About This Product
Leviton's Whole Home Energy Monitor (LWHEM-2R) is the smart solution for your home's electrical system. It provides real-time energy consumption data and controls Leviton Smart Circuit Breakers. With inputs for up to 3-pairs of optional LSMMA Current Transformers (CTs) to measure energy sources, the LWHEM provides an aggregate view of your energy consumption and generation. A set of contact inputs allows integration with an Automatic Transfer Switch (ATS). When paired with Leviton 2nd Gen Smart Circuit Breakers, the LWHEM provides unparalleled control of your home's electrical system, including alerts for circuit breaker trips, notifications for unusual activity and the ability to remotely control and schedule circuit breakers.
Highlights
- Smart - wi-fi connection provides remote monitoring and control of your Leviton load center, ota firmware updates and more
- Intuitive - monitor whole-home energy consumption and production in real-time and view what power sources are powering your home
- Control - remotely control (off/on) Leviton second gen smart circuit breakers, program custom schedules for second gen smart circuit breaker activity to conserve energy and avoid running circuits when electricity is it's most expensive
- Flexible - when integrated with an automatic transfer switch and compatible backup power system, the lwhem-2r automatically sheds nonessential 2nd gen smart circuit breakers when backup power is active, preserving power for essential circuits

Questions & Answers
Does this need a dedicated circut or can it be tied into say, a 2 pole breaker that I have my Leviton surge protection on?
Thank you for your inquiry. The LWHEM-2R Whole Home Energy Monitor is designed to be powered by a dedicated 2-pole circuit breaker in the Leviton Load Center. It should not share a breaker with another device, including a surge protective device. Please refer to the installation instructions or contact Leviton Technical Services at 1-800-824-3005 for installation assistance.
Want to monitor a panel that my renters use. Will it tell me monthly kWh used
Do you have to have smart breakers? Does this still monitor whole home consumption without standard breakers?
You can use up to three LSMMA Current Transformers (CTs) to monitor specific circuits but without the smart breakers that is all you'd be able to do.
Does this require connectivity to Leviton servers or will they work off grid (local network only)? It is all too common now for vendors to quit supporting products and make them unusable or change how they are used.

Sadly, yes. Leviton has already gone through one iteration of components (the LDATA & 1st generation smart breakers) that are incompatible with the 2nd generation breakers. They also play fast and loose with their API which breaks integrations.
Unfortunately it does. If you don't need the ability to trip the breakers (or reset them) remotely, then something like the Refoss EM16P might work for you.
What size breaker should these connect to?
LWHEM-2 must be powered by on a non-smart, 2-pole breaker (surge breakers excluded). 15 or 20 amp
If I have two panels in my home (one is a subpanel), do I need two of these, or can the breakers in the subpanel communicate with the breakers in the main panel?
Two, a hub is recommended for each panel you want to install smart breakers in.
Communication between the WHEM & breakers is via Bluetooth. You'll almost certainly have to have two.
How to connect with 1 main wire, 120v only panel (jumper between two sides)?
This kind of setup is not compatible with this system and violates National Electric Code. Please contact an electrician to replace to repair this.
Since there is only one CT transformer provided, does this only provide total current for the entire panel? Do the Leviton breakers also have built in CT's to allow the measurement of current on each individual circuit?
You are correct! The CTs are for full panel view. Individual circuit levels would require those circuits have a smart breaker.
