EDISMA Announcement of launch of new HEMS product and start of photovoltaic system monitoring service

2015.01.07

In April 2012, the Company launched the “EDISMA Energy Management System” service business, which can save energy and conserve energy by visualizing energy and controlling equipment, and in July 2012, launched stores, buildings, factories and apartment houses. Service (EDISMA BEMS) and home services (EDISMA HEMS) since October of the same year.

We are pleased to announce the launch of EDISMA-H002E, a new product of EDISMA HEMS, and the provision of an ancillary service, "Photovoltaic Power System Monitoring and Security Service", from February 2015.

This new product is a variety of HEMS such as visualization of electricity in the home, measurement of gas and water usage, indoor temperature and humidity, ON / OFF control and temperature adjustment of home appliances such as air conditioners from outside. In addition to the functions, it also has a function to monitor the power generation status of the solar power generation system using HEMS data.
This is the first service in Japan to provide HEMS with home PV system monitoring function and maintenance and maintenance services in-house.

We will continue to provide an environment where a wide range of customers can use energy efficiently and comfortably.

option

Flow transmitter Equipment that sends flow data from water and gas meters to the main unit. Connectable to two meters (regardless of gas or water). Compatible with pulse measurement and 5-bit telegram communication.
Wireless temperature and humidity sensor A device that transmits temperature and humidity measurement data to the main unit. Has 920MHz wireless repeater function. (* 1)
Smart tap For 100V / 15A, 100V / 20A, 200V / 20A
A device that connects to a wall outlet or power strip, measures the power consumption of home appliances, and sends it to the main unit.

New product features

Power measurement and power visualization functions

The power consumption, power generation, and power sales measured for each breaker unit of the distribution board (maximum of 14 main circuits and branch circuits) are stored in a cloud server, and can be used at any time with a PC, tablet PC, smartphone, or other terminal connected to the Internet Check your power usage anywhere.

Compatible with multi-maker ECHONET Lite devices (* 2)

By connecting to devices from a wide range of manufacturers that support the ECHONET Lite of the domestic standard, you can use functions that enhance convenience such as ON / OFF control and temperature adjustment of air conditioners from outside. (* 3)
In addition, when an error occurs on a device connected by ECHONET Lite, it is possible to analyze the error details collected by EDISMA HEMS and provide quick maintenance and repair services (* 4).

Abundant optional equipment

By using optional equipment such as gas / water flow transmitters, temperature / humidity measurement sensors, and smart taps that measure the power of individual devices on a per-outlet basis, extended services such as energy management and watching over the entire house are possible. You.

Adopting multiple communication methods considering various installation environments

In addition to a wired LAN, it has adopted a 920MHz band specific low-power radio that has excellent wraparound characteristics and is difficult to place radio interference, so that it can be used in both existing and newly built environments. In the future, a Wi-SUN communication module for linking with smart meters will be installed.

"HEMS photovoltaic power generation system watching set" incidental service

We provide a new service that utilizes HEMS data, "Safety monitoring service for solar power generation".
EDISMA Remotely monitor the power generation status on behalf of customers based on the power generation data, power generation system information and weather data collected by HEMS. In the event of an anomaly, we provide a one-stop maintenance service for photovoltaic power generation systems, from contacting customers, visiting inspections from our service bases to repairs (* 4).

System Configuration
