Product information

Description

Homematic IP HmIP‑STH‑A is a freestanding indoor temperature and humidity sensor designed for continuous room climate monitoring. The device measures ambient temperature and relative humidity and transmits readings wirelessly to a Homematic IP access point or compatible system. Powered by a single LR03/AAA 1.5 V alkaline battery, it offers compact dimensions (86×86×20 mm) that allow flexible placement on tables, shelves or other flat surfaces. CE certified, this sensor supports smart home climate control by providing reliable environmental data for automated heating and ventilation actions.

Advantages

The sensor provides precise temperature and humidity measurements within defined ranges, enabling integration with radiator thermostats, underfloor heating actuators and the Homematic IP app. Wireless operation and compact size simplify installation and repositioning without wiring. Battery power ensures operation during power outages and allows placement where mains power is not available. The device supplies actionable information that can trigger ventilation recommendations or climate control adjustments to reduce the risk of mould formation.

Suitable for

  • Monitoring room climate in living rooms, bedrooms and bathrooms
  • Climate control together with Homematic IP thermostats and actuators
  • Detecting elevated humidity levels near laundry areas, dryers or washing machines
  • Integration into smart home automations for ventilation and heating

Key specifications

  • Form factor: freestanding indoor sensor, compact housing 86×86×20 mm
  • Power supply: one LR03 / AAA 1.5 V alkaline battery
  • Temperature measuring range: 5 °C to 60 °C
  • Humidity measuring range: 20 % to 80 % relative humidity
  • Wireless communication: compatible with Homematic IP systems (wireless protocol)
  • Installation: no wiring required, place on flat surfaces
  • Certification: CE

How to use

Insert one LR03/AAA 1.5 V alkaline battery, place the sensor on a stable, flat surface and register it in the Homematic IP app or compatible central unit following the manufacturer's pairing procedure. Position the sensor away from direct heat sources, drafts and windows to ensure representative ambient readings. After pairing, configure the device within the app to share temperature and humidity data with radiator thermostats, heating actuators or automation routines. The system will then use sensor data to adjust temperature setpoints or issue ventilation recommendations when humidity levels exceed predefined thresholds.

Usage recommendations

For reliable measurements, position the sensor at typical room height on a shelf or table at least 0.5 m away from heat sources and wet areas. Replace the battery when indicated by the app or before measurement accuracy degrades. Use the sensor in combination with Homematic IP climate devices to implement automated ventilation or heating strategies that help minimise mould risk and maintain comfortable indoor conditions.
