Most of my watering is done on a daily flex. Yesterday Rachio was saying it was going to water today (30 July) because little or no rain was anticipated. Unexpectedly in the early hours of the morning we had over 14mm (half an inch) of rain which in this part of the world is a lot and would have put the zones above field capacity. However, The moisture balance calculations showed today anticipated rain for the 30th of 0.3mm, did not reflect the actual precip and continued to schedule watering for 6.30pm. At 6.30pm I overrode Rachio as it started to water some very soggy zones. The weather station showed the correct rain data on the PWS website but Rachio did not seem to be picking it up in the current day. Here’s a screenshot of the water balance as shown at 8.00pm (by which time the forecast rain of 0.3mm had disappeared but the actual rain had still not been added to the moisture balance)
Any thoughts as to what is happening here?
