Looking for HomeKit enabled temperature sensor to trigger automation at a set temp

I bought HomeKit compatible outdoor shades but would prefer to have the shades go down over the windows when a certain temperature is sensed rather than simply using a timer. Some days are cloudy and some are cool so I don't want the shades to come down on those days but if I can have them go down when a set temperature is sensed, that would be what I'm looking for. When the sun hits that side of the house, it gets pretty hot and I'd set the trigger temp accordingly. The sensor would be located outdoors near the shades so it needs to be waterproof. Anyone know of any?
