Looking for a weather-proof button

Hi,

I need a button which I can store outside. There is no roof there so it will be exposed to sun and rain. I have no preference on the protocol, it can be z-wave or zigbee or anything else with encryption. What can you recommend?

Haven’t found something myself.
I just bought a cheap wired opening sensor from Amazon an combined it with a Shelly wireless implant. Works well…
