Looking to purchase a couple of whisperer sensors, and can’t really justify the $60 price. Any discount codes/discount for multiples available? Any money back guarantee if not satisfied with the whisperer?
Also, how many people are using advanced smart water feature that allow the controller totally decide when to water. I have set it up but cringe at the runtimes and days running in the calendar, and keep reverting back to my schedule. Seems like it would be using a lot more water.
