Paperless-ngx, Firefly III, and n8n are all awesome tools. However, I think connecting Paperless to Firefly via n8n will be very difficult to grab the correct date and amount. What if there is no receipt or the receipt is sent via email? Also, Paperless sometimes gets the wrong date for me, such as when there are multiple dates or the print isn’t clear.
If you’re using a card to pay, I recommend downloading .qfx files from your bank and uploading those to Firefly instead.
There’s a lot of technical answers here, but Tailscale is what you want OP. Self-hosting is only a risk if you open ports. Tailscale doesn’t require opening any ports.
Alternatively, you could set up your own VPN and forward one port to the VPN. The risk of port forwarding to VPN such as Wireguard or OpenVPN is minimal.
The risk of being attacked applies to those that port forward web traffic so it can be accessed without a VPN by themselves or others. If you don’t do that, the risk is very low.
