The Rachio 3e Smart Sprinkler Controller is a lesser-featured version of the Rachio 3 Smart Sprinkler Controller. It does so by stripping some functions and excluding future software features, such as Weather Intelligence Plus, Flex Daily, Yard Map, Apple HomeKit support, and integration with other, wireless devices like rain sensors and Rachio’s own Wireless Flow Meter.

 If you are looking for a less expensive, smart sprinkler controller for use at, perhaps, an investment property, then the R3e serves its purpose well. 

The unit still provides app-based, wireless remote control with historical data, weather-based irrigation, and smarts based on soil and plant types — all in a bland, gray enclosure for $80 less than the R3.
