In over 10 years I've never once had an issue with my Herpstats where I would have needed to rush home.
You get what you pay for.
They do have a Herpstat with wifi but you can only monitor the numbers, not change them. May give you what you're wanting though.

Like I said before I monitor the room temps more... Not the hotspots.
