#72884 I get this error when I try to compile a sketch for an esp8266 12e. This sketch complied with an Uno.
ISO C++ forbids comparison between pointer and integer [-fpermissive]

Code: Select allif ((now.hour() == OnHour1) && (now.minute() == OnMin1) && (now.day() == OnDay1) && (now.month() == OnMonth1)) {
    digitalWrite (relay1, LOW);
    lcd.setCursor(1, 2);
    lcd.print("ON");


This is the complete code
Code: Select allLiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);  // Set the LCD I2C address Ox3F (Check yours)
RTC_DS1307 rtc;    // Create a RealTimeClock object (I set the time in another sketch)

#76241 In your code "now.hour() == OnHour1" OnHour1 is a pointer to an array. So, the statement would have to be something like "now.hour() == OnHour1[0]" to be valid.
