Our take

If your heat pump is a ductless mini-split, this is the smart thermostat you actually want: it replaces the remote, adds schedules and voice control, and needs no wiring or subscription. It has to see the indoor unit, so placement matters.

What we like

  • Works with most mini-splits that use an IR remote (maker)
  • No subscription; works with Apple Home, Alexa and Google Assistant
  • 5-year warranty and 30-day trial (maker)

Watch out for

  • Needs a clear line of sight to the indoor unit
  • Plug-in only, so it needs a nearby outlet
  • Check the compatibility list first

Skip it if your heat pump is ducted and has a wall thermostat. A wired smart thermostat is the right tool.
