Device update Failed [504] when setting a Scene to turn off everything

[Andydrew1994]

Hi All i hope someone help me regarding this,

What issue do you have? Please be as thorough and explicit as possible.

When triggering a native Apple Home "Leave Home" batch automation/scene to turn off all household lights simultaneously, a few eWeLink lights physically turn off at the wall but continue to report as "On" in the Apple HomeKit UI.

Checking the native eWeLink mobile application reveals that the physical switches have successfully registered the status change as "Off". However, the Homebridge live status log captures explicit 504 Request Timeout errors during the mass action, leaving HomeKit completely out of sync for some devices.
Gemini Ai has advised me that eWeLink updated its cloud infrastructure to strictly rate-limit concurrent requests and this might be the issye

The issue has newly started within the past ~2 months despite a previously completely stable setup.
Actually gemini proposed a temp solution to try to turn off the lights in batches to avoid blasting ewelink all at once, but i didnt try it yet

Details of your setup.

• Do you use (1) Homebridge UI-X (2) Homebridge CLI or (3) HOOBS?
  Homebridge UI

• Which version of Homebridge/HOOBS do you have?
  V2.1.0

• Which platform do you run Homebridge/HOOBS on (e.g. Raspberry Pi/Windows/HOOBS Box)? Please also mention your version of Node.js/NPM if known.

• Raspberry Pi, nodejs v22.22.3

• Which version of this plugin (homebridge-ewelink) do you have? Has the issue started since upgrading from a previous version?

• i have updated to the latest version v12.14.1 but the issue still presists

• Which eWeLink devices do you have that are causing issues? Please include product models if applicable.
  im using Dual R3 and mini R2, but the devices are random

Please paste any relevant logs below.

here is the log when i set the leave home scene, in this case only 2 devices were left out of sync, but sometime they are 5 or 6 devices
