Retry when Dht11 fails (seems to fail 2 times in a row then work on third attempt)
Use Progmem
Add LCD support (i2c 20x4)
Use a define, also increase by 1 to give the pot a dead spot (avoid flicker)
Misc housekeeping
Delay not needed
Encase in F()
Add basic web server (and foundation of web client)
Not quite ready yet, but trying to finish web client
Get off pin 13 (SPI/Ethernet)
Now function ajax calls, also reworked how timers will be used
