@essentia if you leave the smart watering option turned on in the device detail page, then the automatic rain delays will continue. As far as the firmware goes, these are updated automatically on all timers that are not the Bluetooth only model. I can force an update to the timer, I will just need the MAC ID.
@einstein the smart watering in the device details page is for the entire unit, as well as the automatic rain delays. If you turn this off, it will turn off the smart watering for all of the zones as well. The smart watering option in the zones page is for that particular zone only.
