Treatlife Smart Ceiling Fan Control DS03

Quick verdict

The Treatlife DS03 is a budget favorite for smart ceiling fan control. Out of the box it uses Tuya cloud, but it can be flashed to Tasmota via Tuya-Convert for fully local operation. Check your hardware version before buying, as newer revisions may require serial flashing instead of OTA.

Standout: Budget single-gang fan and light switch that can be flashed via Tuya-Convert OTA for local smart home control.

Compatibility snapshot

Why it stands out

• widely available and budget-friendly

Reasons to hesitate

• stock firmware is fully cloud-dependent via Tuya
• newer versions may have patched Tuya-Convert OTA flashing
• only supports 4 fan speeds which may not match all ceiling fans

Best for

• budget-minded users who want smart fan and light control and are willing to flash firmware
• anyone already using Tuya or LocalTuya in their Home Assistant setup

Privacy and local-control notes

Stock Tuya firmware is cloud-dependent. Can be flashed with Tuya-Convert (OTA) or serial flashing to Tasmota for fully local control. LocalTuya integration provides local control without flashing.

Home Assistant support: supported · integration path: Tuya / LocalTuya / Tasmota.

Buying reality check

Price notes: One of the cheapest smart ceiling fan switches available. Excellent value especially if you can flash it to Tasmota.
