MagicMirror Module: mmm-openhab-table

A MagicMirror2 module that fetches item values from an OpenHAB REST API and displays them as a color-coded table.

Supports temperature, humidity, air quality (PM), barometric pressure, and hot water sensors. Colors update based on value ranges. The idea is to change the row color based on the value.

Barometric pressure color ranges based on: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4684554/

Installation

cd ~/MagicMirror/modules
git clone https://git.juliochegedus.com/spectronet/mmm-openhab-table.git

Configuration

Add to the modules array in config/config.js:

{
    module: 'mmm-openhab-table',
    position: 'top_right',
    config: {
        updateInterval: 600 * 1000,
        apiSearch: "http://openhab.example.com:8080/rest/items/",
        itemNames: [ "Temp_lagrange_Out", "Temp_terra_Out", "Pressure_proba_Out", "Humidity_lagrange_Out" ]
    }
},

Configuration Options

Option	Default	Description
apiSearch	http://arch-oracle.science.net:8080/rest/items/	OpenHAB REST API base URL
itemNames	["Temp_lagrange_Out", ...]	List of OpenHAB item names to fetch
updateInterval	600000	Refresh interval in ms (default: 10 min)
retryDelay	120000	Retry delay on fetch failure in ms (default: 2 min)
initialLoadDelay	2500	Delay before first fetch in ms
animationSpeed	1000	DOM update animation speed in ms

Sensor Detection & Units

Item names are matched by pattern to determine units and CSS class coloring:

Name pattern	Unit displayed	Color classes
Temp* / Water*	°C	cold / comfy / warm / hot
*humid*	%	moist
*PM*	µg/M³	clean / acceptable / heavy / polluted
value > 500 (pressure)	hPa	deep / cold / comfy / warm / hot

Temperature thresholds (°C)

Range	Class
<= 17	cold
17 – 27	comfy
27 – 30	warm
>= 30	hot

Barometric pressure thresholds (hPa)

Range	Class
< 999	deep
999 – 1008	cold
1008 – 1023	comfy
1023 – 1028	warm
>= 1028	hot

Air quality thresholds (µg/M³)

Range	Class
< 3	clean
3 – 7	acceptable
7 – 11	heavy
>= 11	polluted

Hot water thresholds (°C)

Range	Class
< 45	cold
>= 45	comfy
