Moving house, setting up a new router or changing your WiFi password? Follow the instructions relevant to your situation:
1. Moving house
If you move your router along with your lights, it should all continue working as usual. Just be sure to keep the name (SSID) and password the same.
With a new house, you might wish to update the names of your lights and groups or location.
2. New router
Pro-tip: you can set the name (SSID) and password of your new router to be the same as your old router. If you do this, all your lights will continue to work as normal. All your other connected devices should also continue to work uninterrupted, win-win.
3. Changing your Wi-Fi details (SSID or password)
If you are required to change the name and/or password, you will need to reset your lights and reconnect them, just as you did the first time you set up your lights.
Schedules and scenes will still work with the lights once reconnected. If you use the same light names, all other integrations should also work as expected.
