Keypad MQTT on ESP

[Curtis777]

Hey Guys,

I got stucked.
I plugged a keypad as picture attached.
PCF8574 with GPIO 0 and GPIO 2
and setup my MQTT

all i want is that every keyinput should be reported to my MQTT Broker
connection to my broker is working
but the states are not reported to the MQTT Broker i only see the state -1 which i setted as startup script

If the plugin is working you will get an event in the log. You then need rules to act on the event. Unless you changed the label in the device page you will get
the event "ScanCode" with a 2 digit value. You need to write some rules to do anything from that event. See the code notes at the top of this page.
