You're absolutely right. Here's the README with PROPERLY closed code blocks - I'll format it exactly as it should appear in the actual file:

Grow Sensor Card

A custom card for Home Assistant that displays grow room environmental data in an intuitive dashboard format. Perfect for monitoring grow room conditions including temperature, humidity, VPD, CO2, and air quality metrics.

Features

• Temperature readings from multiple sensors
• Humidity levels across different locations
• VPD (Vapor Pressure Deficit) monitoring
• CO2 concentration tracking
• Air quality measurements (VOC, NOx, PM levels)
• Visual trend indicators
• Tabbed interface
• Responsive grid layout

Installation

HACS (Recommended)

1. Ensure HACS is installed
2. Add this repository to HACS:
   • Click HACS in your Home Assistant sidebar
   • Go to "Frontend"
   • Click menu (3 dots) in top right
   • Select "Custom repositories"
   • Add https://github.com/legacygrow/grow-sensor-card
   • Select "Lovelace" category
3. Install "Grow Sensor Card"
4. Refresh your browser cache

Manual Installation

1. Download grow-sensor-card.js
2. Copy to config/www directory
3. Add to configuration.yaml:

lovelace:
  resources:
    - url: /local/grow-sensor-card.js
      type: module

Configuration

Add to your dashboard:

type: 'custom:grow-sensor-card'
entities:
  temperature:
    left_back: sensor.left_back_temperature
    middle_canopy: sensor.middle_canopy_temperature
    left_front: sensor.left_front_temperature
    right_back: sensor.right_back_temperature
  humidity:
    f1_scd41: sensor.f1_scd41_humidity
    middle: sensor.middle_humidity
    left: sensor.left_humidity
    hepa: sensor.hepa_humidity
  vpd:
    f1_scd41: sensor.f1_scd41_vpd
    middle: sensor.middle_vpd
    left: sensor.left_vpd
    right: sensor.right_vpd
  co2:
    f1_scd41: sensor.f1_scd41_co2
    middle: sensor.middle_co2
    left: sensor.left_co2
  air_quality:
    voc: sensor.voc
    nox: sensor.nox
    pm25: sensor.pm25
thresholds:
  temperature: 24
  humidity: 75
  vpd: 0.8
  co2: 1200

Options

Option	Type	Required	Description
entities	object	yes	Your sensor entities
thresholds	object	yes	Alert thresholds

Entity Structure

Each sensor category needs entity IDs:

temperature:
  location_name: sensor.entity_id
humidity:
  location_name: sensor.entity_id

Thresholds

Set warning levels:

thresholds:
  temperature: 24    # °C
  humidity: 75      # %
  vpd: 0.8         # kPa
  co2: 1200        # ppm
