The nearest reliable weather station is a few miles away and can get radically different precipitation than I do.
At the end of the day, a local rain sensor works really well, certainly well enough and much simpler for my needs.
My zones are primarily containers on a deck and straw bales. All are fed with a 15psi drip system. I haven’t found a good way to set up containers or straw bales as soil types and a low pressure drip system as sprinkler types. The basic Orbit rain sensor seems to saturate and dry at a similar rate to my containers and bales.
It does seem that a Rain-Sensor is or should be another tool in the “Weather Intelligence” suite of tools. It gives very localized data. I suppose ideally, if you had a local PWS and a rain sensor, they would engage and disengage at about the same time. It does seem that a local rain sensor is more accurate data than a remotely located PWS or further located (and maybe more reliable) airport weather station.
