Oh gotcha. It seems to print out for me, at least I thought it did.

I would like to have a log-function on my esp8266 that allows me to print text and stuff using print/println/printf and allows me to redirect the output to either serial or a spiffs circular buffer (to view over a web-interface). I'm thinking the log method should store printouts to RAM (to allow printing in time critical contexts) and once every now and then in the main loop it dumps the RAM-buffer to serial or spiffs.. is there something like this out there?

An application event log. Mmmm. Interesting, yes.

Maybe it could also be interesting to log free RAM and some other stuff periodically and show as a graph on the web-ui besides the event log

@larsenglund I have library for logging to Syslog server (, but it isn't usable for time critical code logging.
I use it for logging headless gateway between MQTT and custom protocol at 433 Mhz.

hey folks, someone able to help me out optimizing my code? i am pretty sure i can consolidate callback() and fauxmo.onmessage(). i think its pretty inefficient right now due to fauxmo.onmessage() sending a mqtt command topic to the broker and thats coming back to the callback() function to do the actual switch. thanks for any help!

Hello, I am using EEPROM for obvious reasons. So, in actual code I don't use it more often, like, to read data lot or to write data. I use it for occasional events to store the status of those events incase of system reloads itself, those info get reloaded. My question is, since I am these EEPROM functions much is it better to add EEPROM.begin() wherever I need and end it with EEPROM.end() or it's good to begin it at the begining of the programme and never end it.. please state the reason too. I have many such things working around in my program. I don't know which way is efficient.
Since I am NOT using these EEPROM*

Does anyone have an example .ino file with the new-ish wifi event handling. I thought I understood it, but I was wrong. I had the deprecated version working with the Wifi.onEvent(), but I can't find a working example of the non-deprecated version.
