MMM-cryptocurrency

A MagicMirror module used to get real-time values of crypto currencies.

Installation

1. Navigate into your MagicMirror's modules folder and execute git clone https://github.com/matteodanelli/MMM-cryptocurrency.git.
2. Add the module inside config.js placing it where you prefer ;)

Config

The entry in config.js can include the following options:

Option	Description

conversion	The currency used to convert crypto currency value. Type: string Options: AUD, BRL, CAD, CHF, CNY, EUR, GBP, HKD, IDR, INR, JPY, KRW, MXN, RUB Default: USD
displayLongNames	Option that show full name of the currency or the shortest version. (eg. Bitcoin/BTC ). Type boolean Default false
displayType	Sets the display of the module. Type: string Options: detail, logo Default: detail
logoHeaderText	Defines the headline text if displayType: logo is set. Type: string Default: Crypto currency
headers	Possibility to show currency change in the last hour, day or week. Type One of the following: change1h, change24h, change7d Default None. All optionals.
significantDigits	Total digits to use for rounding the price (including before and after decimal point). Type number Default 2

Here is an example of an entry in config.js

{
	module: "MMM-cryptocurrency",
	position: "top_right",

Cryptocurrency Logo

Logo provided only for the following currencies:

• Bitcoin
• Ethereum
• Ripple

Feel free to ask for support of your favorite currency. Else, just implement it (eg: to add Litecoin logo):

• Add 'litecoin' to the currency module config
• Create the logo (png, 50x50px)
• Name the file litecoin.png
• Put it in the /publicdirectory of the module
• Restart MagicMirror

Notes

Data provided by coinmarketcap.com.

• Endpoints update every 5 minutes.
• Currently you can only display currencies listed within top-10 on coinmarketcap.com.
• significantDigits only has a visible effect when set to 4 or more. It is useful for showing low-value coins (such as Ripple) at a higher resolution, rounding to more digits after the decimal point than the minimal 2. Rounding always keeps at least two digits after the decimal.

Feedback

It's my first module here after that I built a MagicMirror. I'm so proud of it and I have found a lot of interesting modules, including one similar to this, based on Bitcoin only MMM-bitcoin.
I am open to work on this project and to expand it to add other interesting features, and a bit of cool style too.
Leave me some feedback in the forum. Thank you!
