Nevermind I guess this thread can be closed. I need to sort the backlight situation but i got the basic setup to work. lcdproc sends and the esp8266 prints the raw data to lcd. I'll use the hd44780 libs and post something on my git but everything that was needed to make this code work was in my third post.
Anyone interested here is the cleaned up version. Backlight is harcoded for now. I,ll look into the hd44780 version once i learn how to code :). It's far from perfect but it's a start and it could be handy. I,ll work on it but for now it seems to do what it need it to do.
