TypeError in Home Assistant when using homeassistant text sensor

[pauln]

Operating environment/Installation (Hass.io/Docker/pip/etc.):

• esphomelib v1.10.0, running on Ubuntu 18.10
• Home Assistant 0.85.0 (hass.io)

ESP (ESP32/ESP8266/Board/Sonoff):

WaveShare e-Paper ESP8266 Driver Board (using esp12e board config)

Affected component:

Home Assistant text sensor

Description of problem: I was thrilled to see that esphomelib supports the WaveShare e-ink/e-paper displays, and dove in to get my 7.5" panel up and running as an ambient display for my Home Assistant instance. I haven't yet managed to get any state data though, as Home Assistant (0.85.0) throws a TypeError when it tries to set the state in the protobuf message.

Problem-relevant YAML-configuration entries:

text_sensor:
  - platform: homeassistant
    name: "Temperature"
    entity_id: sensor.temperature_probe
    id: temperature_test

Traceback (if applicable):

(from Home Assistant logs)

During handling of the above exception, another exception occurred:

Additional information: I tried to extract individual properties of the state by setting the entity_id to (for example) sensor.temperature_probe.battery_level, but then esphomeyaml complains that Entity ID must have exactly one dot in it - so it doesn't seem possible to work around it in this manner.
