This is another module which uses the UART. It was used with a number of Jura coffee machines, which used the common TopTronics electronics used by other coffee machine manufacturers as well. To enable reading out these coffee machines, an ESP8266 module was integrated into a small, plastic enclosure which just had a serial connector on one side. This connected with a standard nine-pin serial cable to the so-called service port on the back of the machine.
The serial port on the machine provided 5V when it was powered on, which thus also turned on the ESP8266 node when the coffee machine was on. The plastic enclosure could then be hidden away behind the machine.
The module for this feature looks like this:
