MOCREO LS3 Long-Range Indoor Thermometer Hygrometer — 2000 ft Range, AAA Battery-Powered, Hub Required

The MOCREO LS3 is a battery-powered long-range indoor thermometer and hygrometer that reports temperature and humidity up to 2000 ft when paired with a compatible H5Pro or H6Pro hub.

The LS3 is an add-on sensor designed to extend your MOCREO Pro hub network into distant or hard-to-reach spaces. It does not function by itself: the sensor relays readings to your MOCREO Smart App through a paired H5Pro or H6Pro hub, so you can view live values, receive alerts, and export historical data from anywhere. The device reads common indoor ranges for temperature and humidity and runs on three standard AAA batteries for flexible placement.

How far can the LS3 reliably send data?

In open, unobstructed conditions the LS3 maintains a wireless connection as far as 2000 feet from a Pro hub, making it suitable for outbuildings and distant basements. Real-world range is reduced by walls, floors, interference and metal structures, so verify the link in the app after installation.

• Maximum line-of-sight range: up to 2000 ft
• Expect reduced range through multiple walls or floors
• Confirm signal strength in the MOCREO Smart App before final mounting

What measurements and accuracy can I expect?

The LS3 reports temperature and relative humidity within typical indoor tolerances suitable for cellars, workshops, garages and greenhouses. It covers a practical indoor temperature band and measures humidity up to 80% RH; the housing is not watertight, so avoid direct exposure to water and condensation.

• Temperature range: 32°F to 140°F (approximate)
• Humidity range: up to 80% relative humidity
• Typical accuracy: about ±0.54°F for temperature and ±3% RH for humidity

Does the LS3 work by itself or need anything else?

The LS3 requires a MOCREO H5Pro or H6Pro hub to operate — it will not pair with other devices or function as a standalone unit. When linked to a Pro hub your readings appear in the MOCREO Smart App, where you can set alerts, view trend charts and export data without any subscription.

• Only compatible with H5Pro and H6Pro hubs
• Readings, alerts and charts available through the MOCREO Smart App
• Export CSV trend data for up to two years with no subscription required

How is the LS3 powered and maintained?

The sensor runs on three standard AAA batteries so you can position it where outlets are not available. Battery replacement is tool-free and a low-battery notification in the app warns you in advance so measurements continue uninterrupted.

• Power: three AAA batteries, easy to replace
• Low-battery alerts sent to the app
• Short press on the unit forces an immediate reading to the hub for signal checks

Who is this for: the LS3 is intended for homeowners, hobby growers, landlords and small-business operators who need reliable temperature and humidity monitoring in locations separated from their main living space or equipment hub — detached garages, workshops, cellars, greenhouses and remote basements. Choose the LS3 when the spot you want to monitor is far from your Pro hub; consider other MOCREO models for rooms near the hub or sealed/immersion environments like refrigerators or humidors. Remember that a compatible H5Pro or H6Pro hub is required to use this sensor.
