A while ago I started a little thread in this forum to initiate a plant/flower database that one day could be integrated into homeassistant’s plant monitor. It was also featured on the homeassistant podcast. That way the user would only have to enter an plant ID into the config file and the min/max values for brightness, conductivity, moisture, etc. and a corresponding entity picture could be fetched from the web. To this date the database has collected around 40 plants/flowers ranging from tropical bananas to good ol’ kitchen basil. Please feel free to contribute.
Actually thats a bit of a voodoo thing. Regarding my plants I usually just observe them. You get a feeling for the required min/max values. The only thing I never really understood is the conductivity value. It’s measuring the plants need for fertilizer and I think it measures the electric current but this value also goes up if you just water your plants.
In the thread linkes above someone mentioned the API used by the original Xiaomi App but noone was able to pull this database. It’s really huge like 3000 plants and more but the data is not accessible so far.
