Review: ANOTHER GREAT PRODUCT FROM SONOFF - I've been using SONOFF products for a number of years now and in operation they have proved themselves to be rugged and reliable in all sorts of applications. I chose their TRV ZB valves to enable me to have an individual heating zone for each radiator. To achieve this I use the Sonoff iHost for local control and various types of Sonoff Wi-Fi switches to call for heat from the boiler (switch the boiler on or off). In essence each TRV ZB acts as a 'Master' and has a 'Slave' Sonoff Wi-Fi Switch associated with it. When the TRV ZB goes to 'Heating' status it causes its associated slave switch to fire up the boiler. The switches that I use as 'Slaves' have clean volt free contacts model 4CH PRO. It will take some time with a simple thermometer to set up these TRV ZBs to give the desired room comfort temperature level. The effort is worth it though as since installing my system I have noticed much better comfort- not too hot or too cold and seen a reduction in my heating system gas consumption and of course once set up the operation is fully automatic. The TRV ZBs come with several valve adapters but I had a couple of valves (Myson) that adapters were not available for so those valves had to be changed to a type that will take the TRV ZB. The valves are battery (3x AA) operated and very quiet in operation. They are very controllable- I'm using the SONOFF iHost with standard firmware in every device. In using these devices I've identified features that I would find desirable in future developments for the product and Sonoff/ eWelink actually encourage and listen to feedback from customers via the eWelink forum. In summary this is a very competitvly priced smart TRV that will enable DIY ers without deep coding skills to build an automated central heating system. Review: Will buy more - Purchased to replace very old manual ones because they were difficult to get to behind furniture. Have Alexa and Hive heating and these connected really well. Took a bit of time to fit, my fault as I chose the wrong adaptor piece (and because they were awkward to get at). Once I realised and got the correct one which was similar, I had no problems. They clicked onto the valve and you can hear a quiet whirring noise as it sets itself up and turns on or off. Set my routines or valve temperature in Alexa, much easier than moving furniture to alter the settings for the old manual ones. ## Features - Home Assistant Compatible: Integrates seamlessly with Home Assistant using Zigbee2MQTT, offering smart thermostat control, energy efficiency, and convenience for managing your home's heating system effortlessly. - Save Energy: The SONOFF smart radiator valve will automatically turn off when ventilating to save money and energy. It also supports 6 months of historical data queries, for daily, weekly, and monthly heating consumption views. - Smart Control: Our thermostatic radiator valve has various smart functions, including APP remote control, voice control, set schedule, group control, etc, making your life smart. Enjoy more functions of the radiator thermostat valve via the eWeLink APP, it requires a Sonoff Zigbee 3.0 hub, such as ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost, and more. - Valve Percentage Opening: The SONOFF Zigbee radiator valve supports opening ratios from 0% to 100%, with an accuracy of 1%. This design is to bring a comfortable room temperature. - Compatible with Most Valves: The SONOFF radiator thermostat fits existing β€˜M30 x 1.5mm’ radiator valves, and the valve adapters in the package are compatible with most heating systems and manufacturers. Note: TRV doesn't include 3 AA batteries. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CFY2FJW8 | | Backlight | Yes | | Best Sellers Rank | 40,837 in DIY & Tools ( See Top 100 in DIY & Tools ) 315 in Central Heating System Accessories | | Brand | SONOFF | | Brand Name | SONOFF | | Colour | White | | Connectivity Protocol | ZigBee | | Connectivity Technology | Zigbee | | Control Method | App | | Control Type | App Control | | Controller Type | Amazon Alexa, Google Assistant, IFTTT, Push Button | | Controller type | Amazon Alexa, Google Assistant, IFTTT, Push Button | | Country Of Origin | China | | Customer Reviews | 4.4 out of 5 stars 572 Reviews | | Display Type | LED | | Global Trade Identification Number | 06920075743487 | | Included Components | Manual | | Item Shape | Round | | Item Type Name | 2 | | Item Weight | 154 Grams | | Manufacturer | SONOFF | | Manufacturer Part Number | TRVZB | | Material Type | PC V0 | | Model Name | TRVZB | | Model Number | TRVZB | | Model name | TRVZB | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Packs | 2 | | Power Source | Battery Powered | | Product Style | Modern | | Special Features | Frost Protection | | Special feature | Frost Protection | | Specific Uses For Product | Heat Pump | | Specific uses for product | Heat Pump | | Specification Met | CE | | Temperature Control Type | Heating | | Unit Count | 1.0 count | | Voltage | 4.5 Volts | ## Product Details - **Brand:** SONOFF - **Colour:** White - **Connectivity technology:** Zigbee - **Controller type:** Amazon Alexa, Google Assistant, IFTTT, Push Button - **Included components:** Manual - **Model name:** TRVZB - **Power source:** Battery Powered - **Special feature:** Frost Protection - **Specific uses for product:** Heat Pump - **Temperature Control Type:** Heating ## Images ![2 Pack SONOFF Zigbee Thermostatic Radiator Valve, TRVZB, Add-On Smart Radiator Valve For Smart Home Control, Easy Installation, Save Heating Costs, Works With Alexa, Google Home - Image 1](https://m.media-amazon.com/images/I/51WOi4caM-L.jpg) ## Questions & Answers **Q: Can I connect the TRVZB heating thermostat without a gateway?** A: No, you need to pair with a SONOFF Zigbee Gateway that uses the Zigbee 3.0 protocol via the eWeLink app under a 2.4 GHz network condition, such as SONOFF NSPanel Pro, SONOFF ZB Bridge Pro, SONOFF ZB Bridge Ultra, SONOFF ihost... **Q: Not sure if the thermostat is suitable for the radiator valve in your home?** A: The TRVZB thermostat fits existing "M30 x 1.5 mm" radiator valves. Also included in the package are 6 adapters, 3 Danfoss valves (RA/RAV/RAVL), Calefi valve, Giacomini valve, thread size M28 x 1.5 mm valve. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ANOTHER GREAT PRODUCT FROM SONOFF *by E***A on 21 March 2024* I've been using SONOFF products for a number of years now and in operation they have proved themselves to be rugged and reliable in all sorts of applications.
