Product information

Description

Homematic IP 155105A0 is a wireless environmental sensor designed to measure air temperature and transmit readings to a Homematic IP smart home system. The sensor is powered by a single AA battery (1.5 V) and features a compact housing with an M30×1.5 mm connector for secure mounting. With small dimensions (58×71×97 mm) it is intended for indoor monitoring, HVAC integration and general environmental measurement tasks within Homematic IP installations.

Advantages

The sensor provides reliable wireless temperature measurement compatible with Homematic IP networks, enabling remote monitoring and automated control based on measured values. Its battery operation simplifies installation where wiring is impractical, and the standardized M30×1.5 mm connector allows secure mechanical mounting in ducts, housings or fixture panels. Compact dimensions reduce installation footprint while still providing accurate ambient readings for building automation and climate control scenarios.

Suitable for

  • Indoor temperature monitoring in residential and commercial spaces
  • Integration with HVAC systems for temperature-based control
  • Placement in ducts or technical enclosures using M30×1.5 mm mounting
  • Use within Homematic IP smart home installations for automation rules

Key specifications

  • Measured parameter: air temperature
  • Power supply: 1 × AA battery (1.5 V)
  • Mounting interface: M30×1.5 mm connector
  • Housing dimensions: 58 × 71 × 97 mm
  • Wireless protocol: Homematic IP compatible

How to use

Install the sensor by attaching it via the M30×1.5 mm connector into the chosen mounting point, such as a duct or panel opening. Insert a fresh AA battery and follow Homematic IP pairing procedures in the central app or gateway to add the device to the system. Place the sensor away from direct heat sources, drafts or sunlight to ensure representative ambient temperature readings. Once paired, configure measurement intervals and automation rules in the Homematic IP interface to use the temperature data for monitoring or control tasks.

Usage recommendations

For accurate and stable measurements, replace the AA battery before voltage drops significantly and perform mounting so the sensor is exposed to the representative room air. Avoid installing the sensor directly adjacent to radiators, ventilation outlets or windows. Use the Homematic IP app to set appropriate measurement intervals and to integrate the sensor into existing automation scenarios for HVAC control and energy management.
