That’s going to be difficult to implement because at the moment the firmware only sends one weather request each time. If every zone uses a different set of parameters that would require sending one weather request per zone, which is going to be a lot. A more feasible way would be for the weather server to send back only the weather data required for calculating the watering percentage (instead of calculating the watering percentage and return that directly). But we are hesitant to make that change because that means the weather algorithm has to be hard coded into the firmware.
