Allterco Robotics (Shelly)
Allterco Robotics, better known through its flagship Shelly brand, is a Sofia-based smart-home hardware company that designs, manufactures, and sells Wi-Fi-connected relays, sensors, and smart-plug devices that have become one of the most popular prosumer home-automation product lines in Europe. Unlike cloud-locked consumer smart-home brands, Shelly devices are designed around local control, open protocols (MQTT, REST, Matter), and compatibility with open-source home-automation stacks like Home Assistant, which has earned the company a strong following among technical users and installers who do not want their lights and shutters depending on a third-party cloud.

It is one of the most interesting examples of European consumer hardware being built out of CEE and a useful counterpoint to the region's software-heavy tech narrative.
