A friend was looking for an app so I explored some FOSS ones. It might be helpful to take it a step further and self host it so that family members can coordinate care.
I saw this which looks interesting
https://github.com/MDeLuise/plant-it/#features-highlight
Open to regular FOSS apps as well!
There is plant-it written in Java and HortusFox written in PHP. Both using MySQL. Is there anything available which is written in Go or Rust and uses SQLite?
I only know of plant-it and hortusfox. I tried both.
I find plant it to be superior. Also, the dev is very nice and open to suggestions and usually implement them pretty quickly.
YMMV
I use home-assistant and a esphome device as a Bluetooth proxy to track plants with some Bluetooth devices (MiFlora I think)
