OpenEVSE integration not connecting

I have setup the OpenEVSE integration for my EmonEVSE EV charger like so:

sensor:
  - platform: openevse
    host: !secret openevse_ip
    monitored_variables:
      - status
      - charge_time
      - rtc_temp
      - ir_temp
      - ambient_temp
      - usage_session
      - usage_total

However I am not seeing any of the sensors being added
Just see messages like these in the logs:

2021-09-04 16:37:53 WARNING (SyncWorker_4) [homeassistant.components.openevse.sensor] Could not update status for RTC Temperature
2021-09-04 16:37:56 WARNING (SyncWorker_9) [homeassistant.components.openevse.sensor] Could not update status for Usage this Session
2021-09-04 16:37:59 WARNING (SyncWorker_3) [homeassistant.components.openevse.sensor] Could not update status for Total Usage

I do have a username and password setup under the HTTP options so maybe that’s causing it to not load? Does it only work without that?

same issue here and I then removed the username and password and it still wont show anything
