Oh, you're right they do have a temperature sensor. Sorry, I actually only have first gen Hubs and Hub Max and I wasn't aware. I'll ask around for you to see if this sensor is accessible through assistant.
Sorry, I'm not getting anything for this. I can only advise to try a few different phrasings and if you can't get anywhere assume it's not available. Leave feedback about this in the Home app and at least your suggestion will be logged.
