As pointed out.
You need an Insteon 2412U or 2413U. USB interfaced PLM.
Smartenit still has some in the options choices. Their choice to what they may have at the moment.
The PLM is very hard to find. As the company closed earlier this year but some of the employees are starting a new company. The 2413 style PLM also has a power supply issue. With poorly chosen capacitors in a switching power supply. Later revisions had better caps.
Like the CM11A the CM15A will not work. They are X10 controllers not a PLM interface to the outside world.
