Connect two Home Assistant instances together

Hi,
I have one RPi 3B+ with Razberry Z-wave GPIO card that I now want to connect to a new HA instance that I’m running on a server.
I have installed HACS and home-assistant-remote on the server and the config looks like this:

remote_homeassistant:
  instances:
  - host: ip
    port: 443
    secure: true
    verify_ssl: false
    access_token: !secret rpi_access_token
    entity_prefix: "zio_"
    include:
      domains:
      - sensor
      - switch
      - light
      - group
      - zwave
    subscribe_events:
    - state_changed
    - service_registered
    - zwave.network_ready
    - zwave.node_event

I can see my light on the server but I can’t turn then on or off the light.
I just got this error.

When I go in to the RPI i can turn on and off the lights.

Have I missed something?
