======WattmonMINI======

{{ 20180906_wattmonmini-dc_20180907_screenshot_from_datasheet_.jpg?400|WattmonMINI DC}}The WattmonMINI is a reduced version of the [[WattmonPRO]] with a single Modbus RTU port. It is a smaller and more cost effective product with less features, designed for the sole purpose of collecting data over RS-485 and transmitting it to the web:  current sensors, power meters, inverters and charge controllers can all be connected to the Modbus for remote monitoring and control.

Compared to the [[WattmonPro|PRO]] and the [[WattmonMEGA|MEGA]], which support Modbus, RS-232 Serial and several other <tooltip title="Inputs/Outputs">I/Os</tooltip>, the MINI supports only RS-485 Modbus RTU/TCP. Although it does not have the <tooltip title="Input/Output">I/O</tooltip> connectivity of the [[WattmonPro|PRO]] and the [[WattmonMEGA|MEGA]], the MINI has the same "look and feel," with an identically functioning firmware, OS and web interface. The MINI utilizes the same Ethernet and USB GPRS/3G/4G LTE interfaces as any of the [[hardware:Wattmons]] including its predecessor the [[WattmonPro|PRO]].

For power the MINI has a wide input voltage range of 12-24V DC.((There was an early release of the MINI that was powered with an inbuilt AC adapter and functioned on anything between 80 and 240V AC. This AC version of the MINI is no longer available, and only a few were produced. In all other respects it is identical to the current DC powered model. For those that might have one of these AC powered MINIs:  {{20160813_wattmonmini_datasheet_rev1.0_.pdf|WattmonMINI AC DataSheet}} {{20170525_wattmonmini_20180902_rotation_.jpg?75|WattmonMINI AC}})) Similar to the [[WattmonPro|PRO]] and the [[WattmonMEGA|MEGA]] it consumes less than 2 watts of power without accessory devices.

The MINI can be used for **//any RS-485//** application in monitoring, control and data logging for the <tooltip title="Internet of Things">IoT</tooltip>. But particularly noted applications include:
  * **Inverter Monitoring** - Inspect generation and efficiency of gridtie and hybrid inverters
  * **AC Power Monitoring** - Supervise load and performance of substations and mini-grids
  * **Off-Grid Battery Monitoring** - Observe battery voltage, current, SoC, charging trends and health over time
  * **[[:power_control|Zero Export & DG Protection]]** - Reduce active output power of multiple inverters to regulate energy generation

====Quick Start Guide====

The Quick Start Guide is a regularly updated manual that sheds light on some of the basic and/or essential configuration for the WattmonMINI running the latest WattmonOS version.

====User Manuals====

These User Manuals, while initially written specifically for the [[WattmonPRO|WattmonPRO]], are relevant to the WattmonMINI too:((These User Manuals are somewhat "dated," having been written during times when the newer Wattmons had not yet been released, and they sometimes feature or show specific [[hardware:Modules]] or [[:Hardware]] that are obsolete (no longer available). However, the OS is the same for all of the Wattmons. Therefore the hardware differences are the only thing to keep in mind when using these manuals, especially the [[Wattmon|Original Wattmon]] and [[WattmonMINI]] which do not have the additional <tooltip title="Input/Output">I/O</tooltip> ports that are provided on the [[WattmonPRO|WattmonPRO]] and [[WattmonMEGA|WattmonMEGA]].))
