We currently do plan to integrate auto-discovery but we do not plan to make the auto-discovery topic changeable. Is it common to change it?
Somehow related, but a bit off topic is the problem that we can not offer secure MQTT because of memory restrictions that we run into with the SSL connection. If the memory restrictions are resolved in a future product, we would still use it without certificate pinning. e.g. no uploading of a custom certificate is supported.
