Sometimes it can get dry.

This can happen if it suddenly gets hot or if the plants grow very quickly. If it gets dry, lift one pot and pour 3-4 dl of water directly into the baseplate. Your Auk will recover and water normally again afterwards.

If the plants are starting to dry out, pour 3-4 dl of water (about a glass of water) beneath the pots, and your Auk will recover.

Your Auk checks how wet/dry it is every time it waters. This check is very accurate, and it also does a double-check by measuring during two waterings. Still, it can make the wrong decision sometimes. If the measurement is wrong multiple times, it can get a bit dry. 

After you pour in some water your Auk will "recover" and take care of itself again. It just needs a little help sometimes :)
