Thank you for your question. You are likely still on the current firmware, which doesn’t have the Rain Sensor indicators on it. If you’d like me to upgrade you to the firmware with this on it, please provide me with the MAC ID and I can take care of that for you.
Currently our Rain Delay does not take into account the amount of Rainfall, just the chance of Rainfall. We are currently working on an update that will change how the Rain Delay works, and you will be able to change the amount required for the delay or the % of chance of rainfall. However, you still won’t be able to make it less than 24 hours, but this is something I can definitely request to our team.
