Plan
Tap the rooms you care about and set the temperature range you want, and when — cooling or heating, any time of day. Leave the rest: the planner works out the lowest-cost way to get the whole house there, and can borrow one room's cooling or the boiler's heat for another.
Nothing planned yet
Tap a room on the plan below to say what you want it to be, and when. Add as many as you like.

Installed as an app
One-time setup per phone, so this site counts as secure and installs as a real full-screen app:
- Download the home certificate
- Open it from your notifications or Files — or go to Settings → Security → More security & privacy → Encryption & credentials → Install a certificate → CA certificate — and pick the downloaded file.
- Open the secure version of this page — the padlock should be clean.
- There, in Chrome's ⋮ menu choose Add to Home screen → Install.
The certificate is this house's own — it only vouches for this server, and installing it does nothing beyond trusting this site.
