LSS252331 Schneider ENOcean Wireless Temp Humidity Sensor 868MHz Solar
The Schneider Electric LSS252331 is a wireless room temperature and humidity sensor from the EcoStruxure Building Expert ENOcean platform. Operating on the self-powered ENOcean radio protocol at 868.3 MHz, it harvests energy from ambient light via a solar cell and an integrated backup battery, eliminating the need for power wiring entirely. It wirelessly transmits high-accuracy temperature (0–40°C, ±0.4°C) and humidity (0–100%, ±3%) readings to compatible ENOcean receivers and building automation controllers, enabling truly cable-free room sensing.
Its compact square form factor (84 × 84 × 25 mm) in pure white RAL 9010 ABS housing mounts directly to any flat surface with minimal disruption to existing finishes — ideal for refurbishment projects where chasing cables is not acceptable.
Discontinued September 30, 2023; after-sales service continues until end of life.

Applications
Widely used in EcoStruxure Building Expert deployments in small commercial buildings across Europe, where the 868 MHz ENOcean band is the dominant wireless building automation frequency
Ideal for heritage buildings and historic properties where drilling for cable routes is prohibited or prohibitively expensive
Perfect for open-plan offices undergoing HVAC rezoning, allowing deployment and repositioning as zone boundaries change without any rewiring
Provides excellent value density for small building owners managing operational budgets with dual temperature and humidity output in a single compact device
Post-discontinuation demand remains strong for existing EcoStruxure Building Expert installations requiring sensor replacement or expansion
