@illbigwill03 @franz - though I had tested this feature as it was being introduced, today was my first real use of it with my irrigation maintenance company. They came to winterize my system.
They booked a bit of extra time with me today as they knew I had a new controller (IRO) and they have an interest in seeing how it worked. I first walked them through all the granular controls it has for the zones, head types, soil types, slope, etc. I showed them how the seasonal adjustments work.
I then created a temporary account and sent them the email. They received it on their smartphone. I showed them how to select each zone and set a duration. I like that the duration stuck as they changed zones as they let it run for 4 minutes per zone. Everything worked as expected and they were quite impressed. They are Hunter resellers and they can start to see the benefits of network connected system.
