Today only, Woot offers the Rachio Second Generation 16-Zone Smart Sprinkler System Controller for $139.99 Prime shipped. If you aren’t a Prime member, delivery adds an additional $6. That’s good for a 35% discount from the going rate at Amazon, beats the all-time low there by $22 and is the lowest we’ve tracked. For comparison, our last mention was for a refurbished unit which sold for $129. Rachio’s smart sprinkler controller pairs with your smartphone over Wi-Fi to offer automated waterings based on local weather data and more. Nearly 2,600 customers have left a 4.6/5 star rating.

Rachio’s second generation controller works with Alexa and Google Assistant, as well as your smartphone. If you’d prefer HomeKit control, Rachio’s latest release sports Siri control and more from $219.
