Need your Serial Number or MAC Address?

Where do I find my serial number?

If you contact Rachio Support for troubleshooting or Wi-Fi help, you'll need to provide your controller's serial number so we can better serve you. The location of your serial number and MAC address will depend on what generation product you own.
