Free open beta · Zero hardware lock-in

Independent scheduling for the hardware you already own.

Orza is free during the beta. Connect your battery in read-only Watch mode and see, on your own house, what a better plan would have saved.

Read-only Watch mode Proves the saving on your own house before anything is ever written to your battery. The beta writes nothing at all.

Nothing installed at home No hub, no Pi, no software on your network. Your manufacturer's own cloud account is the whole connection.

Zero-Hindsight Ledger Every half hour is scored against the forecast as it stood when the plan was made, never with hindsight.

Read-only Watch mode. It is the only mode on offer during the beta: Orza reads your system and scores the plan, and never writes to your battery.
