[FeatureRequest] Custom Parameters and their Units

[TheRealFalseReality]

Is your feature request related to a problem? Please describe. Somewhat. A few already open issues include a lower bound of 0, and no negatives, and the ability to rearrange the parameters.

Describe the solution you'd like I really like this card, but I use it for my Aquarium parameters, which share some parameters for a pool, but a few others that do not. This includes Ammonia, Phosphate, Nitrate, Nitrite, and Dissolved Oxygen, and probably a few others. Would it be possible to add these parameters? Or perhaps the ability to add custom parameters and their units? It would make the card very flexible!
I use my own device and EZO probes for salinity, pH and DO and log toxins with number helpers.

Describe alternatives you've considered I'm just not very familiar with creating custom lovelave cards, so I dunno if this is even possible. To my knowledge, there are no cards directly available for Aquariums, but this is the closest I have seen for my needs, and it is nearly perfect for monitoring toxin ranges at a glance! I'm just using number helpers to log the parameter data and displaying them with graphs, but I think having a range bar would be much better!
