Sanitary system

A sanitary system comprises 5 at least one sanitary article (1a, 1b, 1c, 1d, 1e) respectively having a sanitary article controller (2) and an actuator (3), wherein the sanitary article controller (2) is configured to drive the actuator (3) according to the intended use and wherein the sanitary article controller (2) has a sanitary article communication interface (SK1), at least one gateway (4) having a gateway communication interface (GK1) and 10 a memory (5) which is connected to the gateway communication interface (GK1), and a processor (6), wherein the at least one gateway (4) is connected via the gateway communication interface (GK1) to the sanitary communication interface (SK1) via a data connection (D), which data connection (D) is configured in such a way that operational data of the sanitary 15 article controller (2) and/or of the actuator (3) are transmittable to the gateway (4) via the data connection (D), wherein the memory (5) is configured in such a way as to store the received operational data, and wherein the processor (6) is configured in such a way as to evaluate the received operational data, 20 and wherein, when a predetermined evaluation criterion is reached from the evaluation of the received operational data, the processor (6) provides an isolated control instruction. SANITARY SYSTEM TECHNICAL FIELD 10 The present invention relates to a sanitary system according to Claim 1. Networked sanitary systems are known from the prior art. For example, DE 93 13 983 Ul 15 discloses driving of various sanitary elements with a central controller. WO 2009/061857 reveals the linking of a sanitary infrastructure to the Internet. SUMMARY OF THE INVENTION 20 It is an object of the present invention to provide a networked sanitary system which has extended functionalities. This object is achieved by the sanitary system according to Claim 1. According thereto, a sanitary system comprises 25 at least one sanitary article respectively having a sanitary article controller and an actuator, wherein the sanitary article controller is configured to drive the actuator according to its intended use or to specification, respectively, and wherein the sanitary article controller has a sanitary article communication interface, at least one gateway having a gateway communication interface, and 30 a memory which is connected to the gateway communication interface, and a processor. The at least one gateway is connected via the gateway communication interface to the sani
