I have been using insteon through an old isy994. I have a serial plm connected to my HA instance and have been slowly moving devices over to it. The isy died so I wanted to move everything over quickly. Once done, the devices do not seem to report state back to HA if they are turned on at the switch or through a insteon link. Also if turned on from HA they do not seem to send to other linked devices. For example I have two light switches that are cross linked so they both work together. If I turn either switch on the other one comes on, etc. This still works, although HA does not show either as on. If I turn either switch on from HA then only the one switch comes on, the linked switch does not. I have gone through the aldb links and both switches have a controller/responder pair for the other switch and a controller/responder pair for the PLM. I am not sure what to do next.
