- | =====Power Requirements===== | ||
- | |||
- | The input voltage range is 12-24V DC. It consumes less than 2 watts of power without accessory devices. | ||
- | |||
- | =====Connectivity===== | ||
- | |||
- | WattmonMINI has two ways of connecting to the Internet. The built-in LAN can be connected directly to a laptop or router, and is used for setup and local monitoring (but can also be used for remote monitoring if the site has an Internet connection). The USB Host port works with a selected number of USB Cellular dongles (GPRS and 3G), allowing both outbound and inbound data via the Internet. Although we provide instructions on configuring your local dongle, not all of them work. Need a compatible USB dongle for remote monitoring? Use one of our Huawei dongles, the [[hardware: | ||

- | * Kaco (RS-485) | ||
- | |||
- | Any AC Power Meter with Modbus output can be monitored: for example, the [[hardware: | ||
- | |||
- | In addition, if needed, the 5V and GND lines can be connected for device power. Although designed primarily for a two-wire connection to an RS-485 capable device, by modifying a Cat5 cable any of the Modbus devices we have developed (voltage, current, frequency, <tooltip title=" | ||
