Switches with the Jeweller connection protocol
Jeweller
— a proprietary Ajax protocol with long range and high robustness on sub‑GHz, built for security tasks and smart automation: communication is encrypted, status is monitored two‑way, and battery-powered devices run for years. Unlike universal standards, it requires an Ajax Hub and operates within the brand, but it excels where the priority is reliable, stable alerts along with lighting automation.No offers found
