ThermoPro TP358 Bluetooth Hygrometer & Room Thermometer (Swiss-made sensor) with built-in clock, backlit display and app alerts
Product description
If you’re trying to keep indoor air conditions comfortable (especially in a baby room or greenhouse), the ThermoPro TP358 is built around one job: monitoring temperature and humidity reliably, then helping you react when things drift.
Over two units, it’s also a practical setup if you want readings in more than one room without constantly moving a single device. That said, it’s not perfect for every scenario—if your priority is purely local display without using a phone app, the Bluetooth/App side is where most of the “smart” value lives.
At a glance
The ThermoPro TP358 is a Bluetooth hygrometer and room thermometer with a backlit LCD screen, a built-in clock with date display, and a simple air comfort level indicator (DRY/COMFORT/WET). The thermometer and hygrometer reading updates every 10 seconds, so you’re not stuck waiting on slow refreshes.
On the “remote monitoring” side, you can check readings using the ThermoPro Sensor app, with a stated Bluetooth remote range of up to 80m/260ft in typical conditions (the usual caveat applies: obstacles can affect range). You can also set a temperature/humidity gauge range and receive an instant phone notification when levels fall outside your chosen bounds.
Key features that you’ll actually use
What stands out here is how the device blends day-to-day usability with phone alerts.
For everyday checking, the backlit LCD display is straightforward: it shows time and date, plus the current indoor temperature. The DRY/COMFORT/WET comfort level is designed for quick interpretation—handy if you’re trying to judge whether the air feels “too dry” or “too damp” without digging through numbers.
Then there’s the app layer. If you set acceptable ranges in the ThermoPro Sensor app, you can get a phone notification when the sensor reading moves out of that range. That’s a genuine quality-of-life feature if you’re busy, or you want to catch issues early rather than noticing them hours later.
Key specifications (what to note before buying)
- Name: ThermoPro TP358 Bluetooth Hygrometer Room Thermometer with Built-in Clock
- Type: Bluetooth hygrometer and indoor room thermometer
- Display: backlit LCD with time and date display
- Refresh rate: updates every 10 seconds
- Temperature accuracy: ±0.2°C
- Humidity accuracy: ±2%RH
Worth noting: the entry mentions a Swiss-made temperature humidity sensor, but it doesn’t explain calibration details or long-term verification—so if you’re buying for precision work, you may want to treat the stated accuracy as a target rather than a guarantee.
Where it shines (and the typical use cases)
This is the sort of sensor you buy because you want fewer surprises indoors. It’s described as useful for monitoring conditions linked to comfort and health concerns such as colds, dry skin, asthma/allergy triggers, and mould—mainly by helping you keep temperature and humidity more in check.
A very practical example: imagine you’re checking the baby room before bedtime. You glance at the DRY/COMFORT/WET indicator and the temperature reading on the backlit screen. If you’ve set a safe humidity range in the app, you’ll get a notification if humidity drops too far (or rises), which can nudge you to use a humidifier/dehumidifier or adjust ventilation sooner rather than later.
What might not suit you
The TP358 is a good fit if you’re happy to use a smartphone app for notifications and history. If you prefer a strictly standalone device, you may feel like some features (remote monitoring, alerts, historic analysis) are more effort than they’re worth.
Also, the stated Bluetooth remote range is up to 80m/260ft, but it’s explicitly tied to conditions “with no obstructions”. In a typical home with walls and floors, your real-world range may be noticeably less—so if you need reliable coverage across thick building layouts, it’s worth planning placement carefully.
Getting the most from it
To get value out of the TP358, it helps to treat it like a monitoring system rather than a one-off gadget.
First, set sensible temperature and humidity gauge ranges in the ThermoPro Sensor app based on the room you’re tracking—nurseries, offices, and greenhouses can behave quite differently.
Second, use the history option for context. The product includes up to 1 year free data storage in the app and lets you analyse past readings over time periods such as 24 hours or 1 week (and up to 1 year). That can be useful if you’re trying to spot patterns—like humidity rising at certain times, or temperature dropping overnight.
Third, consider the “2 pieces” bundle. Two units makes sense if you’re monitoring more than one space (for example, nursery plus living room) rather than buying one sensor and moving it around.
Is it worth it?
Buying verdict
You should buy the ThermoPro TP358 if you want both a backlit on-wall display (including time/date and a DRY/COMFORT/WET indicator) and app-based monitoring with range alerts. The stated comfort-level approach, fast 10-second refresh, and the combination of temperature and humidity readings make it a solid choice for everyday home management—particularly in spaces where comfort and humidity swings matter.
You may want to skip it if you only care about local readings and won’t use a phone app, or if you need guaranteed Bluetooth coverage across multiple rooms with lots of physical obstructions. It’s more of a home monitoring assistant than a lab-grade instrument, so keep expectations grounded if precision beyond the stated accuracy is your main goal.
Mini FAQ
Does the TP358 show time and date on the device?
Yes. It has a backlit LCD display with a built-in clock and date display.
How often does the reading update?
The temperature and humidity indicators are stated to update every 10 seconds.
Can it alert me if humidity or temperature goes out of range?
Yes. You can set a temperature/humidity range in the ThermoPro Sensor app and receive a phone notification if readings fall outside your selected limits.
Is there data storage for history?
The listing states free data storage up to 1 year in the ThermoPro Sensor app, with selectable time periods such as 24 hours and 1 week.
What’s the Bluetooth range?
It’s stated as up to 80m/260ft in conditions “with no obstructions”, so real-world range will depend on walls and layout.
