Insteon HA integration very slow or not responding

[ChrisMory]

I added my PLM modem to my HA instance in attempts to eliminate my ISY device. While I was successful at adding my insteon switches to HA, they would respond very slowly or not at all. Typically, they would respond normally once or twice, and then just stop, or there would be long delays before a device would respond. Sometimes the delay is 20-30 seconds, other times a couple minutes, or not at all. Occasionally, a device will respond normally for several commands in a row, but inevitably it stops responding or takes an extremely long time to respond.

I reset my PLM and my Insteon switches with hopes that would clean things up. I have only added a single insteon dimmer switch and the same behavior as before. The rest of the Insteon dimmers I have are all offline (pulled the tab out to cut power to them). The PLM only knows of the single dimmer and the dimmer only knows of the PLM.

I'm not sure where to go from here. I've tried different USB ports, rebooted, removed the integration, added it back, etc. Attached are some log extracts that hopefully help. Any recommendations or guidance would be greatly appreciated!
