VIIVRIA 24V AC 40VA Transformer for Wired Doorbells & Thermostats – Ring Pro/2/3/4, Nest, Ecobee compatible

Power your wired smart devices with a dedicated 24V transformer

The VIIVRIA 24V transformer provides a stable, dedicated power path for wired doorbells and low‑voltage thermostats. With a reliable 24V AC output at 40VA, this unit is designed to support devices that rely on a constant power supply, helping to minimize interruptions and chimes that flicker or drop offline. Built for real homes with multiple smart devices, it’s a practical upgrade when existing transformers underperform or struggle to supply full loads.

Designed to optimize compatibility across popular wired ecosystems, this transformer is a strong match for Ring Video Doorbell Wired, Wired Doorbell Pro (and Pro 2/4), and a wide range of thermostats including Nest, Ecobee, Honeywell, and Sensi. If you have several devices in one area—such as a doorbell plus multiple thermostats—the unit can deliver steady power without repeatedly tripping or dropping voltage. Users often notice steadier doorbell operation and more reliable thermostat performance when power demands are met by a dedicated supply.
