We have tested our product at a range of up to 262.5 feet (80 meters) in clear air. In a house or garden, there will likely be obstacles between the Hydrawise controller and your wireless access point. This means your maximum distance will be lower. Your maximum distance will vary based on a range of factors, including your wireless access point’s transmit power and the types of obstructions between your Hydrawise controller and your access point.
You can also refer to Router Range and Distance Comparison to find out the estimated range of your Wi-Fi router (depending on its network mode).
