The invention refers to a heat exchanger plate and a plate heat exchanger. The heat exchanger plates are arranged beside each other in the plate heat exchanger to define several first plate interspaces for a first medium and several second plate interspaces for a second medium. The heat exchanger plate comprises a heat transfer area, an edge area, which extends around and outside the heat transfer area, and a device, which is configured to receive or produce a signal. The heat exchanger plate also comprises a communication module comprising an electronic circuit connected to the device and communication means permitting communication of said signal with a master unit via at least a communication module of another heat exchanger plate in the plate package.
