Simply replace your existing radiator valve head and the device takes over, automatically adjusting hot water flow through the radiator to maintain exactly the temperature you set, down to \u00b10.1\u00b0C accuracy.<\/p>\n<p>Control is available in multiple ways: turn the physical rotating knob directly on the valve for instant manual adjustment, or manage everything remotely from the Shelly Smart Control app. A built-in rotating digital display always shows the current target temperature and lets you adjust it without reaching for your phone. Boost mode rapidly warms up a room when you need heat quickly, and weekly scheduling keeps your home comfortable while avoiding unnecessary energy use throughout the day.<\/p>\n<p>The Shelly BLU TRV connects via Bluetooth and Zigbee, and gains full Wi-Fi remote access and smart home integration when paired with the Shelly BLU Gateway Gen3 (sold separately or included in bundle packs). It also supports external temperature sensors \u2014 pair it with a Shelly BLU H&#038;T placed in the centre of the room for significantly more accurate temperature readings than the valve&#8217;s own built-in sensor, which can be affected by heat from the radiator itself.<\/p>\n<p>Two operating modes give you full flexibility: TRV mode for temperature-based automatic control, and manual valve mode where you set the valve opening percentage directly. It also supports a window-open detection function \u2014 when a compatible Shelly BLU Door\/Window sensor detects an open window, the TRV automatically reduces heating to avoid wasting energy. Powered by two standard AA batteries included in the box, with a battery life of up to 2 years.<\/p>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li>Smart TRV head \u2014 replaces existing valve head, no plumber needed<\/li>\n<li>Precise \u00b10.1\u00b0C temperature control with rotating digital display<\/li>\n<li>Bluetooth + Zigbee \u2014 Wi-Fi remote access via BLU Gateway Gen3<\/li>\n<li>External sensor support \u2014 pairs with Shelly BLU H&#038;T for room-accurate control<\/li>\n<li>Window-open detection \u2014 auto-reduces heating when window is open<\/li>\n<li>Up to 2 years battery life \u2014 powered by 2 \u00d7 AA 1.5V (included)<\/li>\n<\/ul>\n","protected":false},"featured_media":10452,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[569,983,566,575],"product_tag":[],"class_list":["post-10448","product","type-product","status-publish","has-post-thumbnail","product_cat-climate-heating","product_cat-shelly","product_cat-shop","product_cat-thermostatic-valves","desktop-align-left","tablet-align-left","mobile-align-left","ast-product-gallery-layout-first-image-large","ast-product-tabs-layout-accordion","first","instock","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Shelly BLU TRV \u2013 Smart Bluetooth Radiator Valve | Bombusmart<\/title>\n<meta name=\"description\" content=\"Smart TRV with \u00b10.1\u00b0C precision, Bluetooth &amp; Zigbee.
