“Costs that are covered by the Smart Controller rebate:

Rebate covers the purchase price of one SWAT approved Smart Controller up to a maximum of $400 per address. If a landscape professional installs Smart Controller, the device and installation costs can be rebated up to a maximum of $400 (up to $200 of the $400 can be used to rebate a landscape professional’s installation fee).”
