About Atto

Atto is an intelligent gateway designed by NextDrive to collect solar energy data. It makes data transmission more reliable and stable. Atto has a built-in 4G SIM card with RS-485 and two USB ports. With them, Atto enables devices, such as a solar energy system and battery, to import data via physical lines, and then uploads it to a cloud service through the SIM card, thus providing more stable transmission services. It also conforms with the Wi-SUN communication specification of low-voltage intelligent meters in Japan. It can collect data from intelligent meters wirelessly. You will find it easy to automatically collect data on electricity generation and consumption as long as Atto is installed at home.

Supporting Wi-SUN communication

it can be connected to intelligent meters and can read household electricity usage in real time.

With a built-in 4G SIM card

It can independently transfer data and has a more stable network than household Wi-Fi.           

Supporting the RS-485 communication interface,

It can independently detect the B Route data of solar power generation and electricity sales.

ECHONET Lite Certification

Control and monitor smart device, such as Power condition system of battery and solar panel, water heater, air condition system, etc
