co2Card

A custom Lovelace card for Home Assistant that checks if CO2 content is in a good range for current grow light PPFD. It has a nice CO2 atom indicator ;)

First try writing a custom card. I know it's not perfect. Any contributions, recommendations and comments are welcome!

Base data used in script:

PPFD CO2 (ppm)
200-450 400
450-800 800
800-1000 1400
1000-1400 > 1400
