The heart of your heating system. It's the data source for everything on your display—your whole home's temperature intelligence in one device.
Room-by-room temperature monitoring. Each pod sends real-time data so you know exactly what's happening in every zone.
Shows heating status, boost timers, zone temperatures, defrost cycles, and live performance — all at a glance on a beautiful 5″ round screen.
Instant visibility into whether your heating system is running, with live performance metrics.
See when boost is running and exactly how much time is left before your system returns to normal.
Display all your room temperatures and setpoints in a clean, easy-to-read interface.
Monitor defrost activity so you understand your heat pump's maintenance cycles.
Don't worry, it's not smoke coming out..!
Real-time efficiency metrics and system performance insights at your fingertips.
Wall-mounted simplicity. Check your heating without unlocking your phone—it's all right there.
A visual tour of Vaya Display in different modes and panels.
Displayed when the heat pump is inactive. Confirms the system is standing by and not consuming energy unnecessarily.
Shows both heating zones simultaneously for homes with dual-zone systems. Each zone's status is visible at a glance.
Shown when a manual boost is active. A clear countdown timer shows how long remains before the system automatically returns to schedule, with an option to stop early.
Appears during automatic defrost cycles. This reassures you the system is operating normally — it's not a fault, and heating will resume once the cycle completes.
Highlights when the system reports a fault. Designed to surface important information clearly, without needing to dig through an app.
Waiting for user input to activate Boost on the single heating zone.
Adjust brightness, configure settings, or perform a factory reset.
Live and daily metrics including COP, outdoor temperature, heat input/output, and visual charts of system performance.
View and manage your daily heating and hot water plans.
Adding a new schedule entry to manage heating and hot water.
System details, faults, flow/return temperatures (requires additional Cosy Hub sensor integration), and charts of flow temperature and flow control settings and expected flow temperatures. Note: When using fixed temperatures, this will show your fixed flow temperature values.
Watch Vaya Display in action. These short clips show real interface interactions and live updates.
Triggering a boost request and watching the countdown timer update in real-time.
Vaya Display showing a live defrost cycle with current zone targets.
Managing boost on multiple zones with independent timers and status tracking.
Real-time efficiency metrics and system performance updates as you view them.
Creating and modifying heating schedule entries directly on Vaya Display.
Smooth scrolling through your weekly heating schedule with touch-friendly controls.
Every Vaya Display includes access to the Vaya Metrics Dashboard in your home browser. Track performance trends, detect defrost behavior, monitor heating and hot water temperatures, and review usage patterns from iPad, laptop, or desktop.
View current COP, power input/output trends, and key live system readings in one place.
Automatically identify defrost events to make system behavior easier to understand day to day.
Compare flow, return, heating, and hot water temperatures with historical context.
Explore daily, weekly, monthly, and yearly trends through a purpose-built chart suite.
Metrics are built from processed sensor data so trends are useful, not noisy.
Use export-friendly views to take your data into your own analysis workflow.
Displays your heating breakdown over time, be that Daily, Weekly, Monthly, Yearly or throughout the Heating System. See where your energy is going, and identify opportunities for efficiency improvements.
Displays your live sensor readings, in an overview for all zones.
Create custom graphs from your sensor data to visualize trends and insights. Choose your data range, and compare different metrics to understand your system's performance in depth.
Vaya Display is actively maintained. We ship software updates to keep pace with Octopus Energy API changes and to deliver new features as they are developed, tested, and validated for real households.
We continuously monitor API behavior and adjust integrations to keep your display reliable.
Updates are packaged and validated before rollout so stability stays front and center.
From metrics improvements to UX refinements, the platform keeps evolving after purchase.
Update philosophy: maintain compatibility, then build forward.
You are buying hardware plus an actively supported software platform.
Everything you need to go from box to wall in minutes.
Just like Home Assistant, the Vaya Display is a local-first device. Once it's in your hands, we have zero visibility into your energy usage or routines.
Your heating habits are your business, not ours.
Not entirely, but it provides a better experience for the most common use case: seeing your heating status at a glance. The app gives you control and detailed settings; the Vaya Display gives you instant visibility without reaching for your phone. Think of it as a dedicated heating dashboard rather than a replacement.
No. The Vaya Display is a maker's project built by an enthusiast to solve a real problem in the Octopus Cosy community. It's not affiliated with or endorsed by Octopus Energy, but it facilitates your use of their publicly available API. We're operating transparently, with no hidden agenda - just removing friction between your household's heating control.
We actively maintain API compatibility. If Octopus changes endpoints or payload behavior, we issue software updates to keep the display aligned and stable. This maintenance approach is a core part of the product.
Yes. The Vaya Display is designed to work seamlessly with both single-zone and dual-zone Octopus Cosy Heat Pump setups. During the setup, your zone configuration is automatically detected, and the device will display the relevant zones, setpoints, and boost controls for your specific system.
Yes, it needs WiFi to fetch real-time data from Octopus Energy's API. However, there's no cloud dependency—your display connects directly to Octopus Energy. If your WiFi drops, the device will stay in its last known state and reconnect automatically when the network returns.
For out-of-the-box installs, Octopus does not expose heat pump flow or return temperatures via their API. The Cosy Hub includes four ADC inputs, one of which is used for hot water cylinder sensing.
A 10K NTC 3950 Waterproof Temperature Probe can be connected to the Cosy Hub to measure your flow or return pipes. Once installed, these readings can be displayed on your Vaya Display to show live flow and return metrics.
Note: We do not take responsibility for the installation of additional temperature sensors.
Absolutely. The Vaya Display is local-first, just like Home Assistant. Your API keys are stored on the device itself, not on our servers. We have zero visibility into your heating patterns or energy usage. The device talks directly to Octopus Energy—no middleman, no cloud, no tracking. Your heating habits are your business.
The Vaya Display will show clear visual indicators for faults (with error codes if available) and defrost cycles. You'll see exactly what's happening, when it started, and how long it's expected to last. This transparency removes the confusion around normal heat pump behaviour like defrosting and helps you spot real issues quickly.
