SMART THERMOMETER HYGROMETER

WiFi Thermometer Hygrometer Sensor with External Probe: Take Command of Your Indoor Grow Climate

At BloomLED, indoor growing specialists for more than 10 years, we give the same advice every time: a premium LED grow light only delivers its full potential inside a climate you actually control. This Domiz WiFi thermometer hygrometer tracks temperature, humidity and light levels around the clock, and streams every reading straight to your phone.

WiFi thermometer hygrometer sensor with external probe from BloomLED

Forget the once-a-day glance at a dial whenever you happen to walk past the grow tent. Connected over 2.4 GHz WiFi to your home router, this sensor pushes its readings into the Tuya Smart and Smart Life apps, where a full history builds up hour by hour. You read the curves, spot the late-afternoon heat spikes and finally understand why your plants stall at one specific point in the cycle.

The external probe is what sets this unit apart. It lets you measure where the data genuinely matters: at canopy height, directly under the grow light, inside a sealed propagator or within a small greenhouse. The display unit stays where you can read it while the probe sits in the middle of the foliage. Noticed a small offset against another instrument? Manual calibration from the app brings it back in line in seconds.

Compatible with Alexa and Google Assistant, the sensor also becomes the brain of your automation setup. Paired with Tuya smart plugs it can spin up an extractor fan above a temperature threshold, shut down a humidifier once flowering-stage humidity is exceeded, or push an alert notification before stress sets in. USB power with a backup battery keeps the log running even through a mains outage.

10+Years of expertise

🌱 A climate that never drifts unnoticed

Temperature, humidity and light logged continuously, with nothing for you to do. You keep control of the three parameters that drive vigour in veg and yield in flower.

📱 Full remote monitoring from your phone

Tuya Smart and Smart Life display live values, history and trend curves. Away for the weekend or stuck at the office, your indoor garden stays in plain sight.

🔌 Automation across the Tuya ecosystem

Build scenes with your smart plugs: an extractor that ramps up past 28 °C, a humidifier that cuts out at the right threshold, an alert that reaches you before things go wrong.

🎯 External probe for readings you can trust

Place the remote probe at canopy level, inside a propagator or in a small greenhouse. You measure the climate your plants actually experience, not the one in the hallway.

🔋 USB power with backup battery

Plug it into any USB charger and it runs indefinitely. The backup battery takes over during a power cut, so your measurement history never has a gap in it.

Can the external probe stay permanently inside a humid grow room?

Yes. The remote probe is built for continuous use in an indoor growing environment, including high-humidity flowering conditions. We simply recommend never submerging it and keeping it clear of the direct output of a humidifier or fogger, so condensation cannot settle on the sensing element and skew your readings.

Do I need a 5 GHz WiFi network to connect the sensor?

No — quite the opposite. This sensor works on 2.4 GHz WiFi only, a band that passes through grow tent walls far better and reaches much further than a 5 GHz signal. If your router broadcasts both bands under a single network name, temporarily disable the 5 GHz band while you pair the device in the Tuya Smart app.

Can the sensor switch my extractor fan on automatically?

It can, as soon as your extractor is plugged into a Tuya or Smart Life compatible smart plug. In the app you create a scene along the lines of "if temperature rises above 28 °C, then switch the plug on". The sensor does not switch mains power itself: it supplies the reading that triggers the action. That is the foundation of a reliable automated indoor grow.

Does the light reading let me check my LED grow light?

It gives you a very useful relative indication: at a glance you confirm the day/night cycle is running as programmed, that the timer has not dropped out and that intensity stays stable week after week. It is not a quantum meter though — measuring PPFD in µmol/m²/s and mapping real PAR under your grow light calls for a dedicated instrument. The BloomLED team can point you to the right one for your footprint.

A sensor that costs less than €40 and saves a harvest from three too-humid nights is, quite simply, the best safety-per-euro upgrade in your grow space.
