Can't figure out, why this is not working.

->file.writeline([==[cfg={}]==]) -> ok
->file.writeline([==[cfg.duration=10*1000*1000 -- 10 sec]==]) -> ok
->file.writeline([==[cfg.wake_pin=3]==]) -> ok
->file.writeline([==[]==]) -> ok
->file.writeline([==[node.sleep(cfg)]==]) -> ok
->file.flush() -> ok
->file.close() -> ok
->dofile("main.lua") -> send without checkdofile("main.lua")
main.lua:37: attempt to call field 'sleep' (a nil value)

1. How can I enable this when using https://nodemcu-build.com/ ?
2. I am using master which I thought relates to https://nodemcu.readthedocs.io/en/maste ... ules/node/

You'll have to build the firmware manually as per https://nodemcu.readthedocs.io/en/latest/en/build/. I suggest you use the Docker image.

That's correct, I posted the wrong link. However, IIRC we missed to add that note to the documentation in 'master' when the feature got disabled. It'll be available with the next dev->master snap.
