I've been using a couple of GoControl WA00Z-1 Z-Wave Scene-Controller Wall Switches, each mounted outdoors, protected in a low-profile switch outlet cover like https://www.amazon.com/Taymac-MM110C-Weatherproof-Outdoor-Receptacle/dp/B001JEPX3U/ref=psdc_6291367011_t5_B07MDV7LCN. The outlet cover is surface mounted to an exterior wall, with the Zwave switch inside.
The GoControl switch is nice because it take 2x 2450 batteries, meaning that I change them less than once a year.
Despite rain, snow, winter nights in the single digits, days over 100F, and the doubts of some folks here, the switches are still working fine since 2019.
