Ecowitt WH51
An inexpensive wireless soil-moisture probe that stays in the bed or pot and logs moisture continuously, so you can water based on data rather than spot checks.
Not for: People who don't want to buy or run a compatible Ecowitt gateway or console, and anyone who needs pH or nutrient readings rather than moisture.

XLUX T10
Simple, battery-free soil moisture checks help guide watering more reliably than judging the soil surface alone.
Not for: Continuous outdoor monitoring, very rocky soil, or measuring pH and nutrients.
