BaldrTherm Bluetooth Thermometer 200ft 12m Black 2pack

Pair of Indoor and Outdoor Sensors

This two-pack supplies a Bluetooth thermometer for each location you want to watch. Each unit updates its reading every 10 seconds and stores up to 12 months of history locally when the link drops. Solar-assisted power stretches battery life to 12 months, reducing maintenance. The digital display shows current conditions at a glance.

Home Owners Wanting Whole-House Coverage

Adjustable signal strength at low, mid or strong settings extends the wireless link to 200ft (60M), letting a single phone monitor multiple rooms or a garden sensor. Buyers who need wired networking or integrated smart-home hubs without a phone app should look at other platforms. The sensors operate from -20°C to 50°C, so extreme industrial environments fall outside their range.

200ft Bluetooth Range with App-Controlled Strength

The radio reaches 200ft line-of-sight and the app lets you tune the transmit power to match your layout. This single figure decides whether the sensors stay connected through walls and floors. If your longest path exceeds that distance, the link will drop and data will queue offline until reconnection.
