Garden Data: Fyta Plant Sensors Aim to Turn Even a "Brown Thumb" Green / Hands-On Review

 


 

“It is often said that a green thumb is something you are born with. In reality, however, that talent is likely more of a blend of knowledge, experience, and intuition. For as beautiful as plants are, they can be divas. One might prefer dry conditions, while another requires a tropical climate. Some love the sun; others get stressed just sitting by a window. Too much water causes roots to rot; too little leaves everything limp. Mistakes happen quickly, even for experienced gardeners. Yet plants often give very little warning when something is amiss.

 

This is where Fyta steps in. The Berlin-based startup aims to build a vast plant data network from which everyone can benefit. Their sensors and accompanying app are designed to make the needs of your leafy housemates visible through data—meaning you no longer have to rely solely on gut instinct or a rigid watering schedule. It sounds promising, but upon opening the packaging, we were initially left scratching our heads. The box contained several devices whose functions were not immediately obvious. A printed quick-start guide was included, but it offered little assistance. The accompanying free app was equally unhelpful at first; it felt cluttered and revealed the actual operating instructions only after navigating through several convoluted steps.

 

The proprietary Wi-Fi hub, at least, was quick to set up. It transmits sensor readings to the cloud, making them accessible anytime, from anywhere. Alternatively, the sensors can communicate directly with your smartphone via Bluetooth—though this works only within close range, which is generally sufficient for most users. The process of adding plants to the system—and subsequently pairing them with the sensors—remains consistent regardless of the connection method; it is a simple, intuitive task that goes off without a hitch. Fortunately, users don't even need to know the exact botanical name of their plant. A simple photograph is all it takes for the app to identify the correct match from a database of over 3,400 plant species. This feature works quite reliably, even though the app itself often reports a confidence level of only 30 to 60 percent for its matches. Next come the detailed questions: What type of substrate is in use? With perlite? With peat? Without? Or was it actually Akadama? This goes beyond our expertise, which is why we select "Not sure." However, the rule is: the more precise the details provided, the more accurate the analysis. The date of fertilization and the type of fertilizer used are also requested. Optionally, you can also enter the soil's pH value; Fyta offers a soil test kit for this purpose at an additional cost. If you don't know any of this either, you simply select the "uncertain" option again.

 

Finally, it comes down to pot size. This is crucial because, depending on the pot's height, you must select metal probes ranging from three to 35 centimeters, screw them into the sensor, and insert them into the soil. They should extend into the bottom third of the pot and not protrude above the rim. If the user has done everything correctly, the system begins collecting data immediately. However, the initial analysis may take up to 24 hours to complete.

 

During this process, Fyta monitors six key parameters: water levels, temperature, light exposure, nutrient levels, and humidity.

 

The catch: No indoor sensor can do it all. For instance, the manufacturer's "Beam 2" model measures everything except humidity, while other models may omit light or temperature readings. If you want to monitor a large number of potted plants and demand precise data, you may need two different sensors—which can quickly add up in cost. A single sensor costs around 40 euros, though buying them in a set works out cheaper. Incidentally, the system can also be used outdoors with the solar-powered "Terra" variant.

 

The app displays clear bar graphs that provide an overview of the plant's current condition. Furthermore, it offers care instructions and sends push notifications to your smartphone whenever immediate action is required. An extensive plant database provides information on origins, specific varieties, care requirements, and common pests—a feature that is particularly popular among hobby gardeners. Additionally, "Dr. Beamy"—a virtual assistant—can diagnose plant diseases based on three uploaded photos and offer remedial advice. Thanks to this feature, we now know with a fair degree of certainty that mealybugs have infested one of our plants, and we know exactly how to go about eradicating them.

 

In day-to-day use, however, the practical utility of Fyta is disputed. Data is delivered reliably and undoubtedly provides support. However, it does not replace the experienced eye for leaf color and growth—nor would we want it to. Especially since, in the past, our plants thrived beautifully even without technology—completely without sensors. But with plenty of intuition.” [1]
