Ecovent Smart Vent System vs Shelly Plug S Gen3

The Ecovent Smart Vent System is a German‑engineered exhaust solution that automatically adjusts fan speed based on real‑time humidity, temperature and odor sensors. It integrates with popular smart‑home platforms, allowing remote control and scheduling via a dedicated mobile app. Designed for kitchens, bathrooms and laundry rooms, the system provides quiet, energy‑efficient extraction while preventing mold and excess moisture. Installation is modular, supporting both new builds and retrofits, and the sleek design blends seamlessly with modern interiors.

The Plug S Gen3 is the third generation of Shelly's compact smart plug, and unlike most plugs in this price bracket it includes power monitoring as standard rather than as a step-up feature. That makes it genuinely useful for finding which appliances are driving a bill, not just for switching things on and off remotely. It combines Wi-Fi with Bluetooth, supports schedules and automation, and works with Home Assistant, Amazon Alexa, Google Home and Apple HomeKit, plus Matter on the MTR variant. That breadth is the reason Shelly has a following among people who want local control rather than cloud dependence. Shelly sells an unusually deep catalogue around it, spanning relays, energy meters, sensors, thermostats, wall displays and smart locks across Wi-Fi, Zigbee, Z-Wave, LAN and KNXnet/IP.
