Just upside down, changing your Keychain router password doesn’t update Homekit devices with the new password, as it does for all Apple devices. After a week without Homekit, I finally inserted my old AirPort Extreme into my main router. I knew I should have done this in the beginning. I split the 2 ghz and 5 ghz bands (I wish I could turn off 5 ghz), called the 2 ghz network “Homekit” and started re-adding the devices. I also took this time to manage my router to reserve DHCP addresses for all smart devices and give everyone a new name; seeing six identical names “Meross Smart Bulb” was a bit annoying. They all start at 192.168.0.200, so they appear at the bottom of the list of attached devices instead of randomly crowding the list. The best part about migrating all my Homekit devices to a separate network is that I can connect my main router to a smart outlet and schedule daily reboots without losing the Homekit connection. When I’m done, I’ll add all the AirPlay printers and devices to the 5 ghz band.
