3-Channel Wireless Thermometer

The OBET B66-Multi monitors temperature and humidity across three separate locations from a single colour display. It ships with three wireless sensors and offers a transmission range of up to 500 feet. The base unit shows current readings, daily high and low records, trend arrows and a 12-hour forecast based on barometric pressure.

Homeowners needing multi-room visibility

This unit suits anyone who wants simultaneous indoor, outdoor and auxiliary readings such as a fridge, garage or greenhouse. Buyers who require data logging, smartphone alerts or integration with a smart-home hub should look at a different product because this model provides only local display and audible alarms.

Three sensors and 500-foot range

The system comfortably covers a typical house, garden and outbuilding with one sensor each. Accuracy is stated as plus or minus 1.8 degrees Fahrenheit for temperature and plus or minus five percent for humidity. Range and reliability will decrease through thick walls or metal structures, and the display backlight stays on only when USB power is connected.

Questions about this item

What power source must I provide for the base unit to keep the backlight on continuously?

The base unit needs a USB power adapter to run the adjustable backlight on high, low or off settings; on batteries alone the backlight turns off after 10 seconds.

Can the three wireless sensors transmit through walls to a garage 500 ft away from the display?

The sensors are rated for 500 ft line of sight; walls and interference will reduce the reliable range, so test placement before final mounting.

How do I confirm the frost alert is active on the 7.68" colour display after setup?

When the outdoor temperature reaches 33.830.2 °F the frost and snowflake icons flash, and the snowflake stays lit below 30.2 °F, showing the alert is working.
