Product description

The Leviton Series 1000 line of revenue-grade meters meets all measurement and verification based opportunities including load management and LEED rating achievement. Designed to provide a simple and effective process for accurately capturing measurements of power consumption, Series 1000 Meters are easy to specify and install for new construction and retrofits. Leviton meters utilize highly accurate current transformers for revenue-grade performance certified to ANSI standards. Competing products use current sensors that do not provide the same level of performance. Leviton offers CTs in solid and split core styles to accommodate all phases of installation and construction. Solid core CTs are ideal for new construction, when power is not live and wires can easily be threaded through the core. Split core CTs can be installed at any time without having to disconnect wire terminations, making them the optimal choice for retrofitting an existing structure. Split core CTs close securely for fast, precise installation with no need for time-consuming tie wraps and no worries about improper seating or core half separation. Both solid and split core CTs offer high quality, long term accuracy and reliability. Every Series 1000 Meter has an installer-friendly feedback feature. The red reverse phase indicator acts as an installation diagnostics tool and illuminates if a meter is improperly installed. After installation, the green duty cycle light shows that the meter is collecting the electrical consumption data at the appropriate rate. All 100 and 200 Amp solid core CTs have color-coded labels to easily identify correct line/load orientation.

• Measures kWh and peak demand (optional)
• Certified to all applicable standards of ANSI C12.1
• Equipped with both Isolated Pulse Output and RS-485 Serial Port (Modbus Native) standard for easy interface with most AMR and BAS systems
• Utilizes revenue grade 0.3 accuracy class 0.1A secondary solid core current transformers (CTs) that conform to all applicable ANSI requirements or 1-Percent accuracy split-core CTs
• Up to three sets of CTs per phase can be paralleled per meter

User questions & answers

Question:	Can the app on my wife ios phone and my android phone be simultaneously logged in to the app
Answer:	Yes it will that is what I use mine for. It gives me an AC reading right between the Grid Ready inverter and the power grid.
Question:	Does the app function when outside the home? Ie. Will I be able to see real-time data for my home while away at work
Answer:	The P4400-vp can be shipped on international orders. Great Britain and France, even the Island of St. Martin Dutch side (120VAC) and St. Maartin French side (240VAC). have significantly different power from the US. The French and Great Britain use power 240VAC "Phase/ or live leg to ground" instead of the US "live leg to live leg" for 240VAC. Even though this unit is not usable for 240volt it is cleared for international use since the unit tests on phase to ground 120VAC and this is what we use in the US. It would appear that this has to do with the way the ground (round plug) and neutral are utilized in the device.
Question:	does it sum up power usage for a period of time, like every month
Answer:	What I understand of resolution on this context is: the increment steps of the measure. A 10 resolution will measure either 0, 10, 20, 30 .... but never a number in between.
Question:	Is it truly worth 300 bucks
Answer:	Not really. If you are sure which range is best you should start high and work your way down until you get the accuracy you need.

Product features

Save Energy and Money

Understanding how much energy your home is using, when and where, empowers you to find savings. Only Sense gives you the tools to break it down.

New as of January 2021: if you're on a time-of-use rate plan, you can input your rate zones for more accurate billing and historical costs. You can even set push notifications to alert you when entering peak zones.

See what’s up. Know what’s on.

Get a view into your home you can’t get with any other energy monitor. See when the garage door opened, the television turned on, or the dryer finished its cycle.

• Machine learning device detection finds individual devices in your home over time.
• Detailed information on when and how a device is functioning.
• Integrates with Amazon Alexa, Google Assistant, Philips Hue, TP-Link Kasa HS300, and Wemo Insight smart plugs to aid in device detection and control.

Avoid Disaster

Sure, it’s convenient to know when certain devices turn on and off, but it may just save your home, too. Heavy rains? See if your sump pump is running, or running too much. Think you forgot to turn off the oven? Set an alert to inform you if it’s been on for over an hour.

The Hardware Matters

The Sense monitor was designed for the highest level of measurement accuracy and is ETL/Intertek certified for safe operation inside the electrical panel.

Install

The Sense monitor installs in your electrical panel. (We recommend you have an electrician do that.)

Read

The monitor reads the electrical current being drawn and sends the data to the cloud.

Analyze

Sense analyzes that data and sends it back through the app on your phone or desktop.

Learn

Over time, it learns what's happening in your home, detects devices, and provides information on your energy use.

Dedicated circuit monitoring

Track up to two 120V or 240V circuits. It’s the best way to track devices like your HVAC system, EV charger or variable speed pumps.

400A split-service

Whole-home monitoring for homes with split-service 400A electrical systems, more common in newer, larger homes.

Standby generators

If your power is interrupted, Sense can tell you when your back-up generator takes over and how much energy the home is using.

Solar monitoring

Solar monitoring for homes that already have Sense, but have recently added a solar power system.

User questions & answers

Question:	What size wire fits? Will 6g wire fit
Answer:	The glasses are tall and heavy. The capacity of this drinking glass is 22 oz. and the overall size is 7"x4"x3.8".
Question:	do i need dae 2030 gateway for single meter
Answer:	YES they are https://foodservice.libbey.com/Product-Repository/Iced-Tea-Glass5
Question:	Can I use this on a 30 amp RV
Answer:	So they say on the Libbey website. My experience is that this is a strong heavy glass **BUT** with rims that are prone to chipping. I bought a dozen a year ago almost exactly, and we are down to just six glasses. The rest have been thrown away with chipped rims (sharp!). This is in a two-adult household. I *think* that they get chipped in the dishwasher, but I'm not sure exactly how they chip. We start to use one... the rim is chipped. Despite this, I like them enough that I am ordering another dozen today.
Question:	I bould this meter but I don,t know how to read kwh use
Answer:	Heavy duty glass. These are great. I bought the 22 oz ones which are pretty big. I wish I had bought the 16oz ones instead but still very happy.

User questions & answers

Question:	Hi, Cost for remote metering and outside enclosure
Answer:	The Libbey 8.25-Ounce Cosmopolitan is the perfect size glass for a dessert.
Question:	Como hago para ver la demanda
Answer:	I would not bake in mine for fear of shattering or cracking. I may be inclined to try as a bain marie (water bath bake) only if I had time to "test" a single and did not care if I broke one. I believe it would work for a gentle, gradual heat increase\decrease process. So buyer beware...this is not something I have tried yet. It is thermal shock that breaks the glass. You need to warm it gradually then cool it the same way...slowly. I am certain these are made of annealed (regular) glass not tempered like Pyrex. I have even lost Pyrex to thermal shock (oven hot on cold tile countertop). So delicate gentle gradual would be your only hope.
Question:	Can I use this meter in a single phase
Answer:	you can put anything in it but they are basically white wine glasses. not real big either. red wine glasses have a wide base.
