Shelly Wave H&T LR – Z-Wave Temperature & Humidity Sensor (Long Range)
Overview
Shelly Wave H&T is a compact, battery-powered Z-Wave temperature and humidity sensor designed to provide accurate, real-time environmental monitoring indoors. Built on the latest Z-Wave 800 Series platform, it supports both standard Z-Wave mesh networks and Z-Wave Long Range (ZWLR), allowing reliable direct communication with a compatible hub over extended distances.
By continuously measuring temperature and humidity, the sensor enables climate-aware automations such as controlling heating, cooling, humidifiers, dehumidifiers, or ventilation systems. This makes it suitable for improving comfort, preventing mould or dryness, and protecting temperature-sensitive spaces in homes or offices.
