More flexible config mode reset about homie-esp8266 HOT 9 CLOSED

At first, Homie-ESP8266 was designed for NodeMCU v1.0, but this obviously has to evolve.
To sum up:

• We keep the NodeMCU button as the default reset trigger. Not sure about this, though
• setResetTrigger(D4, HIGH, 6000) customizes the reset trigger
• setResetFunction(func). if func() returns true, the device resets. But setResetFunction() is already a function that allow to define a function to run (e.g. clean custom EEPROM) when a reset is triggered. Maybe we could rename this one setResetHandler() or setResetHook? The hook one is the most explicit, as it is actually an hook
• disableResetTrigger() disables the inner reset trigger only

It seems clever for me to keep the default reset trigger. Note that to have an ESP8266 to boot from flash (normal boot) you need to have GPIO0 high, so in most set-up GPIO 0 will be pullup.

For "manual" reset I was more thinking to a Homie.resetConfig() method that can be called from the user code (basically from the loopHandler) that just directly trigger the reset...

The loopHandler is only called when the network is in a good state (connected to both Wi-FI and MQTT). So if you want to reset because you've changed your Wi-Fi credentials, you're stuck as the loopHandler will never be called. So a resetConfig could eventually be called from the loop(), but this is sad to add code there, where there is only a pretty Homie.loop() call.

good point :)
Maybe one can add a warning about that in the doc !
So your solution with a callback fct is clearly better.

I'll need all this for one of my devices where all GPIO are used. So I'll work on this when I update the FW of that device (to make it use Homie). However I don't know when it will be...

I'll create a proper documentation, as the project is becoming more and more feature-rich. ;)

I don't know how I will implement those methods either!

Docs are more complete about the loopHandler now. More flexible reset is the next thing I will implement.

Great ! Nice work 👍

I hope to have some time to test it one evening next week...

Thanks !
