The interior panels of Simpled Smart Locks are not waterproof, except the front panels on specific models: SS, DFF, EF, SF, RF, BF, and UF. These models are designed to handle some exposure, but for the LF/AF Leverline and CF Cylinder, it is strongly recommended to use them only on interior doors, as they are not weatherproof.
If you are considering a lock for outdoor use, it’s essential to select one of the listed waterproof front-panel models or consult an agent for suitable options.
