## Long description

Freestanding Homematic IP HmIP-STHD-A is an indoor temperature and humidity sensor for smart home climate monitoring. It measures ambient temperature and relative humidity and is powered by a single LR03/Micro/AAA 1.5 V alkaline battery. With compact dimensions of 86×86×25 mm, the device can be placed on shelves, desks or counters to provide local climate data for automation and monitoring tasks and to support efficient control of heating and ventilation systems.
Advantages
The Homematic IP HmIP-STHD-A provides accurate temperature and humidity readings that can be used by a Homematic IP smart home system to optimise radiator thermostats or underfloor heating actuators. Its freestanding design allows flexible placement without wiring, and the low-power AAA battery operation ensures simple installation and long-term use. Integration with the Homematic IP app enables local climate monitoring and ventilation recommendations based on measured humidity levels.
Suitable for
 Monitoring indoor temperature and relative humidity in living rooms, bedrooms or bathrooms
 Providing local sensor data for smart heating control and radiator thermostats
 Detecting elevated humidity to trigger ventilation actions or notifications

Key specifications
 Device type: Freestanding indoor temperature and humidity sensor
 Power supply: 1 × LR03 / Micro / AAA 1.5 V alkaline battery
 Temperature measuring range: 5 °C to 60 °C
 Humidity measuring range: 20 % to 80 % relative humidity
 Dimensions: 86 × 86 × 25 mm

How to use
Insert a single AAA 1.5 V alkaline battery into the device according to the polarity markings and place the sensor on a stable, flat surface at the desired location. Add the sensor to your Homematic IP system following the pairing procedure in the Homematic IP app. Once paired, the sensor transmits temperature and humidity readings to the system so that automations, heating controls and ventilation recommendations can use the local climate data.
Usage recommendations
Position the sensor away from direct heat sources, drafts and direct sunlight for representative measurements. For bathroom installation, place the sensor where it measures ambient air rather than directly above shower areas to avoid localized spikes. Replace the AAA battery promptly when indicated by the app to maintain continuous monitoring.
