Arduino megae nextion enhance touchscreen with rtc
real-time clock scheduler or esp scheduler. my goal is is to use real-time clock scheduler or esp scheduler and schedule so I come to on and off by relays at certain times of day based on real-time. And on my touchscreen display have an override button to turn off but the time is still counting down. From what I have read some of these clocks can lose track of time over a long period in one month can be out as much as 10 minutes because eventually all of this equipment will be housed in the box I don't want to be manually updating the time if i can get way with it that's why I am thinking esp but even that loses time after about a hour, my nextion enhanced has a built-in rtc does that matter if anybody could spare me the time and tell me the pros and cons on both of them and which particular model to go for. Thanks Paul.
