You should be able to connect a wallet. They’re is a nice in the btcpay server, but don’t give access because I would need to manually sort all transactions, and the security… easier to just connect your own wallet.

Does this guide help? https://docs.btcpayserver.org/LightningNetwork/

I've read it several times, but it hasn't helped. I'm looking for an easy way for less technical people to set up a lightning node without a monthly bill.
