Wiser Energy, Home Energy Monitor, Wifi, with 1 pair of CTs

No. There is only a one-time cost for the Wiser Energy monitor. Use of the Sense Square D edition mobile and web apps is included. New features and enhancements are free via app updates and over-the-air software upgrades.

While other smart home devices are not required to use Wiser Energy in your home, they can certainly add to your experience! We currently have an IFTTT applet that allows you to connect with other devices in your home as well as skills for Amazon Alexa and Google Home. Phillips Hue, TP-Link KASA 110, TP-Link KASA HS300 (TP-Link Smart Power Strip) and Wemo Insight Smartplugs integrations are also live and the list will continue to grow!

Not everything. We're able to identify many electrical devices in typical homes and continue to expand our device detection abilities. As we examine data from more homes, the performance and coverage of our device detection will improve.

To ensure you have the best experience with Wiser Energy, the following compatibility specifications are recommended:

Your home has:

• A consistent 2.4Ghz Wi-Fi connection. Wiser Energy is not compatible with 5Ghz Wi-Fi signals.
• Its own electrical meter and accessible electrical panel.

Your mobile device runs on iOS or Android and has Bluetooth and Wi-Fi connectivity.

Your electrical panel:

• Is a split-phase 120/240V residential panel up to 200A.
• Must have enough space to fit sensor clamps with HxWxD dimensions of 3.375" x 2" x .75" (85.73 x 50.8 x 19.05mm), and an inside diameter of 1”. The Wiser Energy current sensors may not be able to fit around busbars.
• Should be within cable length of Sensor cables (46" (116.84cm) and power cable (36" (91.44cm) ).
• Does not drop below 32°F (0°C) or exceed 122°F (50°C). Is not exposed to water or areas with high condensation (Sense complies with ANSI/IEC 60529 Rated IPx0).

The following Square D electrical panels are known to be incompatible as a result of the current sensors not fitting around the bus bars:

In addition to extensive in-house testing, the Wiser Energy monitor has been tested to UL and IEC standards for safety, and certified by ETL/Intertek as safe to install in your home. Intertek is a Nationally Recognized Testing Laboratory (NRTL) and the ETL mark is functionally equivalent to the UL mark.

Wiser Energy, when properly installed, also meets all requirements laid out in the 2017 National Electrical Code (NEC). This means the Wiser Energy Monitor has been through an extensive set of industry standard safety tests to ensure that it is safe to use when plugged into electrical power and safe to use inside an electrical panel.

Per section 312.8, the Wiser Energy monitor and its current transformers are listed as a system, designed for field installation in a switch enclosure.

Wiser Energy also meets FCC Class B standards for electromagnetic interference.

All electrical devices emit electrical “noise” (in fact, the electrical noise emitted by the devices in your home is one of the things Wiser Energy uses to identify them!) — and the FCC has a strict set of limits and requires extensive testing to make sure they are not exceeded.

Wiser Energy has passed those tests and should not cause interference with other devices in your home.

• Certified to CSA STD C22.2 No. 61010-1
• Conforms to UL STD 61010-1
• Conforms to UL STD 61010-2-032
• Conforms to CAN ICES-3(B)/NMB-3(B)
• Conforms to CISPR 32
• Conforms to CISPR 35

Most likely! Your incoming solar feed can connect directly into your main electrical panel, either through a breaker or a service-side tap.

If solar is set up in a subpanel, the incoming solar feed should be within 46" of the main panel as this will allow the provided current sensor cables to reach and connect to the Wiser Energy monitor in the main electrical panel.

If it is further than 46", extension cables are available in lengths of:

These extensions can be combined to achieve larger lengths, but the maximum length can be no more than 300'.

With just two clamp-on current sensors, the Wiser Energy Monitor takes current and voltage measurements over 1 million times every second.

From this incredibly high-resolution data, it derives the electrical signatures of individual devices. In comparison, most "high resolution" smart meters only take measurements every couple of seconds... hardly real time!

Within the first week of installation, Wiser Energy should be able to find some common devices that cycle on and off frequently, like your refrigerator or microwave. Some devices will take longer to identify, until the algorithms have seen enough contextual data to reliably detect them.

There are devices that Wiser Energy won't be able to recognize right away, but as more Wiser Energy Monitors are installed across the US and Canada, the machine learning algorithms will have more data to generate models from, and the device detection capabilities will just keep growing!

The Wiser Energy monitor is intended to be installed inside new or existing Type 1 (Indoor) or Type 3R (Outdoor) 240V/120V Split-phase electrical panels.

The monitor itself is IPx0 rated and should be kept in a temperature range between 32°F (0°C) and 122°F (50°C).

We take security very seriously and we do everything we can to ensure data is secure. All communications between the Wiser Energy monitor, the cloud servers, and Wiser Energy apps are encrypted with AES 128-bit encryption and TLS/SSL (HTTPS).

Wiser Energy uses Amazon Web Services (AWS) for cloud servers and online storage. Personally identifiable information like email address and account information is stored in physically separate systems from any application data.

Physical security is managed by Amazon and access to these production systems is limited to a very small group of engineering team members.

Automated systems process the data collected from Wiser Energy monitors to detect devices, send notifications, generate report emails, and power the Wiser Energy apps.

This data is never shared with 3rd parties without explicit user opt-in on a case-by-case basis (for example, when a utility wishes to provide discounts/services to their customers in exchange for sharing limited power data.)

Support employees will on occasion need to access some of this data to troubleshoot issues, but we will only access this data with explicit permission.
