It could be really cool with a widget that could display the sensor values from plant related sensors like soil moisture, light, air humidity and nutrient levels from a given plant.
You would then add one instance of the widget for each plant.
In the widget you would be able to select plant type and this would ensure correct thumbnail and preferred levels so you can easily see if you need to water, move or feed the plant.
I came across this video that gives some nice inspirational ideas:
But it lacks some of the features I mentioned. It would be nice to see a Homey widget that has these features where you can select sensors from any connected soil moisture sensor device.
