7 months ago thanks - so the first question is: how much time was between this calculation and the previous? Since the ET per day is really per 24 hours, so have introduced a capability to reduce the results by a certain factor depending on how many hours were between the first and the last data point collected on which we did the calculation. If that is indeed the cause of the reduction then I think the time elapsed before this calculation was about 9 hours. Is that correct?
Alternatively, is it just the rain amount that is not correct? Are all other values the same as you expected? If so can you try to set the aggregation for precip to something else and then to Last again to see if that changes anything? Please render another diag file after the change.

What happened?
The integration takes into account incorrect rain values from the weather station. I checked data from the calculate_et_for_day function. I noticed that it took the precip value as 1.4895833333333333, even though my sensor (set to last) was reading 3.8mm that day. I have the forecast days set to 0, so it seems to me that the actual rainfall should be directly taken into account when calculating eto. Based on the number of decimal places, it looks like it may be an average, not the last value. config_entry-smart_irrigation-f2f59f4233cca0fb6e63c993212765fb.json.txt
How to reproduce
Werify the calculated eto, precip and delta on a day when there was rainfall.
