Our Promise

Supported for the life of your home.

Most smart thermostats come with an unspoken expiry date. When the manufacturer decides to move on, they shut down the cloud service — and your working, perfectly functional device becomes a paperweight. We think that's wrong.

What usually happens

Smart home devices depend on manufacturer-run cloud servers to function. When a company is acquired, pivots, or simply decides a product line is no longer profitable, they issue a "sunset" notice — typically 12 months' warning — and then the servers go dark. Your hardware still works. The software never will again.

This has already happened to millions of households. It will keep happening.

SERA's commitment

We built SERA with a different model. Our cloud service is a core part of the product — not a cost centre to be switched off. Here's what we commit to:

  • No sunset dates. We will not end cloud support for SERA thermostats on any fixed schedule. If we ever face a situation where continuity is at risk, we will give customers maximum notice and work to transfer ownership of the service rather than shut it down.
  • Local fallback. SERA thermostats retain full schedule-based operation even without a cloud connection. Your home keeps running even if the internet goes down or — in the worst case — our servers are unreachable.
  • Open exit. Your settings, schedule, and historical data are always exportable. You are never locked in.

Why we can make this promise

We're an independent company without external pressure to cut costs or pivot to a new product line. SERA is not a loss-leader bundled with a subscription service or a data harvesting play. It is the product. That means our incentives are aligned with yours: we succeed when your thermostat keeps working reliably for decades.

We also keep our infrastructure costs proportionate to revenue, which means the service doesn't depend on continuous growth to stay alive.

Holding us to it

Promises are only worth something if they're verifiable. Our commitment is published here and in our Terms of Service. If we ever consider a change, existing customers will receive written notice at least 24 months in advance — enough time to make an informed decision.
