I setup a channel balancing service that takes payment from your locally funded channels and pushes it to your remotely funded channels.

It worked for me to balance Lightningto.me's channel with my node.

Feel free to try it with small amounts, remember this is custodial and payment to your node may fail even if there's a route so your satoshis may get stuck and you'll need to manually contact me if that happens.
