Yale Linus Alternative: Know It's Locked Without the Motor
The Yale Linus L2 is a proper motorised smart lock - it fits over your euro cylinder, locks and unlocks from the app, and shows lock state. It typically retails around £130-220 depending on model, and Yale's compatibility requirements mean many doors need a cylinder with an emergency function, or Yale's adjustable cylinder. If your real question is just "did I lock it?", Locksure answers it on the lock you already have, from £44.99.
Locksure monitors your lock - it shows locked or unlocked. It does not lock or unlock the door.

Locksure does none of that, on purpose. It answers one question - is the door locked? - for a fraction of the price, with no motor, no cylinder swap and no charging routine.

Common questions
Does the Yale Linus show if the door is locked?
Yes - the Yale Home app shows locked or unlocked, and DoorSense adds door open/closed. It knows the state because it is the device turning the lock. Locksure reads the same answer from your existing lock without motorising it.
Will the Yale Linus fit my door?
It fits over most euro profile cylinders, but Yale's guidance means many doors need a cylinder with an emergency/danger function or Yale's adjustable cylinder - check Yale's compatibility guide. Locksure fits beside the lock, so cylinder type is not a constraint.
Which is better for a rented home?
A monitor. Locksure attaches without changing the cylinder or the lock, which most tenancies would need permission for, and it moves with you.
