Fish tank has an IP address

Turn on that fish tank filter, your fish will thank you!  But I like to turn it off during feeding time.  Every time when the filter motor stops, they anticipate treats and swim towards surface, bubbling up like puppy dogs!  But once in a while, they take a long time to finish dinner, and no one remembers to turn the filter back on until everyone is in bed!  No need to get up, the fish tank has an IP address!  Turn the the fish tank filter on/off, monitor the temperature, etc.
