To understand the error, you must first understand the protocol. Broadlink devices use a proprietary UDP (User Datagram Protocol) broadcast system for discovery. When you click “Learn” or “Write” in Broadlink Manager, the software sends a broadcast packet: “Are there any Broadlink devices on this network?”
If you continue to experience issues, visit the BroadLink community forums or the Home Assistant BroadLink thread, where developers continue to refine detection for these versatile but sometimes finicky devices.

Here’s a quick Python script that avoids the GUI entirely. Save as send_code.py :
Unplug immediately; switch to a dedicated 5V/1A power brick. Open BroadLink App →right arrow →right arrow Disable "Lock Device". Network blockages To understand the error, you must first understand
As Broadlink has continued to develop its hardware and firmware, the company has made significant changes to the way newer devices authenticate with third-party applications. This authentication change has had a cascading effect, breaking compatibility not only with Broadlink Manager but also with some Home Assistant integrations for these newer devices.
By following these steps, you should be able to get your Broadlink device communicating with your local smart home manager. Disclaimer: Local vs. Cloud For users looking to avoid cloud dependency entirely,
If you compiled Broadlink Manager yourself via Python, you might have an outdated broadlink library (e.g., v0.9 vs v0.18). Old libraries don’t recognize newer devices like the RM4 series, resulting in the “compatible device not detected” message.
Tap the in the top right corner to open Property . Scroll down to find the Lock device toggle. Turn Off the toggle to allow local network communication. Step 2: Use AP Mode Without App Binding
