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.
