Ability to create a watering schedule that runs if:
- Set weather criteria is forecasted (e.g. run schedule before 12pm if afternoon temp is forecasted above 100F)
- Set weather criteria is met (e.g. run schedule at 5pm if daytime temp exceeded 100F).
Use case: I’m managing a home vineyard with Rachio (117 vines, 2 zones) and am using a fixed schedule every other day and quick runs (when I remember) to give the vineyard extra water before and after a really hot day. Unfortunately, we had a lot of 100F+ days and I didn’t remember on enough of them to avoid significant heat damage (raisins). Automating the extra watering that I’m doing today via quick runs into a weather based schedule would be 100x better than relying on my memory and would save me a lot of time on manual watering.

Hey this sounds like a cool project. It’s easy to write these rules based on the forecast for rain and/or humidity with Home Assistant. There are many free forecasting integrations like AccuWeather so you can take action based on what’s forecasted today or the next few days.
Let’s say you want to take additional action at 11 am if the forecast for that day is temp over 100F. I see there’s a Rachio integration so you should be able to let HA manually control your zones and then I’d also have it send you a push notification that it ran or didn’t.
There is also no reason you couldn’t ask HA to check the temp every hour with some local temp sensor you’ve got on the property, and then if the max at any point that way was above, say 100F, turn on the zones at 5 pm for a couple of minutes of supplemental watering.
