- Shelly could expand Schneider’s reach in smaller building-automation projects
- The initial opportunity is in homes and retrofits, not core factory control
- Open interfaces, integration and ownership costs will determine its impact
Schneider Electric’s planned acquisition of Shelly could help it win smaller, installer-led building-automation projects—not immediately displace Siemens at the heart of an automated factory. Analysts told FNTV that the near-term opportunity is in homes, retrofits and light-commercial buildings, where Shelly’s low-cost, open platform could broaden Schneider’s reach.
“The flanking element is there, but it starts in homes, retrofits and small commercial buildings. It's not in the core of an automated factory,” AvidThink principal analyst Roy Chua told FNTV. “Schneider gains a lower-cost digital edge that can meter and control many more loads and then feeds that data into broader energy-management workflows.”
Schneider has announced plans to buy Shelly Group, a Bulgarian smart-device company, in an all-cash deal valued at approximately $1.4 billion (€1.2 billion). The proposed acquisition would give Schneider a platform for simpler automation applications.
“Shelly gives Schneider a low-cost, open and highly interoperable IoT platform that strengthens its position against Siemens and other incumbents, particularly in smaller-scale building automation,” said Asad Khan, 5G research director at SNS Telecom & IT.
The acquisition could put pressure on Siemens and other incumbents over time, Chua said. “But in the near term the more direct competitive overlap is with Legrand, ABB, and other connected-building providers,” he said.
Khan also cautioned against treating Shelly as an immediate challenger to established industrial control systems. “We don't see Shelly's devices directly replacing industrial PLCs and other mission-critical automation systems,” he said.
The cost advantage has to survive integration
Khan said Schneider could gain business in mid-market and small-commercial automation, including from Siemens, by lowering the total cost of ownership (TCO). “Potentially, yes,” he said. “Siemens is already targeting this segment with offerings such as Desigo Plug and Play, but Shelly could give Schneider an advantage on TCO.”
“Acquiring Shelly gives Schneider a credible shot,” Chua said. “But TCO includes more than just cheap hardware. It includes things like labor, commissioning, integration and ongoing operations.”
Shelly’s devices can be installed into existing wiring without major renovation, and a large installer base already knows the tools. “To win against Siemens, it still has to execute and maintain Shelly's current strengths,” Chua said.
That means keeping Shelly’s API and local controls open, continuing to attract its community and integrating it into Schneider’s installer channel without making the products more expensive or complex. Schneider also needs enterprise-grade security and lifecycle management for use beyond homes and small businesses.
“Traditional industrial automation has much more stringent requirements. A Wi-Fi or wired relay lacks deterministic control, functional-safety certification, industrial protocol depth, cyber-resilience, and hardened lifecycle support,” Chua said. “Nevertheless, it can disrupt at the margins - the lower edge of building and light-commercial automation, complementing industrial systems at non-critical endpoints. It's not ready to displace PLCs and established control platforms.”
“Siemens won't be easily displaced in places where it's embedded with system integrators,” Chua said. “A more likely outcome is that Schneider takes share in today's fragmented, installer-led projects that Siemens isn't serving well today.”
Keeping Shelly open
Shelly co-founder Dimitar Dimitrov has told existing users that the company’s approach will not change with the acquisition. “The interest is in the community, the open approach, the speed and the products you already know,” Dimitrov posted on the Shelly support group’s Facebook page. “Changing that would make no sense for anyone — least of all for a partner who values exactly these things.”
“Schneider needs to be careful and not turn Shelly into a walled garden,” Chua said.
The proposed takeover has not closed. It is expected to close in the first quarter of 2027.
