Popp outdoor plugs ‘popped’ into my head as candidate, but operating temperature range is -10°C to +45°C with
humidity: 10 to 95%
And they’re z-wave plugs.
About zigbee:
Zigbee is not plug & play, and not everything is compatible (when used with Homey).
For a really good zigbee controller I can recommend zigbee2mqtt for 100%
