Cullins UT20: Complete Smart Home Hub Guide for 2026
Smart homes are growing more popular every year, but they can be tricky to manage. Different devices often use different wireless standards. Lights, locks, cameras, and thermostats may not communicate well with each other.
That’s where the Cullins UT20 comes in. This universal smart home hub connects multiple devices across brands and protocols, simplifying your smart home experience. Whether you’re starting fresh or upgrading, it can unify your entire ecosystem.
