TPLink Tapo Unable to Add Second H200 Hub on New Install

### The problem

I'll leave this posted as the issue I experienced is unusual, although the problem has been mitigated. If I add a new H200 hub that doesn't have any sensors attached to it the issue in HA below occurs. If I add a T110 door sensor to the hub, via my iPhone, I can then add the hub to HA.

---- Original Text.
I'm using HAOS with HA 2026.9.1. I've purchased 2 H200 Hubs and I've not used Tapo on HA before. I set the first Hub up via the Tapo iPhone app and it updated itself to firmware 1.7.5. I installed the TP-Link Smart Home HA integration which detected the first H200 hub and installed correctly. I can view the first hub in HA and its associated sensor.

I then powered up a second new H200, via wired ethernet, which updated itself to firmware 1.7.5. I can access the second H200 via my iPhone. I've set a DHCP static IP for both hubs.

My iPhone's Tapo app:

The TP-Link Smart Home app detects the second hub correctly:

If I add the second hub I'm prompted for my TP-link credentials (which I used to add the first hub):

I then receive an unknown error:

If I manually add the second hub in HA I receive the same error. Both Hubs are connected to wired ethernet and are on the same vlan as HA. I've assigned static IPs, via DHCP, to both hubs. I can ping both hubs from HA without a single packet loss.

I can delete and add the first hub in HA without any issues. If I delete the first hub I'm still unable to add the second hub in HA. I have third-party compatibility enabled.

### What version of Home Assistant Core has the issue?

2026.9.1

### What was the last working version of Home Assistant Core?

N/A. 2026.9.1 is the first version I've tried.

### What type of installation are you running?

Home Assistant OS

### Integration causing the issue

TP-Link Smart Home

### Link to integration documentation on our website

https://www.home-assistant.io/integrations/tplink

### Diagnostics information

_No response_

### Example YAML snippet

```yaml
None
```

### Anything in the logs that might be useful for us?

Debug logging turned on and the second hub attempted to be added to HA:

### Additional information

I've not used Tapo on this system before, so there will be no legacy Tapo files.
