And just like that, Tesla has moved the goal posts and now requires each domain to have its own certificate registered with a CA from a list they don't provide. Let's Encrypt didn't appear to make the cut, and a CloudFlare wildcard certificate isn't enough either. Support ticket raised.

Tesla Fleet in #HomeAssistant 2025.1 requires users to register their own developer application, which requires hosting a public key on a unique domain. To make this easier I have created fleetkey.cc with @cloudflare.social Pages, Workers, and KV. It lets anyone host their pubkey for free.
