## Overview

The Bluelab Guardian Monitor Wi-Fi is a cutting-edge, wall-mountable device that provides real-time monitoring of pH, conductivity, and temperature in nutrient reservoirs. Featuring built-in Wi-Fi and seamless Edenic app integration, it delivers instant alerts and historical data to your smartphone, empowering growers to optimize plant health remotely. With multi-scale measurement options, replaceable pH probes, and plant-safe design, it’s engineered for precision, convenience, and global compatibility.

## Description

Your key growing parameters - at a glance, anywhere, any time. In just one glance the Bluelab Guardian Monitor Wi-Fi conveys all 3 critical parameters for successful growth: pH, conductivity, and temperature. With built-in Wi-Fi capability, if enabled the Bluelab Guardian Monitor Wi-Fi can display data in Edenic (an online software platform, visit Edenic.io for more information). Allowing growers to keep an eye on nutrient levels from anywhere, at any time. Capable of displaying conductivity in EC/CF, TDS (ppm 500) & ppm 700 scales and temperature in °C or °F. The Bluelab Guardian Monitor is a constant indicator of the desired levels of nutrient solution, enabling growers to optimize parameters as crops progress through each growing stage. The Bluelab Guardian Monitor Wi-Fi is mainly powered and mounted to the wall or hung on support with two probes placed into your reservoir. The Bluelab Guardian Monitor Wi-Fi gives you mobile alerts in Edenic software. You will be the first to know if something goes wrong in your nutrient reservoir. Two-way communication means you can update alarm settings from the comfort of your armchair, all adding to that peace of mind that your plants are well guarded.

Review: I only read negative reviews to gather my opinions on a product. If you're serious about buying a product like this, consider that pH probes are not a lifetime investment due to their nature, and move on with life. This unit has a permanently fixed EC sensor, and a replaceable pH sensor. I've purchased two of these units. The first came out of the box and required no calibration as far as I could tell. The second unit came with a defective pH probe (again reference why these probes are problematic in general regardless of manufacturer)... Immediate and awesome response from Bluelab support and they are sending me a replacement probe with no issues. The reviews I've read about this company are consistent with my experience, and I cannot recommend them more. If you want to integrate your own app with their API, it's braindead simple. I cannot recommend this product more.
Review: Der Bluelab Guardian Monitor ist schlichtweg ein Gamechanger! Von dem Moment an, in dem ich ihn in Betrieb genommen habe, war ich beeindruckt. Die Einrichtung? Kinderleicht! Selbst ohne tiefgreifende technische Kenntnisse ist die Bedienung intuitiv und selbsterklärend. Innerhalb weniger Minuten hatte ich alle wichtigen Parameter im Blick. Und was soll ich sagen? Die Performance ist einfach überragend. Die kontinuierliche Überwachung von pH-Wert, Leitfähigkeit (EC) und Temperatur gibt mir ein unglaubliches Gefühl der Kontrolle über meine Anbauumgebung. Endlich kann ich Schwankungen frühzeitig erkennen und sofort reagieren, bevor sie meinen Pflanzen schaden. Die präzisen Messwerte geben mir das Vertrauen, dass meine Nährstofflösungen und Umgebungsbedingungen optimal sind – und das sehe ich auch an meinen gesunden und kräftigen Pflanzen! Die Benutzeroberfläche ist klar und übersichtlich gestaltet. Die großen, gut lesbaren Anzeigen ermöglichen es mir, die Werte auch aus der Entfernung problemlos zu erfassen. Die Möglichkeit, Alarme für kritische Bereiche einzustellen, ist ein weiteres unschätzbares Feature, das mir viel Zeit und Sorgen erspart. Kurz gesagt: Der Bluelab Guardian Monitor ist nicht nur ein Messgerät, er ist ein unverzichtbarer Partner für jeden ernsthaften Gärtner. Er ist super gut in seiner Leistung, die Bedienung ist denkbar einfach und das Ergebnis ist schlichtweg überragend. Wenn du auf der Suche nach einem zuverlässigen und benutzerfreundlichen Monitor bist, der dir hilft, deine Anbauergebnisse auf die nächste Stufe zu heben, dann ist der Bluelab Guardian Monitor die absolut richtige Wahl! Ich kann ihn nur wärmstens empfehlen!
