We asked CTO Jon Keeble to highlight solution features

Wattwatchers CTO Jon Keeble does a quick download on favourite features of the energy monitoring devices he’s created:
- Wattwatchers devices can be thought of as internet appliances.
- 6-channel products includes 6 energy meters.
- The 6M communicates over 2G/3G, and 6W over WiFi.
- Devices have three phase voltage inputs P1-3.
- They support 6 current transformers (CH1-6).
- CH1 and CH4 are by default associated with P1, CH2/5 with P2, CH3/6 with P3.
- 3M is the same as 6M except it has only 3 energy meters.
- Many parameters are OTA (over the air) configurable.
- The default associations between P1-3 and CH1-6 can be changed (OTA re-configured).
- Power data is reported at 5-second intervals (configurable to large values).
- Energy data is logged in the meter in 5-minute fixed intervals.
- Hosting services request energy data and so don’t miss data.
- Devices continue to log energy data for weeks even when comms is ‘down’.
- Devices connect to up to two hosting services.
- Devices keep time using an internet connected time server.
- Devices report to and are supported by the WW DMS (device management server).
- The DMS supports installs, and provides configuration, code update, and data validation.
- Devices have no physical controls.
- Factory fitted options support load control and Modbus RTU functions.
- 6W WiFi is configured using a smart phone (WiFi connection and browser).
- 6M is highly secure, using the mobile network and secure internet connections
- 6W protocol uses HTTPS, like a bank.
- 6W supports 802.11b/g/n on 2.4GHz, not 5GHz. Range is better on 2.4GHz.
- Device code update is highly secure.
- Even if a WiFi WPA2 network is penetrated (password stolen?) HTTPS remains secure
- Devices cannot be used to penetrate a WLAN network
- The data in a utility meter mounted outside a house is easily accessed; no password!
- 6M generates about 17MB/month reporting every 30 seconds.
- 6M data can be reduced arbitrarily to about 2MB/month, reporting infrequently.
- Multiphase installs require CT’s to be correctly located: WW on-boarding tools can help.
- Wattwatchers tested to comply with Australian, NZ, European and US (1Q18) standards.
