How to get the wallet address of my own LND node? I have set up a lighting node using LND time ago, now I would like to send more BTC to it.

How can I get the wallet address of my LND node?
Use lncli h to view a list of all the available commands. 

lncli newaddress will give you a new address for the wallet. You must specify the address type: either p2wkh (pay to witness key hash), or np2wkh (nested pay to witness key hash). For example, lncli newaddress p2wkh.
