Hi,
i tried to replace a defect device with the function "replace"
can you explain why the S0 ist grey ? i can only select S2 and no encry

Z wave adapter: 3.1.0
iobroker: v6.13.16
Platform linux
Node.js v18.20.2
NPM 10.5.0

During the replace flow, specific communication with the new device is needed. This unfortunately conflicts with the S0 key exchange ("bootstrapping"), because it causes the new device to abort S0 bootstrapping. I'm not sure why the option is offered though.
