Bluetooth Readings From Across the House
The ThermoPro TP350 is a Bluetooth thermo-hygrometer that pairs with the free ThermoPro app to show live temperature and relative humidity readings on your phone from up to 260ft away, with no wifi, account sign-up or personal data required. Checking a tent by eye misses slow humidity creep and temperature swings until they have already stressed the plants; logging both figures every 10 seconds and keeping up to two years of history lets you spot a drifting climate long before it shows in the canopy. A large backlit display and a simple comfort indicator (dry, comfort, wet) mean you can still read it at a glance without opening the app.
