Core: 0.86.0b0 MQTT Devices Not Loading

[mynameisdaniel32]

Home Assistant release with the issue:
0.86.0b0

Last working Home Assistant release (if known):
0.85.1

Operating environment (Hass.io/Docker/Windows/etc.):
Debian

Component/platform:
MQTT Light, Switch, Sensor, Binary Sensor

Description of problem:
Since updating to the 0.86 beta, all of my MQTT devices are broken. I seem to get an error for each MQTT entry I have (I've only copied a small sample, as there's lots of them).

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):
Again, just one example

switch:
  - platform: mqtt
    name: Sprinkler Zone 1
    icon: mdi:water
    state_topic: "node/sprinkler/006/state"
    command_topic: "node/sprinkler/006/command"
    availability_topic: "node/sprinkler/006/availability"
    payload_on: "1_on"
    payload_off: "1_off"

Traceback (if applicable):

Same error here with Tasmota Discovery and with manual configuration.

I think this can be caused by files moved in PR #20050 still being present.
Can you confirm which commit you're on?

HA 0.86.0b0

[emontnemery]

Thanks.

Then this is caused by stale files present after the renaming of files in PR #20050:

Instead of, for example:
/srv/homeassistant/lib/python3.5/site-packages/homeassistant/components/sensor/mqtt.py
You should have a file:
/srv/homeassistant/lib/python3.5/site-packages/homeassistant/components/mqtt/sensor.py

If you have both, it should be safe to remove:
/srv/homeassistant/lib/python3.5/site-packages/homeassistant/components/sensor/mqtt.py

Reposting my comment from discord:

The wheel package for 0.86.0b0 is tainted. Sdist works. Workaround:

pip uninstall -y homeassistant
pip install --pre --no-binary=homeassistant homeassistant

[emontnemery]

@balloob You mentioned on discord the underlying issue causing the bad wheel package has been fixed, so this can be closed?

[balloob]

Yes
