Hello,
I’d like to get data for actual precipitation in the past few hours in order to automate my irrigation.
I’m currently using the default integration from Met.no, and the hourly forecast to only irrigate my lawn if there is no upcomming rain, but I’d also like to know if there was rainfall in the last few hours.
I looked at a few APIs and couldn’t find data for actual rainfall instead of just forecasted rainfalls. Is this kind of data available anywhere (via REST) or even better, is there already an integration for home assistant that offers this kind of data?
if you’re looking for rainfall to impact your irrigation, wouldn’t it be better to have your own personal weather station (or stand alone wireless rain gauge) for that data… that way some other rain data from across the town or county isn’t affecting your irrigation needs…
I’ve got the Acurite Atlas weather station for such data… I don’t have it integrated into HA yet… I will be exploring that this weekend… there is no direct integration for my unit, and I tried the other integrations where I share my weather online and then get it back to HA through integration, but that didn’t work… there are instructions out there for using an SDR (software defined radio) to grab data from my station directly, its wireless from the weather station to its gateway device that pushes data online… an SDR can also be used to get data from smart water & gas meters if you have them… I already monitor water and energy, but I will be setting up my gas meter as well…
Well, a personal weather station would be better, but more expensive, and with a lower wife acceptance factor.
Also, there is very precicse and fine granular weather data for my area (germany), e.g. rain radar, I just can’t find a free API for it, so I was hoping there is one.
