Request Sync Notification on Boot

Enhancements
1

Request: It would be great if there was an option for an instance to request the current sync state on boot. (Might require 1 instance to be designated as primary)
…

Example scenario: 3 instances, Kitchen, Lounge, Office. All used for Christmas lights. Kitchen and Lounge are powered 24/7, but Office’s power is on a scheduled smart plug timer (due to a loud power supply).

All three instances are set to sync, but if the Kitchen/Lounge preset/effect/brightness/color gets changed while Office is unpowered, when it boots up it will remain out of sync until the next change.
…

Potential Work arounds:

  1. Schedule a preset to coincide with Office power cycle. (Might be possible to write a preset that makes no visible (or at least noticeable) change.)
  2. Write a Usermod that runs once after boot, pulls the current state via the API from a specific instance and applies it locally.
  3. Use IFTTT or similar to control both the smart plug and request and then forward the current state via the API.
    …

Is there any value in this as a feature request?
Have I missed any obvious work around options?
What’s the neatest, cleanest solution?

Many thanks.

That might be an interesting feature, though IMO a niche one.

For 2. you might want to use Auto Save usermod and modify it to do a WebClient request and parse JSON (there is something similar opened as PR on Github but cloud based).

If possible, 3. would seem easiest solution.
