Winix (HA integration)Works CloudHA integration is cloud; local control possible with an ESPHome-flashed ESP32

I have a couple of winix c545's that I like a lot. If you're okay with them being connected through the cloud, there is an HA integration for them. If you would prefer local control, there is a project that allows you to add an esp32 flashed with ESPhome. And because it's the ESPhome, you can also use it as a Bluetooth proxy and/or add other sensors.

Shows as a fan, not an air purifier
Fan entity only; no PM2.5 data so HomeKit air purifier not possible

Sorry, C545 does not provide any PM data. AQI cannot be used as PM2.5. This was the response in this regards from Winix support [code]

Each row is one report from a GitHub thread, an integration’s docs, or r/homeassistant. Check the date and the linked source before you buy.

In ReReHome

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
