MMM-Soliscloud

MagicMirror² module for displaying Soliscloud inverter data.

This module pulls data from the Soliscloud API and displays it as a simple table on the MagicMirror.

Screenshots

Installation

Just clone the module into your modules directory and install the dependencies:

cd ~/MagicMirror/modules
git clone https://github.com/dekinet/MMM-Soliscloud
cd MMM-Soliscloud
npm install

Update

Just enter the MMM-PublicTransportHafas directory, pull the update and install the dependencies:

cd ~/MagicMirror/modules/MMM-Soliscloud
git pull
npm install

Configuration

There are a number of configuration options available:

Option	Default	Description
intervalSecs	300	Defines how often to poll the API for data. Don't do this too quickly, or your requests will be rejected by the server.
lastUpdated	true	Display the timestamp of the last time data was sent to the server by the inverter.
currentPower	true	Display the current power generated.
dayTotalGenerated	true	Display the amount of power generated today.
monthTotalGenerated	false	Display the amount of power generated this month.
yearTotalGenerated	false	Display the amount of power generated this year.
totalGenerated	false	Display the total amount of power generated.
price	false	Display the current price.
dailyIncome	false	Display the daily income value.
allIncome	false	Display the total income value.
displayAlarms	true	Display the most recent alarm (if active).
alarmTimeFormat	"lll"	Moment display string used for formatting the start time of the most recent alarm.
gpioOnAlarm	0	Set the Raspberry Pi GPIO number to drive when an alarm is active. Setting to 0 disables this feature. Tested on a Raspberry Pi 3 B+.
gpioOnAlarmState	"high"	If driving a GPIO pin is enabled, the pin will be driven to this state when an alarm is active. Valid values are "high" and "low".

In addition, the MM config file must include you Soliscloud API key and secret. There are no default values for these.

An entry in the module configuration file might look like this:

    {
      module: "MMM-Soliscloud",
      position: "top_right",
      config: {
        intervalSecs: 600,
        yearTotalGenerated: true,
        allIncome: true,
        apiKey: "123456",
        apiSecret: "abcdefg",
      }
    },

Dependencies

• MagicMirror²
• base-64: Used to base-64 encode requests/data sent to the API
• crypto: Used to create a digest of data sent to the API
• onoff: Used to activate GPIO when alarms active

Styling

A simple styles.css file is included. The generated data utilises the following classes:

Class Name	Used
soliscloud-data	The whole generated div
soliscloud-table	The table containing Soliscloud data
soliscloud-row	All rows in the table
soliscloud-cell	All cells in the table
soliscloud-alarm	Applied to the entire ALARM row (if active). Flashing red by default.

Limitations

I only had access to one inverter, so received data from multiple interverters is not handled. Fixes are welcome. Alarm handling is very basic and not well tested. Only the most recent active alarm will be displayed (if alarms are configured to be displayed).
