Shelly

Shelly is a European smart-home and building-automation manufacturer under Shelly Group SE (formerly Allterco). Headquartered in Sofia, Bulgaria and listed on the Frankfurt Stock Exchange (Xetra: SLYG) as well as the Bulgarian Stock Exchange, the company rebranded to Shelly Group in June 2023 and expanded its investor presence with Xetra trading in April 2024.

Its portfolio focuses on retrofit devices that add intelligence without rewiring: compact in-wall relays and dimmers (Shelly Plus/Mini), smart plugs, and professional Shelly Pro DIN-rail modules with Ethernet/LAN and Bluetooth for panels and distribution boards. Shelly also offers detailed energy metering (e.g., Shelly 3EM and Pro 3EM) and a wide range of sensors, including Plus H&T (humidity/temperature) and Motion 2, as well as climate control products such as TRV smart radiator valves and newer wall displays.
