v5.190.38 - fail.

Hi Fibaro Support/Users,

 

I am writing regarding a critical problem with my Home Center 3 installation. I am the installer and end user. The controller is used as the main brain for all lighting in my house, so this is currently a severe issue.

 

Hardware setup

– 1 × HC3 master – Serial number: HC3-000XXXXX 

– 1 × HC3 slave – Serial number: HC3-000XXXX1

 

The master (HC3-000XXXXX) has been running stably for about 5 years and controls all lighting and scenes. The slave is used as an additional controller.

 

Problem

Suddenly, all scenes and Z-Wave control stopped working. The house is effectively without light control (only “dumb” lamps work). At the same time:

– The master HC3 shows a red gear LED / error state.

– The web UI is reachable on the IP address, but only shows the login screen.

– None of my known credentials work (admin/admin, password from label, or previous user credentials).

 

What I have tried (on HC3-000XXXXX)

 

1. Power cycle (several times) – no effect.

2. Recovery Mode via + button:

   – Power off, hold “+” button, power on, release when LEDs start the left-to-right sequence.

   – Yubii Finder correctly shows the unit as “Recovery Mode”.

3. From the Recovery web interface (System A v5.190.38), I have run:

   – Auto Repair

   – Repair System A

   – Recover / Factory Reset from the Recovery screen

4. After Factory Reset, I:

   – Tried to log in with admin / admin → rejected.

   – Tried the password printed on the label → rejected.

   – Tried my usual HC3 user credentials → rejected.

5. I also attempted to restore from Cloud backup after Recovery, but this just restores the previous (unknown) passwords, so I am effectively locked out again.

 

 

In other words:

– I can access Recovery Mode and execute all repair/recover options without error messages.

– But I cannot log into the normal UI at all, even after a Factory Reset, and scenes/Z-Wave do not work.

– The behaviour does not match the manual (which states that after Factory Reset, I should be able to log in with admin/admin on a clean system).

 

Why this is critical

– HC3-000xxxxx is the master for the whole house lighting.

– There is currently no functional Z-Wave control from the master.

– The unit appears to be stuck in a state where Recovery works, but normal system/login is corrupted or not reset correctly.

 

My questions / what I need from you

 

1. Can you confirm whether this is a known issue with the current firmware (v5.190.38 or similar)?

2. Is there an official procedure to:

   – Completely re-flash the firmware on HC3-000xxxxx (beyond the standard Recovery/Factory Reset), and

   – Ensure that the unit comes up as a truly clean system with admin/admin?

 

 

I have multiple cloud backups available, and I am willing to:

– Either restore from backup once the unit is truly clean, or

– Start from scratch if necessary, after a proper low-level reset or replacement.

 

At the moment, the key issue is:

 

Even after Recovery and Factory Reset, HC3-000xxxxx does not behave as a clean controller and will not accept any documented default credentials.

 

I would appreciate a concrete recommendation (re-flash procedure, downgrade, or RMA) and, if possible, step-by-step instructions for the next actions.

 

Kind regards,
Carsten
