Nuki Smart Lock Pro

Smart Lock Pro (fifth generation) Getting to the door to let a caregiver in is one of the most draining small jobs in a day. This lock fits over the existing lock on the inside of the door, with no drilling, and lets you unlock from a phone or smart home routine, or automatically as you arrive or leave. Built-in Wi-Fi gives remote access without a separate bridge, so a caregiver can be let in while you stay in bed, and the battery recharges in about two hours rather than eating cells. The limit is the door: it is made for Europrofile and selected Swiss Round cylinders, so check the fit before buying.
