How do I add the RTC Time Module library to Arduino development environment?
https://nodemcu.readthedocs.io/en/maste ... s/rtctime/



Compiler complains that "rtctime was not declared in this scope"

Is this module for LUA only?

Yes, this is LUA only ...
But you can use ESP.deepSleep() in Arduino.

That is what I'm using now but the "RTC Time Module" has some cool additional features.
Maybe I'll try to port it.

The ESP8266 (and ESP32) / Arduino could really do with a better time/sleep library, able to do things like the RTC Time module and things like regular short and long sleeps synchronized with real time in a power efficent way, etc. If you or anyone else is interested in working on this, perhaps in a Github project, I'd be happy to help towards that too, let me know.
