Shelly (Allterco) – Wi-Fi Automation for Commercial Building Technology

Shelly is the product brand of Allterco Robotics, founded in Sofia, Bulgaria in 2015. The company develops compact, Wi-Fi-enabled automation modules for switching, dimming, roller shutter control and energy monitoring tasks in commercial building automation and industrial control. Shelly devices are designed for flush-mount installation (backboxes) or surface mounting, and can be controlled directly over the local Wi-Fi network without a gateway.

Shelly product families include switching actuators (Shelly 1, 2.5, Plus series), dimmer actuators (Shelly Dimmer), energy meters (Shelly EM, Pro series with three-phase metering), roller shutter controllers and temperature sensors. The Pro series (Shelly Pro 1, Pro 2PM, Pro 3EM) is specifically designed for commercial and industrial applications with higher switching currents and DIN rail mounting.

Lieske Elektronik stocks Shelly products for direct B2B procurement. Electrical contractors, system integrators and building engineers receive expert advice and volume quotes at vertrieb@industry-electronics.de.

Why Shelly?

Open protocols, local control and commercial-grade variants for professional installers

Open Integration via MQTT and REST API

Shelly devices natively support MQTT and provide a local REST API – enabling cloud-independent integration with Home Assistant, ioBroker, Node-RED, FHEM or any building management system. Ideal for system integrators delivering open, low-maintenance automation solutions.

Shelly Pro: DIN Rail for Control Cabinet Installation

The Pro series is designed for commercial control cabinet installations: DIN rail mounting, Ethernet connection, up to 16 A switching current and integrated power metering. Suitable for electrical contractors delivering standards-compliant building automation with open protocols.

Retrofit Without Construction Work

Shelly Plus modules fit into standard flush-mount backboxes and enable automation of existing electrical installations in commercial buildings without costly structural alterations – a cost-efficient solution for modernising commercial premises.

3-Phase Energy Metering for Commercial Properties

Shelly Pro 3EM measures three-phase energy up to 3×120 A – ideal for energy audits, sub-metering in commercial properties and monitoring the consumption of individual loads or floors. Data access via local API or cloud dashboard without proprietary hardware.

Frequently Asked Questions about Shelly

Answers for procurement and planning

Which Shelly products are suitable for commercial control cabinet installation? The Shelly Pro series (Pro 1, Pro 2PM, Pro 4PM) is specifically designed for DIN rail mounting in control cabinets: 16 A switching current, Ethernet + Wi-Fi, integrated power metering (on 2PM and 4PM) and local control without cloud dependency. For three-phase energy metering, the Shelly Pro 3EM (3×120 A) is the appropriate choice.

Can Shelly devices be operated without a cloud connection? Yes. All Shelly devices provide complete local control via HTTP REST API and MQTT, with no cloud connection required. The cloud can be disabled. Local automation rules can be stored directly on the device – an important factor for data-sensitive commercial properties and industrial environments.

Are Shelly devices compatible with Home Assistant and ioBroker? Shelly is natively supported by Home Assistant (official integration), ioBroker (Shelly adapter), Node-RED and FHEM. The MQTT interface enables integration with any automation platform. For commercial BMS integrations, a complete REST API documentation is available.
