If you haven’t used the compatibility checker now would be a good time to see if you need EZWire too.

HōlHōm (pronounced whole home) is more than a smart thermostat.  It is actually a complete platform that includes a special radio that can communicate with Smart Meters using ZigBee (think of Wi-Fi for devices).  The ZigBee connection is utility grade and very secure.

You don't have a ZigBee Smart Meter?  No problem, HōlHōm+ works with non-Zig-Bee enabled smart meters and mechanical meters.  Check our guide for HōlHōm compatible meters and HōlHōm+ compatible meters.

HōlHōm’s primary purpose is to collect your energy information and help you manage it.  Since your heating and cooling is the single largest user of energy in your home HōlHōm has an advanced Smart Thermostat that will keep you comfortable while saving you money.

Is HōlHōm compatible with your furnace?  Check now with our interactive tool and find out.

System Requirements: 

  1. ZigBee-enabled Smart Meter (check here to learn more) If you don't have a ZigBee-enabled Smart Meter - HōlHōm+ is right for you.
  2. Common Wire (check here to learn more), or optional EZwire.

Optional Add-on:

  1. HōlHōm Smart Plug - you can see your energy breakdown by individual appliances. Just plug in any device like your refrigerator, home theater system, or any appliance and compare the last hour, day or month.
  2. EZwire - a unique, proven, patented (no one else has it) solution to the typical thermostat retrofit problem where the old thermostat had no need for a common wire so there is none, and are no extra wires available.
