Positioned as Shelly’s premium keyless access flagship, the Loqed Pure smart lock delivers a minimalist modern design paired with full Wi-Fi and Bluetooth connectivity, built for 100% smartphone-based keyless entry without physical keys. The bundle includes a complimentary Shelly BLU Tough ZB button for one-touch scene activation, door lock/unlock triggers, and custom home automation routines—such as automatically turning on hallway lighting when the front door unlocks after dark. Unlike competing smart locks that rely solely on Bluetooth and require constant phone proximity, Loqed Pure integrates with the broader Shelly ecosystem to sync with leak sensors, motion detectors, and PRO circuit breakers for full home security orchestration.

Its core competitive advantage over rival smart locks (August, Nuki) is seamless native integration with Shelly’s local automation stack. Even if internet connectivity drops, local Bluetooth operation retains full lock control and scene triggering, while most competitors disable remote and automated functions offline. The slim low-profile black finish fits standard European door frames without bulky external hardware, solving a common aesthetic complaint from homeowners. Users can configure temporary access codes for guests, cleaners, or contractors directly in the free Shelly app, with time-limited permission scheduling that auto-expires without manual removal.

The only minor limitation is the premium 179 EUR price point compared to budget plastic smart locks from mass-market brands, though the industrial-grade metal construction, EU safety certification, and full cross-ecosystem compatibility deliver long-term value unavailable in cheaper alternatives. For homeowners prioritizing unified smart home security and offline reliability, Loqed Pure stands as the most cohesive smart lock solution on the market.

### Deep Dive 2: Shelly PRO 1CB C16A Smart MCB (78 EUR) – Industry-Exclusive Professional Circuit Protection

The Shelly PRO CB range represents a groundbreaking innovation no competing consumer IoT brand can match: certified smart miniature circuit breakers designed for mains electrical panels, with remote on/off control, real-time voltage/current monitoring, and built-in overvoltage/undervoltage safety cutoffs. The PRO 1CB C16A single-pole model is the entry-level professional flagship, rated at 16A with a 6kA breaking capacity and full TÜV Rheinland safety certification for residential and workshop electrical installations.

Traditional standard MCBs offer zero digital monitoring or remote control; electricians must physically access the breaker panel to cut power during emergencies or extended vacations. Shelly PRO 1CB lets users remotely isolate circuits via the app, receive instant diagnostic alerts for unstable power draw, and log energy consumption per individual circuit to identify wasteful appliances. For commercial facilities, pairing multiple PRO CB units with the Modbus RS485 add-on enables integration with building management SCADA and solar EMS systems, creating a fully digitized electrical panel.

Compared to expensive industrial smart breaker systems from Schneider and ABB, Shelly PRO hardware costs a fraction of the price while retaining all core safety and monitoring functionality. DIY homeowners use the PRO 1CB to automate high-draw appliances like electric heaters, water boilers, and outdoor power tools, cutting energy waste and eliminating fire risks from unattended circuits. During internet outages, local overload protection still triggers automatically—critical safety functionality cloud-locked rival smart relays cannot replicate.

### Deep Dive 3: Shelly Flood S Gen4 (19 EUR) – Best-Selling Affordable Water Damage Prevention Sensor

Priced at just 19 EUR, the Shelly Flood Gen4 is the brand’s top-selling safety sensor, engineered with a unique large-surface triple stainless steel pad design that detects standing water across the full length of the sensor, unlike narrow single-point probes from competitors that miss slow leaks under sinks or washing machines. Powered by long-life AA batteries (included), it operates entirely wireless without hardwiring, with three configurable alarm sensitivity modes: Intense, Normal, and Economic to match different household risk levels.

The most valuable feature for homeowners is local offline automation logic: when water is detected, the sensor sends a signal to connected Shelly relays or smart water valves to shut off mains water supply instantly, even with no internet connection. Competing leak sensors only send phone alerts via cloud and lack local trigger capability, leaving homes vulnerable to flooding during broadband outages. The Gen4 model supports multi-protocol communication (Wi-Fi + Bluetooth BLU) for seamless pairing with all Shelly Gen3/Gen4 devices, and real-time push alerts arrive on the Shelly app within seconds of water contact.

For vacation property owners, rental hosts, and families with washing machines, dishwashers, or basement plumbing, this low-cost sensor delivers massive cost savings by preventing thousands of euros in water damage repairs. At under 20 EUR, it represents the most accessible, fully featured flood protection solution available on the European smart home market, with no hidden subscription fees for alert delivery.

### Deep Dive 4: Shelly BLU Motion ZB (21 EUR) – All-Round Light & Occupancy Automation Sensor

Retailing at 21 EUR, the Shelly BLU Motion ZB is a compact battery-powered PIR motion and ambient light sensor built for flexible home lighting automation, with fully adjustable detection sensitivity and configurable bind time delays to eliminate false triggers from pets or minor movement. Unlike rigid fixed-sensitivity motion sensors from Sonoff and Tuya, users tweak detection range, hold time, and light threshold values directly in the Shelly app to create hyper-specific automation rules: for example, automatically turning on bedroom lights only after dusk when motion is detected, or shutting off outdoor lighting once ambient brightness exceeds a set lux level.

All automation logic runs locally on the sensor hardware, so lighting scenes continue operating during internet blackouts—an essential advantage for hallway, stair, and bathroom lighting that relies on consistent occupancy sensing. The Bluetooth/Zigbee dual protocol design enables pairing with distant Shelly relays without additional signal extenders, cutting down on extra hardware costs for large homes. The slim form factor mounts discreetly on walls, ceilings, or cabinet frames with no visible wiring, ideal for aesthetic-focused homeowners avoiding bulky sensor hardware.

This sensor works seamlessly alongside the Loqed Pure smart lock to create entryway routines: unlock the front door via smartphone, trigger BLU Motion ZB to detect occupancy, and activate hallway lighting automatically. For commercial offices, multiple BLU Motion ZB units manage lighting energy use by powering down fixtures when spaces are unoccupied, delivering measurable monthly electricity savings for businesses.

### Cross-Line Product & Competitor Comparison to Guide New Customer Purchases

For shoppers debating between Shelly and rival smart home brands including Sonoff, Fibaro, and Aeotec, this direct comparison breaks down decisive differentiators across privacy, hardware range, pricing, and installation use cases to simplify purchasing decisions:

1. **Cloud Dependency & Data Privacy**

Sonoff and Tuya devices require mandatory cloud servers for core automation and scene logic, exposing user energy data and sensor activity to third-party platforms and creating total system failure during internet loss. Fibaro and Aeotec rely on proprietary central hubs that add hundreds of euros to upfront costs. Shelly eliminates mandatory cloud entirely; all control, safety triggers, and energy monitoring function locally on each device, with cloud access as an optional add-on only for remote off-site viewing. Privacy-focused users, vacation property owners, and commercial facility managers gain unmatched data security with Shelly’s offline-first design.

2. **Hardware Ecosystem Breadth & Professional Electrical Support**

No competitor manufactures certified smart MCB circuit breakers, flood sensors, motion detectors, smart locks, blind controllers, and energy metering relays under one unified ecosystem.
