charge-lnd VS plugins

and then follow the instructions from https://github.com/accumulator/charge-lnd/blob/master/INSTALL.md

I use charge-lnd to automatically rebalance by channels via fees. My charge.config is heavily inspired (stolen) by this article.

I use charge-lnd to adjust fees proportionally to the channel state encouraging outflow if most the sats are on my side, and discouraging further outflow if most sats are already on the peer side.

charge-lnd v0.2.13 (Released: 23th November 2022) - https://github.com/accumulator/charge-lnd/releases

for LND, https://github.com/accumulator/charge-lnd can be configured to do this.

Charge-lnd v0.2.11 - Release page- Upgrade guide add sum_peer_chans to proportional strategy to consider multiple channels to the same peer; docker: proper fallback for tls cert when TLS_CERT_PATH is empty string; allow using variables in config files; improve robustness w.r.t commas and whitespace in chan/node list files

charge-lnd v0.2.9 - Release page - Upgrade guide don't match channels on activity_period criteria if the channel is younger than the activity_period; add command parameters --tlscert and --macaroon; support SSL for electrum servers; fix error in fallback when a strategy returns an error

I made a bit more than OP on fees using my node, since I discovered charge-lnd to automate fees, see https://github.com/accumulator/charge-lnd and also do your research and open good channels to good routing nodes :)

And c-lightining's feeadjuster plugin https://github.com/lightningd/plugins/tree/master/feeadjuster 🤗

Here is a C-Lightning plugin that accomplishes much the same objective.

There seems to be a plugin for rebalancing https://github.com/lightningd/plugins

Sure, I'll make a PR, but they're not very responsive to my PRs. So if I do make it you should expect it to appear in my lightning-tools repo's plugins dir.

Absolutely. If you look at the rebalance plugin (https://github.com/lightningd/plugins/blob/master/rebalance/rebalance.py) you'll notice most of the code tries to do some best effort guesses as to how to best balance channels. The actual code to compute the route is relatively simple:

C-lightning has a plugin that'll adjust the fees on channels based on the balances in the channel, i.e., higher fees if an htlc would drain funds from an already low channel and lower fees to encourage rebalancing channels with high outgoing capacity: https://github.com/lightningd/plugins/tree/master/feeadjuster
