Add MIoT support for Xiaomi Robot Vacuum S40C EU

[borsuk85]

Summary

Add a dedicated MIoT integration for xiaomi.vacuum.e101gb (Xiaomi Robot Vacuum S40C EU).

This model does not work correctly through the legacy RoborockVacuum path, but it is locally controllable through MIoT. This change adds a dedicated MiotDevice-based implementation instead of relying on GenericMiot.

What is included

• new XiaomiVacuumE101GB integration
• stable status() implementation using small get_properties batches
• actions:
  • start
  • stop
  • pause
  • resume
  • home
  • find
  • start_room_sweep
  • start_zone_sweep
• room helpers:
  • room_information
  • room_ids
  • zone_ids
  • get_room_configs
  • get_zone_configs
• consumable reset actions:
  • main brush
  • side brush
  • filter

Implementation detail

The device does not always echo the request did in property responses and may return the device id instead. Because of that, the integration maps status responses by (siid, piid) instead of relying on did.

The generic MIoT status query is also too wide for this device and may time out, so status() intentionally reads a smaller, stable subset of properties in batches.

Verified on real hardware

Tested locally against:

• model: xiaomi.vacuum.e101gb
• firmware: 4.5.6_0127

Verified:

• status reads correctly
• home() works
• room metadata is readable
• start_room_sweep("3") starts cleaning
• home() returns the vacuum to the dock afterwards

Tests

Added unit tests for:

• status parsing
• preset setters
• action payloads
• room/zone payloads
• consumable resets
• response mapping when the device returns device id instead of request did

@borsuk85 Hi Michal, did Teemu gave you some signal that he will merge this at some moment? Thanks.

[borsuk85]

Hi, no, I haven’t received any signal from Teemu yet. The PR is ready from my side and was tested on real hardware, but I’m waiting for maintainer review/merge.
