My opinion is that the actual temperature probe should be external ie. connected to the zigbee/zwave/cloud device by cable. It should also be natively supported by ST. There is not too many such devices, if any. One choice is Fibaro Smart Implant with external sensor but that is a bit pricey and may need some custom DH etc.
My choice is diy Konnected device with temp. (and hum.) sensor. The HW is very cheap and Konnected cloud is free (hopefully forever) and it is supported by ST. The device is powered by USB power supply and only the sensor is inside… whatever. I’m using it currently in sauna (high temperatures). Next I do the freezer (low temp), then outside (high/low/wet) and maybe sometime the pool (immersed).
