The Bluelab Wi-Fi Guardian is a continuous monitoring unit for growers who need eyes on their reservoir around the clock. It measures pH, EC/conductivity, and temperature simultaneously and pushes live data to the Bluelab Connect app — so you can track trends, get alerts, and act before a drift becomes a problem, whether you are standing in the grow room or not.
Specifications
- Calibrate your pH probe weekly using Bluelab pH 4.0 and 7.0 solutions — a calibrated probe is the difference between reliable data and guessing.
- Set your app alerts to trigger 0.3 pH units outside your target range so you get early warning without constant phone-checking.
- Store the probe tip in Bluelab KCl probe storage solution when not submerged — a dry probe degrades fast.

Frequently Asked Questions
Does the Wi-Fi Guardian work with 5 GHz Wi-Fi?
No. The Wi-Fi Guardian operates on 2.4 GHz networks only. Make sure your router has a 2.4 GHz band active and connect to that band during setup.
Can I monitor multiple grow rooms from one Bluelab Connect account?
Yes. The Bluelab Connect app supports multiple devices under a single account, making it easy to manage several reservoirs or grow spaces from one dashboard.
Does it keep working if my internet goes down?
No — remote alerts, logging, and app access all require an active internet connection. The unit will continue displaying live readings locally if Wi-Fi drops, but cloud functions pause until connectivity is restored.
How long does the pH probe last?
With regular calibration and proper storage in KCl probe care solution, Bluelab probes typically last 12–18 months. Replacement probes are available separately and use a standard BNC connection.
Is the Bluelab Connect app free?
Yes. The Bluelab Connect app is free to download and use. There is no subscription required to access monitoring, alerts, or data logging features.
