It's been a pretty big week for HomeKit and Apple news, from the long-awaited T9 thermostat upgrade to the new Nuki Lock - and more. Keep up to date with what's new in the HomeKit Insider podcast.

Honeywell HomeKit's addition to its T9 thermostat means it has finally fulfilled its promise. While the Honeywell T5 Lyric thermostat has had HomeKit support for years, the T9 is especially welcome for what it now brings to smart homes using the Apple system.

Mainly, the difference between the two models is that the T9 differs includes support for external sensors. These sensors allow the thermostat to adjust the temperature for the room you are in and not just depending on where the thermostat is.

Still, Ecobee could be known for its thermostats, but it wants to do more and, as part of it, announced that it is changing its name to its home monitoring system in Ecobee Smart Security. With its smart Ecobee Haven platform, the company's service includes professional monitoring, with video confirmation, which can then send emergency services home when needed.

In addition, Nuki's new Lock 3.0 has been released, Level Inc has announced the acquisition of Dwelo - and Targus has included Find My in the latest backpack set to be released in 2022.

I had a few questions from listeners to solve this week. Keith Morrison wanted to know which smart thermostat would integrate well with Eve Thermo hits through HomeKit.

Simon Salvin asked if the new Ikea smart blinds are compatible with HomeKit. Chris sent us a message asking if there was a HomeKit freezer monitor to help you get alerts if your freezer thawed when it shouldn't.
