## Long description

Homematic IP HmIP-STHO is a freestanding outdoor temperature and humidity sensor designed for environmental monitoring and smart home integration. The compact device measures ambient temperature and relative humidity and transmits readings wirelessly to Homematic IP systems. Powered by a single LR6 (1.5 V) battery and housed in a weather-resistant enclosure, it is suitable for placement on flat outdoor surfaces such as garden furniture, terraces, or sheltered ledges. Measurement ranges cover −20 to 55 °C for temperature and 0–99% for relative humidity, ensuring broad coverage for typical outdoor climates.
Advantages
The sensor provides reliable temperature and humidity data with a long wireless operating radius, enabling flexible placement without direct wiring. Its battery operation simplifies installation and relocation, while the compact housing minimizes visual impact. Compatibility with Homematic IP makes it possible to integrate the measured values into automation routines and scene controls for climate-related tasks. The device is built for outdoor use and designed to withstand common weather conditions when placed in suitable sheltered positions.

How to use
Insert a fresh LR6 (1.5 V) battery into the device according to the manufacturer's polarity markings and place the sensor on a stable, flat outdoor surface protected from direct rain and prolonged sun exposure. Pair the sensor with a Homematic IP central unit or gateway following the system's pairing procedure so the readings appear in the smart home app. Position the sensor where it can receive good wireless signal to the gateway while representing the typical conditions of the monitored area; avoid placing it too close to walls or heat sources that could skew measurements.
Usage recommendations
For accurate and durable performance, place the Homematic IP HmIP-STHO in a shaded, well-ventilated location sheltered from driving rain and direct sunlight. Replace the LR6 battery when low battery alerts appear in your Homematic IP app, and periodically check the housing for debris or insect ingress. For long wireless distances, verify signal quality during installation and consider the placement of the Homematic IP gateway or signal repeaters if needed.
