[X10] Development guidance for adding new devices

[scottgrobinson]

I'm looking to try and add support for the Eufy X10 so I've started down the rabbit hole. I can see what needs doing, however, I can't yet get to the stage of mapping the codes as my device isn't listed.

I get the error

2025-12-14 12:56:06.479 DEBUG (SyncWorker_0) [custom_components.robovac.config_flow] Skipping vacuum AMP96Z0E27400392: found on Eufy but not on Tuya. Eufy details:

Adding a bit more debugging we get

I tried running tuya.m.device.my.list which returns no devices...

I've definetly got a Eufy device!

What next steps can you recomend for debugging this? I'm not too familiar with the Tuya side of things hence reaching out as I imagine you may have spent a little more time there than I have...

I'd like support for X10 Pro Omni, didn't have much success yet

This issue may be related to Protocol 3.5 (AES-GCM). See #285 for tracking the implementation of this feature.
The X10 Pro Omni (T2351) is suspected to use the new 3.5 protocol. The PERMISSION_DENIED error from Tuya API may indicate these devices have moved to a different authentication system entirely.
