This product really hits on all the buzzwords. Bluetooth, smart, E-Ink—thermo, for crying out loud. Seriously, though, if you are sensitive to temperature or humidity, have a greenhouse, or you're just a tech or data nerd that wants to to track these things, this is a great deal. You get two of GoveeLife's E-Ink Bluetooth Thermo-Hygrometers which are accurate, easy to read and can be paired with other smart devices, for just $14.
