X-10 device control not working after 111.0 change to pyinsteon

Up to 110.7, control of X-10 devices (switches, lights) was working.
There’s a noted change in the release notes, but the entity IDs are still there, and the log shows activity when attempting to operate an x-10 switch or light, but the device does nothing.
I’ve power-cycled the Insteon PLM itself, and of course restarted HA numerous times.
What details or logs can I supply to help diagnose?

Same issue here , did you get this fixed? I went into my insteon app on my phone and the x10 devices were gone so i added them back to the hub/app then they worked fine from the insteon app but no joy from home assistant after a restart. Config still looks good in ha and nothing out of the ordinary in logs.

Yes. The author of the Insteon integration addressed it, and it’s corrected in release 111.4.
