Which heating systems are compatible?
Vaya Display is designed for Octopus Cosy heat pumps, with single- or dual-zone configurations. It uses the Cosy system and sensors already linked to your Octopus account. Support for other heating systems is not currently offered.
Unsure about your specific installation? Check with us before ordering.
What do I need for setup?
A mains socket, 2.4 GHz Wi-Fi with internet access, your Octopus account number and an Octopus Developer API key. Generate the key in your Octopus account settings. Enter it only on your display, not in an email to us.
Your heat pump is normally discovered automatically. The Cosy Hub EUID is only needed if automatic discovery is unavailable.
Does it need additional sensors?
Standard use relies on your existing Cosy sensors. Optional flow and return pipe temperatures require extra sensors connected to the Cosy Hub. Those sensors and their installation are not included. Electrical work should be carried out by a qualified professional.
Is this an official Octopus Energy product?
No. It is an independent product by Chris Ambrose, compatible with the Octopus Cosy system. It is not affiliated with or endorsed by Octopus Energy.
A clear order process
From your order
to your door.
What does it cost, and when do I pay?
The current price is £260 plus UK postage. Submit your details to reserve a place in a production batch. No payment is taken at this stage, and the reservation is not a binding purchase.
We email you when the £150 deposit is due. The remaining £110 plus postage is requested before dispatch. Final pricing is confirmed before the deposit stage; you can accept or decline then.
What comes in the box?
The 5-inch round IPS touchscreen display, desk stand, wall-mounting backplate and hardware, USB-C power adapter and cable, and Getting Started Guide. Metrics Dashboard access, software updates and setup support are included. No subscription is required.
When will it be dispatched?
Your order is assigned to a production batch and receives an estimated dispatch month. Build slots are limited and depend on component availability. The date is an estimate, not a delivery guarantee.
Order updates and payment instructions are sent by email. You can also check your order status.
Where do you deliver, and what is postage?
Delivery is currently available to UK addresses only. Postage is additional to the product price and is confirmed with your order before the final payment. Your delivery address is confirmed before dispatch.
Can I change my delivery details?
Email hello@vayasystems.com with your order reference and the details to update. Contact us before dispatch.
Can I use it on a desk or mount it on a wall?
Both. The desk stand and twist-lock wall-mounting plate are included. The display needs its USB-C mains power connection; it is not a battery-powered thermostat. See the mounting and cable-routing instructions.
Does it replace my app or heating controls?
No. It works alongside your existing system. It provides a dedicated view of heating and hot water, boost controls, schedule editing and performance information. You can continue to use the Octopus app.
What happens if Wi-Fi or the internet drops?
The display shows its last-known readings and reconnects when the connection returns. Do not treat stale values as current readings. Live data and controls depend on internet access to the Octopus Energy API.
Where is my data stored?
Your API key and heating history are stored on the display. It connects directly to Octopus Energy for readings and controls; your heating data does not pass through our website. Website order data is covered separately by our privacy policy.
How do I open the Metrics Dashboard?
Find the display's local IP address in its Wi-Fi settings, then open that address in a browser on the same home network. There is nothing extra to install. History builds from when the display was first set up.
What about software updates and API changes?
Automatic updates can be enabled in the display preferences. Updates include improvements and compatibility work. Because the product relies on the Octopus Energy API, changes or restrictions to that service can affect functionality; continued access cannot be guaranteed by us.
See product updates and the terms of service for details.
Peace of mind
Help when
you need it.
What warranty is included?
Your display comes with a 12-month warranty. Keep your order reference and build note. For a problem with the display, contact us with a description of what is happening. Your statutory consumer rights are unaffected.
Can I cancel or return my order?
A reservation with no payment can be cancelled free of charge. After payment, cancellation conditions apply. The refund policy provides a 14-day return request window after delivery, subject to its conditions. Contact us before sending anything back.
Read the full refund policy and terms of service for paid-order cancellation, returns and faulty goods.
What should I do if something goes wrong?
Start with the setup and troubleshooting guide, or email us with your order reference and a description of the issue. Do not send your API key or Wi-Fi password.
If the display is reporting a heat pump fault, contact your heating installer or Octopus Energy for the heating-system issue.
