Our verdict
The bigger sibling of the Core 300S, aimed at open-plan living rooms. Home Assistant control goes through the VeSync cloud, so it is not local, but it exposes the PM2.5 reading and fan modes you need for simple automations.
What can Home Assistant control on the Levoit Core 400S?
| Control | Type | What it does |
|---|---|---|
| Fan | Fan entity | On/off, speed and mode |
| Air quality | Sensor | PM2.5 reading from the built-in laser sensor |
Uses the core VeSync integration with your VeSync account: fan on/off, speed and mode, plus the PM2.5 sensor. Cloud-polled, so it stops responding if VeSync is down. Set it up in the Levoit app first.

Frequently asked questions
- Does the Levoit Core 400S work with Home Assistant locally?
- Partly. The Levoit Core 400S connects to Home Assistant through a certified "Works with Home Assistant" integration (VeSync), which relies on the Levoit cloud. It works in Home Assistant, but commands go via the internet and stop working during an outage of your connection or the Levoit service.
- Which protocol does the Levoit Core 400S use, and do I need a hub?
- The Levoit Core 400S uses Wi-Fi. To pair it with Home Assistant you need no hub — it joins your Wi-Fi network directly. Levoit's own hub is not required when you integrate through a certified "Works with Home Assistant" integration (VeSync).
- How much does the Levoit Core 400S cost in the UK?
- The lowest price we have listed for the Levoit Core 400S is £219.99 at Amazon UK, with other UK retailers at up to £219.99. Prices were last checked in November 2026 and change often, so confirm on the retailer's page before buying.
