Operating environment (Hass.io/Docker/Windows/etc.): Hassio 0.92.2 in Docker with Proxmox.

Component/platform: Canary – the auto discovered sensors (temp, humidity, air quality) https://www.home-assistant.io/components/canary/

Description of problem: Canary camera component sensors (temp, humidity and air quality) have stopped working. I believe they were last working with 0.90.

Camera feed from Canary still works and the sensor for alarm_control_panel still displays correctly.

Problem-relevant configuration.yaml entries:

logger:
  logs:
    homeassistant.components.canary: debug

canary:
  username: !secret canary_username
  password: !secret canary_passwd
