First time Umbrel node user. I built my node using a Raspberry Pi4 and a 1TB SSD. The process was pretty straight forward and took all of 30 minutes to put together. After boot up, I let my node sync to 100%. After that, I provided liquidity into my on-chain bitcoin wallet.
A few days later, a buddy of mine and I decided to open up our very first lightening channels together. We both decided on 400K sats, and he opened a channel with me for 400K, and I opened a channel with him for the same amount.
After both channels were opened, my Umbrel’s Lightening Wallet is showing his channel having a “max receive” of around 400K sats and a “max send” of 0 sats. Likewise, my channel is showing a “max send” of around 400K sats and a “max receive” of 0 sats.
When we both tried to rebalance our channels using RTL, we both received the “No_Route” error message. At first we thought we were doing something wrong but upon further research, it seems to me that because we each opened up a channel between us and we both decided that 400K sats was going to be our channel size, we theoretically already have a balanced channel together?
Is my reasoning more or less correct, or are we missing something and still need to rebalance these channels?
Does the rebalancing aspect of maintaining lightening channels only come into play when a node has multiple channels open with different nodes?
