Profit on Lightning is mostly fee capture minus capital cost and channel churn. Most Raspberry Pi nodes never cover the opportunity cost of the locked BTC.
Actionable, in order:
Track forwarding fee revenue / (channel capital * time) in sats/BTC-year, not total fees. If that is below your hurdle (even 1-2%), you are a hobby node.
Do not open channels to random high-capacity peers. Open to destinations with stable inbound demand (exchanges, popular LN addresses, LSP hubs) and keep the other side for your own spend/receive. Amboss/LNNodeInsight traffic is lagging; your own forwardinghistory over 14 days is the real signal.
Automate rebalance only when expected fee > on-chain + PPM cost. Blind circular rebalances are how nodes go negative.
Charge enough PPM to matter (often 100-500+ on scarce outbound) and a small base fee so tiny payments are not free work.
If you cannot watch it daily, use an LSP / hosted channel instead of a routing node. Routing is a business; a Pi at home is usually not one.
