Yes it does look like HASmartirrigation has undergone a revamp. I haven't had the time to read through the new API's etc. @Kolia56 has done quite a bit of work integrating these two HA components. You can find his work here. Hope this helps.

I haven't updated to HASmartirrigation V2 yet, as I use only one zone, do not calculate ET nor precipitation (I have a PWS that delivers the data) and system is in production. As far as the code related to Irrigation Unlimited is concerned, the update would be rather straightforward.
Replace
smart_irrigation.[instance]_calculate_daily_adjusted_run_time
by
Smart Irrigation: calculate_zone or Smart Irrigation: calculate_all_zones
Replace
sensor.smart_irrigation_[instance]_daily_adjusted_run_time
by
sensor.smart_irrigation_[zone_name]
Replace
smart_irrigation.smart_irrigation_id7_reset_bucket
by
Smart Irrigation: reset_bucket or Smart Irrigation: reset_all_buckets
Then you should not be very far from a working solution. Depending on the number of zones you need to calculate irrigation time, you may need to do some home work.

Hey, i am trying really hard but the hints are not helping. Does someone have a simple complete example i could start with `?
