Fan speed dropdown broken in HA 2026.02+ (MWC components removed) — fixed fork available

[3ative]

The Problem

As of Home Assistant 2026.02, the fan speed dropdown no longer works. The menu items (e.g. Off, Standard, Boost IQ, Max) are rendered as a permanent flat list instead of a collapsible dropdown menu.

This is because HA's frontend has been migrating away from Material Web Components (MWC), and the mwc-menu and mwc-list-item elements that renderDropdown() relies on are no longer globally registered.

The Fix

I've published a fork that replaces the broken MWC dropdown with a native HTML <select> element. This has zero dependency on HA's internal frontend components, so it won't break again with future updates.

• Fork: https://github.com/3ative/lovelace-xiaomi-vacuum-card
• Release: https://github.com/3ative/lovelace-xiaomi-vacuum-card/releases/tag/v4.5.1

Installation via HACS

1. Open HACS → three-dot menu → Custom repositories
2. Add https://github.com/3ative/lovelace-xiaomi-vacuum-card with category Dashboard
3. Search for Xiaomi Vacuum Card and install
4. Restart Home Assistant and clear your browser cache

Note: If the dropdown still appears broken after clearing cache, try fully closing and reopening your browser — HA's service worker cache can be persistent.

All other functionality and configuration options remain unchanged from v4.5.0.

As workaround a good idea

I would have but, as the last PR was closed over 3 years ago - I assumed no one was maintaining.
