As of today (6/15/2022) at 6:00 PM EDT, the Alexa Skill for Insteon was re-enabled, That skill disappeared a couple weeks ago in the wake of the Smart Labs shutdown. But after I spent over an hour on the phone with the Alexa tech team following the reactivation of the Insteon Hubs after new investors rebooted all servers, I convinced Amazon to retrieve it from archive and turn it back on.
I can confirm the skill is active and Alexa voice control of the Insteon Hub is again working.
HOORAY!!
