Shelly H&T Gen3 Smart Temperature & Humidity Sensor — Ivory, E‑paper Display & USB‑C

Shelly H&T Gen3 Ivory is a compact smart sensor that continuously measures temperature and humidity and reports readings over Wi‑Fi and Bluetooth with a low‑power e‑paper display and built‑in clock.

Small enough for a shelf or nursery, the Shelly H&T Gen3 Ivory pairs local sensors with cloud and local integrations so you can monitor indoor climate from a phone or automate devices when conditions change. It uses the updated Shelly chip for faster response and more memory, charges via USB‑C, and preserves battery life thanks to an e‑paper readout. The device is compatible with major voice and smart‑home platforms, making it simple to include in routines, scenes, and alerts.

How does the Shelly H&T Gen3 collect and show temperature and humidity?

The sensor uses precision internal probes to sample ambient temperature and relative humidity at regular intervals and presents readings on a low‑power e‑paper display that stays visible without draining the battery. A built‑in clock gives context to measurements, and data is stored in the device’s expanded memory for quick retrieval.

• Wi‑Fi and Bluetooth connectivity for local and remote access
• E‑paper display that preserves battery life while remaining readable
• 8MB memory on the new Shelly chip for efficient logging and responsiveness
• USB‑C port for convenient charging and firmware updates

Can I automate other devices when humidity or temperature changes?

Yes — Shelly H&T Gen3 integrates with Shelly Plus devices and major smart‑home platforms, allowing triggers and scenes when readings cross thresholds. For example, link the sensor to a wired Shelly Plus 1 to run a bathroom fan when humidity rises, or use voice platforms to query current conditions.

• Works with Alexa, Google Home, Home Assistant, Samsung SmartThings
• Create automations like fan activation based on humidity setpoints
• Use cloud or local rules depending on your privacy and latency needs
• Set alerts to notify you by phone or voice assistant when values exceed limits

How does the device fit into daily use — battery life, mounting, and portability?

The Gen3 model is designed for low power consumption, extending time between charges while offering a USB‑C charging option for convenience. Its compact footprint and clear e‑paper readout make it easy to place in a nursery, bathroom, or living room, and Bluetooth allows quick local setup and information without Wi‑Fi when needed.

• Low‑consumption e‑paper display for extended battery life
• USB‑C charging port for fast and universal power access
• Lightweight and small profile for versatile placement or travel
• Bluetooth for quick pairing and Wi‑Fi for full remote control

What integrations and support can I expect from Shelly?

Who is this for? The Shelly H&T Gen3 Ivory is aimed at homeowners, renters, and smart‑home integrators who want a compact, low‑power environmental sensor that can drive automations and provide reliable indoor climate data. It’s well suited for monitoring nurseries, bathrooms, wine cabinets, or any indoor space where keeping an eye on temperature and humidity matters — and for anyone who values integrations with popular voice assistants and home automation platforms.
