Thanks for your encouraging words!
In the Phoenixd documentation, the autoliquidity section explains the mechanism clearly: the minimum channel size is 2M sats, and the liquidity service fee charged by ACINQ is 1% — that’s 21,000 sats just for the service.
On top of that, the on-chain miner fee must also be paid, which varies depending on network conditions.
Now that you mention it, I’ll start putting together a GitHub repo documenting this setup. It’ll be public so anyone interested in using or improving this self-custodial LNbits + Phoenixd combo can access it freely.
Thanks again — I truly appreciate the support and feedback!

¡Gracias por tus palabras de aliento!
En la documentación de Phoenixd, el apartado de autoliquidez explica claramente el mecanismo: el tamaño mínimo del canal es de 2 millones de sats, y la tarifa por el servicio de liquidez que ofrece ACINQ es del 1%, es decir, 21,000 sats solamente por el servicio.
Aparte de eso, también se deben pagar los fees de minería on-chain, que varían según las condiciones de la red.
Ahora que lo mencionas, voy a empezar a trabajar en un repositorio en GitHub donde documente esta configuración. Será público para que cualquiera que quiera usar esta combinación de LNbits + Phoenixd en modo autocustodia pueda hacerlo o incluso colaborar.
¡Gracias de nuevo! Aprecio mucho el apoyo y el feedback.
Awesome use case - helping Cuban merchants with LNbits + Phoenixd is exactly the kind of real-world, self-custodial tooling we need more of.
From my testing, there's no hardcoded minimum in Phoenixd, but practically speaking, anything under ~6,000 sats often fails due to:
On-chain fee estimates (can spike unexpectedly)
Reserve requirements for the channel
Minor dust limits
The fact that Phoenix opens inbound-only channels, so the whole amount gets locked
When fees are low, you might get through with 5,500-5,800 sats, but if you're documenting for others, telling folks to send 6,000-6,500 sats minimum is safer and avoids edge-case headaches.
Would love to see yo documentation when it's done - I bet others in iow-bandwidth regions
