Another step deeper in the exploration of SmartSprinkler controllers: again, the goal is to save water, time and money but not have a dead lawn or landscaping.
By focusing on the residential products, since I don’t have 24+ zones, I get down to a list of a few manufactures whose products I will choose from. Rachio, RainMachine, and Cyber Rain (residential). The Cyber Rain controller has some good functionality, but its price tag of $500 will eliminate it from further consideration since competing products are $200 or less and provide virtually the same functionality. Several municipal water systems offer rebates up to $100 for WaterSense controller, which helps lower the price, but not enough to bring $500 units back into consideration. Rachio and RainMachine both have very good reviews on Amazon, which is important as there is nothing quite like getting feedback from hundreds or thousands of existing customers. Additionally, both controllers have open APIs that allow for IFTTT (If This Then That) control and therefore access from devices like Amazon’s Echo (a.k.a. “Alexa”). Alexa is by no means a smart home controller, but until I take that leap it is nice to be able to control my devices all via voice.
It appears as though you can’t go wrong with either of these controllers. The RainMachine controller offers control from the unit itself, which could be helpful. It also has the option to not use its cloud service. However, Rachio recently released its 2nd generation controller which very clearly address feedback provided by customers. In addition, they are taking steps to ensure customers are happy with their purchase, and publicly standing behind their product will make the difference for me to give it a try. I have no doubt that even with extensive research, I may need some post sales support, and that gives Rachio at edge for me. After installation and usage, I will report back on progress.
