Remotely controllable via the eWeLink app, by voice command or via smart programming, \u003cstrong\u003ethe SONOFF TRVZB Zigbee smart thermostatic head regulates the temperature of each radiator independently between 4°C and 35°C\u003c\/strong\u003e.

The frost protection mode maintains a minimum temperature to protect pipes during intense cold periods, without manual intervention. Six months of data history allow analysis of consumption trends and optimization of heating schedules according to actual household habits.

Temperature calibration is manually adjustable from the app to fine-tune reading accuracy depending on the environment. Valve opening is precisely adjustable in percentage from 0 to 100% for granular management of hot water flow in the radiator, available from SONOFF ZBBridge-P, ZBBridge-U, NSPanel Pro and iHost hubs.\u003c\/p\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u0026nbsp;\u003c\/p\u003e\n\u003ch2 style=\"text-align: justify;\"\u003eExtended Zigbee 3.0 compatibility, voice commands and group management\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eCompatible with SONOFF iHost, NSPanel Pro, ZB Bridge Pro, ZBDongle-P and ZBDongle-E hubs, the TRVZB also joins Home Assistant via ZHA or Zigbee2MQTT, Amazon Echo speakers (Plus 2nd generation, Echo 4th generation, Echo Show 2nd generation) and SmartThings Hub V3. Alexa, Google Home, SmartThings, Alice and IFTTT allow setting or querying the target temperature and operating mode by voice command.

The included adapter kit covers major manufacturers. It is advisable to check your valve's threading before purchase.\u003c\/p\u003e\n\u003ch3 style=\"text-align: justify;\"\u003eDoes open window detection work without an additional door or window sensor?\u003c\/h3\u003e\n\u003cp style=\"text-align: justify;\"\u003eYes, open window detection is completely autonomous and does not require an external sensor. The TRVZB analyzes rapid temperature variations itself: a sudden drop triggers valve closure, and a rise of more than 1.5°C in 4.5 minutes triggers its automatic reopening.\u003c\/p\u003e\n\u003ch3 style=\"text-align: justify;\"\u003eCan the TRVZB be controlled without an internet connection in case of outage?\u003c\/h3\u003e\n\u003cp style=\"text-align: justify;\"\u003eLocal automation management depends on the hub used. With SONOFF ZBBridge-P\/U, NSPanel Pro or iHost hubs, local Zigbee scenes continue to function without internet. Features requiring the eWeLink cloud, such as push notifications, only work with an active connection.\u003c\/p\u003e\n\u003ch2 style=\"text-align:
