@Damianjoshua - I don’t think so. a) if you check the warranty page (http://www.rachio.com/warranty) you’ll see that it is a two (2) year warranty
Subject to the terms and conditions set forth herein, RACHIO warrants that the Product will be free from material defect in materials and workmanship for a period of two (2) years from the date of purchase from RACHIO or an authorized dealer
And b) I’ve seen Rachio do right by their customers.
So like @mckynzee said, contact support, reference this string and I think they’ll take care of you.
