Revert worked fine! My HomeBase 3 is now back working.

@lenoxys we need to check more why this is breaking the HB3, but I have double checked with @danymexi and the revert worked.

Hi @max246, @danymexi, understand the revert to unblock users.

However, I can't see how #779 could break HB3 — every change is device-gated (T8214/T8425 serial checks, isBatteryDoorbellDualE340()/isFloodLightT8425() guards). The only generic code path is the try/catch around RSA in CMD_GATEWAYINFO, but for HB3 RSA should succeed as before and the ECDH fallback is never reached.

A few questions to help investigate:

• What exactly broke on HB3? Events, livestream, connection, everything?
• Any logs or error output? Even a snippet would help narrow it down.
• Was this tested directly with eufy-security-client or through a downstream project (homebridge plugin, HA add-on, etc.)?
• Is there an issue tracking the HB3 problem?

Without an HB3 to test against it's hard to investigate, but happy to help if you can share more details.

I have a HB3, I can try to debug it, just didnt have time to dig up too much. I had multiple tickets raising the block :(
I asked Dany to run this branch on his system and it just worked again.

If you want to test yourself, you can run a docker image and HA. It fixes other stuff so I want this PR back in, just dont want to break everything else.

@max246 Let's work step by step. I've opened #793 with only the device-gated changes (T8214/T8425 registration + livestream routing). No session or encryption changes. Should be safe to merge and verify HB3 is unaffected.

If it passes, we can re-introduce the ECDH/encryption parts separately.

@max246 Second PR opened: #795 — ECDH encryption support, now gated by device serial prefix (T8214/T8425 only). HB3 and all other devices should hit the exact same RSA path as before. Depends on #793.
