The Keewi smart plugs allow users to manage power to appliances and equipment in the facility from the cloud-based intelligent analytic platform through a web portal. The Keewi smart plugs integrate with the cloud platform through the Keewi gateway, which connects to an organization’s network through Ethernet. Through cloud platform, users can enter appliance type and details each smart plug controls, toggle power supply to the smart plug outlet, create schedules, and assign schedules to an individual or a group of smart plugs. Users can monitor real-time load and trend hourly, daily, weekly, monthly, or yearly energy consumption by appliance type on the platform’s energy management dashboard. The hourly energy data for a specified period can be exported as a CSV file. In addition, the platform’s utilization dashboard also provides analytics and insights into the utilization of the appliances for each space.

Hub Highlights:

Grid Service Capabilities

What are the available functionalities that can support demand response or other grid services?

Web portal provides a toggle switch for flagging a non-critical load, and a "demand event" can be manually executed to turn off power to all non-critical loads.

Product Sales Model

Is the product purchased as a widget or a solution package? (Product sold as a widget is priced on a per-unit basis. Product sold as a solution package is priced based on the project, typically quoted by the manufacturer.)

Solution package

Installation

For a typical 1-gang duplex outlet, how would installing the smart plug impact access to the receptacles?

When plugged into the upper outlet, the lower outlet is still fully accessible. When plugged into the lower outlet, the upper outlet is obstructed.

Operation

What types of On/Off control schedules can be programmed into the smart plug through the app?

One-time schedules; Recurring schedules for day(s) of week

Operation

How many On/Off actions are allowed in each control schedule (On and Off are considered two separate actions)

Multiple; no specific limit

Operation

Can an On/Off control schedule be assigned to multiple devices, effectively group-controlling multiple smart plugs?

Yes

Operation

What is the default switch state when the smart plug is first energized or recovers from a power outage?

Last state

Reporting Capabilities

What energy-related measurements are available?

Per smart plug: Period energy consumption (kWh); Period energy savings (kWh); Period average energy consumption (kWh); Estimated yearly consumption (kWh). Per device type (load type): Current real-time wattage (kW); Period average wattage (kW); Period energy consumption (kWh); Period energy savings (kWh); Period average energy consumption per device (kWh)

Reporting Capabilities

What reporting periods are available for the energy-related measurements?

hour, day, week, month, year

Reporting Capabilities

If available, what format can the energy-related measurements be exported in?

CSV file

User Interface: Remote Access

What types of user apps are available?

Web portal

User Interface: Hardware

What functions can be performed through the on-device button?

On/Off toggling; Network provisioning; Factory reset
