## Questions & Answers

**Q: When using the iOS platform - can I combine Matter and HomeKit-enabled accessories in an automation or scene?**
A: Yes you can. For automations, Apple Home makes no difference whether your devices were added to your home through HomeKit or Matter.

**Q: Eve Door & Window is a Minimum Thread Device (MTD) – but what does that mean?**
A: Thread makes your smart home network more responsive, the only other thing you need is a home hub (Thread border router). Battery-operated Thread accessories, such as Eve Door & Window, represent endpoints in your Thread network.
