i would love to have an app, that reminds me of when to water or fertilize my plants, depending on the plant species, weather and light conditions.
maybe even automatically turning off and on the growlights.
just to maximize plant health.
We're working on a free Home Assistant plugin that let's you define your sensors and outputs, then choose a plant (see link below, or climate of a specific location) and hopefully take most of the heavy lifting from there.
