I have configured the app and code to control the relay at the alarm time.
I have referenced the famous blynk scheduler open source code.
(Automatic scheduler. ESP-01 with 4 Time Input Widgets)
Alarms set to a few minutes later work well.
However, daily alarms do not work well.
App alarms are turned off in a few hours.
It is expected to cause nodemcu is rebooted.
Can I keep the alarm settings even if the hardware reboots suddenly?
