Thermohygrometer RainPoint Rainpoint Smart+ HCS014ARF — temperature and humidity sensor, smart home compatible

The RainPoint Smart+ Thermohygrometer HCS014ARF is a compact temperature and humidity sensor for outdoor environmental monitoring and smart home integration. It measures air temperature from -40°C to 60°C and relative humidity from 1% to 99% RH, transmits readings to the Smart+ hub and mobile app via 433.92 MHz RF, and has an open-space transmission range up to 100 m. Powered by 2 × AA batteries and housed in a small, strap-equipped enclosure (130 × 47 × 24 mm), the sensor is designed for easy placement on a wall, tree, or flat surface.

Advantages

The sensor provides continuous, real‑time monitoring of outdoor temperature and humidity with remote access through the Smart+ mobile app. Stable RF communication at 433.92 MHz and a long open‑space range let you position the device freely around a garden, terrace, or building facade. Its compact, lightweight design and simple strap mounting make installation quick and flexible, while battery power avoids the need for wiring.

Suitable for

• Garden and greenhouse climate monitoring
• Smart home automation and HVAC integration
• Outdoor terraces, balconies, and façade mounting
• Monitoring conditions for plant care and irrigation decisions

When it may not be suitable

This sensor is intended for outdoor ambient air measurements and does not include built‑in heating or protection for extreme weather exposure. It may not be suitable for continuous immersion in water, for measuring soil moisture directly, or for applications requiring wired power or professional meteorological accuracy beyond the stated ranges.

Key specifications

• Temperature range: -40°C to 60°C
• Humidity range: 1%–99% RH
• RF frequency: 433.92 MHz
• Transmission range: up to 100 m (open space)
• Power: 2 × AA batteries (not included)
• Dimensions: 130 × 47 × 24 mm

How to use

Insert two AA batteries into the device, mount or place the sensor at the desired outdoor location using the strap or a flat surface, and pair it with the Smart+ hub following the hub’s pairing procedure. Once connected, the sensor will periodically send temperature and humidity readings to the hub and the Smart+ mobile app, where current values, daily minima/maxima and history graphs are available for review and automation setup.

What to consider before purchase

• Requires a Smart+ hub or compatible receiver to view data in the mobile app and enable automation.
• Operates on 433.92 MHz RF — check hub compatibility with this frequency.
• Battery operation requires periodic replacement of 2 AA cells; batteries are not included.
• Not designed for direct soil moisture measurement or prolonged water immersion.

Usage recommendations

Install the sensor in a shaded, ventilated spot away from direct heat sources and heavy rain exposure; place it within the specified open‑space range of the hub for stable communication and periodically check batteries to maintain continuous readings.
