Feature Request mqtt IO #235

Open rebe0909 opened 6 years ago

rebe0909 commented 6 years ago

Hello. There ist already mqtt on Board and there are some IO Pins free. So I am wondering if it would easy be possible to integrate an mqtt IO?

e.g. to be configured over the telnet console? Thanks in advance! Kind Regards Reinhard

If you enable USER_GPIO_IN and USER_GPIO_OUT in user_config.h and recompile you can at least use one digital input and one output pin.

You can control the output PIN via an MQTT topic (define it with "set mqtt_gpio_out_topic xxx") and get state changes of the GPIO_IN pin via MQTT "/GpioIn" topic .

Not much of docs right now, but you can see the details in the code of user_main (look for "#ifdef USER_GPIO").

With #293 all GPIO state changes are published via MQTT /Gpio topic.
