Everytime CLN wants to pay an invoice, or send a keysend, the very first message it sends is either PreapproveInvoice, or PreapproveKeysend. So these should go only to signers that have the send feature. If for some reason the send signer crashes, and broker starts talking to a receiveonly signer, 1) broker will see that it's receive only, so it will wait for a send signer to connect back. 2) if broker still sends, the receive only signer can be programmed to immediately reject any preapprove messages.

configure the hardware (or you can use your Sphinx app)
make a seed: ./newseed.sh
make a .env file like:
SSID={my_ssid}
PASS={my_wifi_password}
BROKER={broker_ip_and_port}
SEED={my_seed_hex}
NETWORK=regtest
connect to the sphinxkey network on your computer
cargo run --bin config
This will encrypt your seed and send to the hardware, along with your home wifi information and broker address
