The node don't support Grove Base HAT for Raspberry Pi Zero yet.
Install Online one-click installation flow at basic Grove Base HAT setup page.

Try to work various Grove parts before starting Node-RED of Grove Base HAT node :)
Execute following command. npm install node-red-contrib-grove-base-hat
then the node may be installed in "/home/pi/.node-red".
OR
Adding nodes to the palette https://nodered.org/docs/user-guide/runtime/adding-nodes
Connect Grove LED to Grove Base HAT's D18 port.
Import this flow.

Look Grove LED node setting. Check port number in node setting and connecting port number.
Generally the sample flow default port setting is D18. If your setting port is defferent from sample flow D18. Fit port your connecting port and node setting port number.
Click Node-RED inject nodes written 1 and 0. When inject nodes as 1, Grove LED will turn on. When inject nodes as 0, it will turn off.
