How do we know when our avocado trees need water? That is the question that opens our newest reel, and it is the question behind the newest piece of kit in our grove.
We installed an Ecowitt Wi-Fi gateway and a soil moisture sensor at Patel Ranch, so we can check what is happening beneath the soil instead of guessing from the surface. You can watch the install in the reel here: Smarter Watering Starts Beneath the Surface
What we installed
The setup has two parts, and both are deliberately simple.
First is the Ecowitt Wireless Wi-Fi Gateway, model GW1100. It is a small blue hub, and in the reel we plug it in with a USB cable to a BLUETTI Elite 100 portable power station.
Second is the soil moisture sensor itself. It is a metal probe on a cable, connected to a white transmitter unit. The transmitter runs on a single AA battery, and it talks to the gateway over radio frequency, so there is no wire to run back from the tree to the hub.
To install it, we dug a hole in the leaf-covered soil beneath an avocado tree, pushed the probe deep into the ground, and secured the transmitter to a wooden stake above ground. The on-screen line in the reel says it plainly: measuring moisture right where it matters.
Why soil beats a schedule alone
We already have a Hunter Hydrawise controller, up at the top of the ranch, watering on a schedule informed by weather data. That is a good system, and we are keeping it.
But weather data is not soil data. A schedule tells you when water is supposed to run. It does not tell you what the roots are actually holding after a hot, windy day, or after a rain that looked heavier than it was.
That is the gap this sensor fills. It gives us an onsite reading from the grove itself, so the decision is not just what the forecast said. It is what the soil says, at the tree.
What the first reading showed
Right after install, the transmitter showed a moisture reading of 62%.
We are treating that as a starting point, not a verdict. One reading does not tell us whether to water or wait. What matters is watching how that number moves over time: after watering, after rain, and through hot spells. The baseline is what turns a single number into useful information.
Less guessing, smarter watering
That is the practical point, especially when we cannot be at the ranch every day.
Before deciding to water extra, or to hold off, we can now check the soil first. In Southern California, every drop counts, and watering only when the soil actually needs it is the simplest way to conserve water and keep the grove healthy.
This does not replace the Hydrawise. It sits alongside it: schedule and weather on one side, soil moisture on the other, and a wiser decision in the middle. Less guessing. Smarter watering. Healthier trees.
