. It works great if you just want to keep track of how many times a door or window was opened or closed. You can also set a scene that will turn on or off a smart home device. I do like the small form factor. Come on Elgato or Apple, let's get all of the functionality working!!
