Great video! I only have the Wemo D1 Minis, so I can't do RTC, but was talking to a coworker today about this. I'm a newbie still learning! This was very helpful! Thank You!

Wow, thank you you are a life saver

In my case there is an error that 'RTC' object has no attribute 'irq'... I'm using micropython v1.13 on ESP32 and the RTC module only have 3 methods ['__class__', 'datetime', 'init', 'memory']

[@nihadabbikar5788]

can you implement the same with internal RTC of ESP32 in Arduino IDE,
By the way, It's so interesting and awesome!!!

I have never used the ESP32's internal RTC with Arduino, but this forum thread appears to have a few good leads for what you want forum.arduino.cc/index.php?topic=726949.0
Good luck!

AttributeError: 'RTC' object has no attribute 'irq'

Where do you find the documentation for this? This doc docs.micropython.org/en/latest/library/machine.RTC.html init RTC like this
rtc = machine.RTC()
rtc.init((2014, 5, 1, 4, 13, 0, 0, 0))
Do you know why they are different?
