Janus II Gateway
A Linux-based, CE certified, small form factor appliance for provisioning, aggregating and backhauling data from Meazon metering and sensor devices to online analytics services (either Meazon Analytics or an alternative preferred solution) over Ethernet. Thanks to the user-friendly provisioning web application UI, minimal configuration effort is required even for large scale deployments.
Meazon Janus (in ancient Roman religion is the god of beginnings, gates, transitions, time, doorways, passages and endings) is equipped with a powerful Sitara ARM Cortex-A8 at 1GHz and 512MB DDR3. Its storing ability is based on the size of the embedded MMC and works with a state-of-the-art Ubuntu Linux distribution.
Network-time synchronization is available, and even when not, a Battery-Powered Real Time Clock certifies accuracy of measurement/event timestamps. The Gateway is capable of transmitting control and data messages throughout the ZigBee network, which in turn can be monitored using a variety of provided IP-based protocols, such as MQTT, FTP, Websocket or HTTP(s).
The monitored data reported by the ZigBee sensors (i.e. meter & sensor data, sensor events/alerts), can be stored in a local SQLite database which then can be exported in CSV file format. Janus has a versatile Python platform, developed by Meazon, to connect ZigBee to TCP/IP-like protocols. This service called ZigPy has a modular design which makes it easily extendable.
