Rigavit Pro

This is a smart device that cares for your indoor plants while you are busy or away. It automatically chooses the best time to water your plants through some integrated temperature, light, humidity and soil moisture sensors in it. Or you can also set it manually when you want it to water your plants.
It is Wi-Fi connectable so it can be easily monitored from up to 5 miles away. Pretty cool.
It has a solar panel that helps recharge your batteries for constant power or it can also be charged from its USB outlet.
This also alerts you when your batteries are almost down or when the water in the bottle is finished. This is an awesome device to monitor and water your plants with.
