A home on Sydney's Northshore, commissioned in stages and instrumented by Casient since July 2025. It has run daily for fourteen months, and Casient is in beta as a product. Casient publishes the numbers that flatter it and the ones that do not, because a system asking for this much room in someone's home owes them the receipts.
Actions the owner reversed within ten minutes. The only number that measures whether the house was right about what somebody wanted. It goes up when the product is wrong, so it started badly, and Casient says so.
Caveat Computed from Casient’s own logs.
Reduction in scene buttons and app interactions per day, against the eight weeks before commissioning.
Caveat Eight weeks, not a year. Seasonal effects are not fully excluded.
Unit availability. Two outages, both power, both recovered without intervention.
Caveat Computed from Casient’s own logs.
Same tariff and season. Driven by moving loads into the solar peak, not by using less.
Caveat Cannot control for a household that also became more conscious of its use.
One home, one KNX system, one Keystone.
Casient would rather publish this list than have you assemble it yourself during a sales conversation. If any of it rules Casient out for your house, that is the right outcome.
The next houses will be other people's. That is when this page becomes worth something.
