Fritzbox_netmonitor integration with 2 Fritzbox in Mesh Configuration

Hi,
I have 2 Fritzboxes. A 7590 as Router and a 7490 as a mesh Repeater.
I´m trying to use this config:

  - platform: fritzbox_netmonitor
    host: 192.168.1.254
    name: fb7590
    scan_interval: 5
    
  - platform: fritzbox_netmonitor
    host: 192.168.1.253
    name: fb7490
    scan_interval: 5

The values for the 7590 are fine, but for the 7490, all numeric values are “0”. Could it be that this integration does not work in a a mesh environment?
I´m only interested in the uptime value, any idea if i can get it another way?

is_linked: true
is_connected: false
external_ip: null
uptime: 0
bytes_sent: 0
bytes_received: 0
transmission_rate_up: 0
transmission_rate_down: 0
max_byte_rate_up: 0
max_byte_rate_down: 0
friendly_name: fb7490
