This product from the manufacturer EHEIM offers you an intelligent version of the basic version with additional features and benefits. The EHEIM + automatic feeder is a feeder with digital control via WLAN. All functions can be programmed and controlled via smartphone, tablet or computer / MAC. You can set a separate meal time, quantity and generate a day off (hungry day). There is protection against overeating and you can receive an email when the food in the drum runs out. It is also possible to synchronize with other devices in a WiFi program.For example, when connected to the heater EHEIM thermal control + e, you will be notified by email before meals if the water temperature is too high. When connected to the EHEIM professionel 5e external filter, the flow rate can be automatically reduced or increased by 10 minutes during feeding. The feeder has a power supply, so it does not work with batteries like the standard automatic feeder.
