The Homely Wireless Temperature Node is the on-system sensor that gives a Homely-controlled heat pump its real-time room temperature, humidity and light intensity readings. This listing supplies a pair of wireless Nodes, most commonly used to add a second heating zone to an existing Homely Hub installation, or to keep a spare Node on hand for larger properties. Each Node communicates wirelessly with the Homely Hub over an 868MHz radio link, so there's no need to run sensor cabling through walls or floors. Fitted correctly, additional Nodes let Homely apply independent temperature sensing per zone on the heat pump integrations that support dual-zone operation. 2 wireless Nodes included 868MHz radio link to Hub ~16 m typical range from Hub 43x43x14mm Node dimensions 25 g Node weight CR2450 replaceable battery Check Dual-Zone Support Before Fitting Homely's dual-zone control is supported on selected heat pump integrations only. Before installing a second Node for zone control, confirm the specific heat pump brand and model supports multi-zone operation in Homely's current compatibility documentation — otherwise the extra Node can be used as a like-for-like spare or relocated sensor rather than a true second zone. Key Features Fully Wireless Sensing No wires, drilling or cable runs — each Node reports to the Hub over an 868MHz radio link, typically effective within about 16m depending on walls and interference. Multi-Sensor Design Each Node measures temperature, humidity and light intensity, feeding real-time data back to the Homely Hub for accurate optimisation. Long-Life Replaceable Battery Powered by a CR2450 coin cell battery (included), which is user-replaceable without needing to remove the Node from its wall mounting. Compact, Discreet Housing At just 43 x 43 x 14mm and 25g, the matte white PC housing sits unobtrusively on a wall or shelf in any room. Dual-Zone Ready On Homely integrations that support it, a second Node allows the system to sense and manage two heating zones independently from a single Hub. Simple Adhesive or Screw Mounting Supplied with adhesive mounting pads for quick, tool-free installation, or can be screw-fixed where preferred. Specification Homely Wireless Temperature Node (per unit) Dimensions 43 x 43 x 14 mm Weight 25 g Material PC, matte white Battery CR2450 (replaceable), included Sensors Temperature, humidity, light intensity Radio communication 868MHz to Homely Hub Range from Hub Approx. 16 m, dependent on interference/obstructions Certifications CE, UKCA, RoHS compliant Kit Contents Quantity 2 x Homely Wireless Temperature Node Mounting Adhesive mounting pads included Documentation Homely installation manual included Compatibility Requires An existing Homely Hub installation (Hub not included in this listing) Single-zone use Supported on all Homely heat pump integrations Dual-zone use Supported on selected heat pump integrations only — confirm before installing as a second zone sensor Availability Europe and UK Frequently Asked Questions Does this listing include a Homely Hub?No — this listing supplies two wireless temperature Nodes only. A Homely Hub must already be installed, or purchased separately as part of a Hub + Node kit, for the Nodes to function.Can I use the second Node for a second heating zone?On selected Homely integrations, yes — a second Node allows independent temperature sensing for a second zone. Zone support varies by heat pump brand and model, so check current compatibility before planning a dual-zone installation.How far can a Node be from the Hub?Each Node communicates over an 868MHz radio link and is typically effective within about 16 metres of the Hub, though walls, floors and other interference will reduce effective range.What battery does the Node use and how long does it last?Each Node runs on a single CR2450 coin cell battery, which is included and user-replaceable. Homely does not publish a fixed battery life figure, as this depends on reporting frequency and environmental conditions.Can a spare Node be used to replace a faulty one?Yes — a Node from this pack can be used as a direct replacement for an existing Homely Node using the same pairing process described in the Homely installation manual.Does the Node need mains power?No. The Node is entirely battery-powered and communicates wirelessly, so no mains wiring or cabling is required for installation.
