This thing has given me trouble from the get-go! I have the b-hyve time along with the hose timer. Any money that was poten tioally saved bny using this system is clearly out the window with all the times I have found the unit failed to shut off the last group on sprinklers and they just ran and ran and ran. The unit constantly locks up and fails to do anything until you open it up and yank the ribbon cable and plug it back in. There is no warning when this will happen, the only sign is a near-dead lawn because the timer failed. Have there been any upgrades to the system to correct these errors (I have seen other complaints same issues)? I like the concept and would consider giving it another go if the system works smoothly now. Any trade-in credit towards a working system?
