Trying to reduce the use of SRAM

Could I badger you for a more detail? How do I use dtostrf() and strcat()?

Did google fail you? Hard to believe.

I'll take that as a no... Google, here I come.

how many do you have that print constant strings that do not use the F() macro?

Off the top of my head: 2. (The rest should be commented out and are only for debugging.) I print temp and humidity to the lcd every three seconds. Both of which use F():

lcd.print(F("Hum: "));
    lcd.print(h);
    lcd.setCursor(0, 1);
    lcd.print(F("Temp: "));
    lcd.print(t);
