Insteon problems on 0.108.1

[blysik]

The problem

HA is unable to control any Insteon devices through my USB Insteon modem which has been functional for months and months. (See at end, it DOES appear to notice state changes of switches however.)

Environment

HA 0.108.1 running in a docker, /dev/insteonusb mounted inside it.

• Home Assistant Core release with the issue: 0.108.1
• Last working Home Assistant Core release (if known): 0.107.6 (but I reverted back to that, and it didn't solve the problem)
• Operating environment (Home Assistant/Supervised/Docker/venv): Docker
• Integration causing this issue: Insteon
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/insteon/

Problem-relevant configuration.yaml

insteon:
  port: /dev/insteonusb

Traceback/Error logs

Example of trying to turn on a device:

2020-04-09 09:15:33 DEBUG (MainThread) [insteonplm.devices] Starting 40.AD.17 Device._send_msg: Queuing message
2020-04-09 09:15:33 DEBUG (MainThread) [insteonplm.devices] Starting 40.AD.17 Device._process_send_queue

And a full pastebin of restarting my host and docker completely: https://pastebin.com/P9td3f5u

Additional information

HA seems to SEE the devices. If I turn them on, in the Entities view, the graph shows the state changes properly. It just can't turn on/turn off.

Okay, so it turns out this was the same "multiple instances of HA running in the docker", as noticed in issue #32992

I run docker via Portainer, and had to clear out the command, and now things work.
