5. Troubleshooting (HA)
Stuck at the connection step
| Symptom | Check |
|---|---|
| EZS... doesn't appear in the Wi-Fi list | Reconnect power and wait 1 minute. If it's an already-registered device, hold the button 5 seconds (reset) and retry |
| 192.168.4.1 won't open | Make sure your phone is connected to the device Wi-Fi (EZS...) (not your home Wi-Fi). Turn off mobile data briefly |
| Saved, but the device doesn't show up in HA | ① Are the blind and HA on the same router? ② Any typo in the broker IP/port/account? ③ Is the Mosquitto add-on running? |
| No MQTT integration at all | Add the MQTT integration in HA + install the Mosquitto add-on first (1. Requirements) |
Problems during use
| Symptom | Check |
|---|---|
| Card exists but shows "Unavailable" | Check the device power/Wi-Fi. If the device LED blinks at 3-second intervals, it's reconnecting — wait a moment |
| Slider only does 0/100 | The device's Upper/Lower Limit Setup isn't done — it works normally after setup |
| Entity disappeared | Send EZS_HADISCOVERY$ to re-register (4. Advanced Commands) |
| No response when sending a command | Check that the command starts with EZS_ and the topic is /<device ID> |
What happens to the device when HA (the broker) goes down?
Even if the broker briefly disappears due to a NAS reboot, HA update, etc., there's nothing to worry about:
- The device keeps trying to reconnect automatically, and reconnects on its own when the broker returns.
- Meanwhile, the remote and buttons still work normally.
- If the device LED blinks once every 3 seconds, that indicates "reconnecting."
I deleted the device from HA and now the LED is blinking
If you delete the device's account from HA (Mosquitto), the device is refused a connection and enters Setup Mode (LED blinks 3 times). - To use it again: restore the account and wait a moment for it to return automatically, or re-set it up via Method A in 2. Connecting the Device. - To go back to the EasyRoll app: hold the device button 5 seconds (reset), then register in the EasyRoll app.
I want to revert to the EasyRoll app
- While connected to HA, send
EZS_MQTTAWS$(4. Advanced Commands) — or reset the device and register it in the app.
If it still doesn't work
