Vivifly Restored Home Other smart radiator thermostat valve

The Vivifly smart radiator thermostat valve, listed as Restored Home in color Other, has a touch LCD showing the current temperature, mode, on/off status, time settings and low-power indication. You can change settings on the valve; its backlight turns off after 10 seconds of inactivity. With a Tuya zigbee hub, the Smart Life app lets you control it remotely from a phone or tablet.

Voice control works with Echo Alexa, Google Home and Yandex Alice. The Open Window function pauses operation for 15 minutes when room temperature drops quickly to an adjustable threshold of 5-25; the pause can be set from 5-60 minutes. If the temperature remains below the threshold after the pause, normal operation resumes.

Open Window Mode is off by default and can be enabled on the device or in the app. Choose from 3 weekly schedule options (5+2 / 6+1 / 7), with up to 6 time periods per day. Scheduling works on the valve or in the app. Holiday, automatic and boost modes are also available.

The linkage function can use other smart home devices to create scenes for leaving home, returning home, dinner or sleep to help save energy.
