Michael,
Does the RF communicate directly through through the isy 99i or through the PLM? The only device that work is the dual band dimmer. Is there a way to reload the firmware on the isy 99i? When I tried to load the new firmware is when everything went dead.
A month ago i upgraded the firmware and everything quit working. I have left it all pluged in and now just getting back to it. I did a manual reset on the unit. This erasd everything. I got my one and only dual band dimmer switch to work but nothing else is working. On the ISY 99i box the bottom bright blue light is on but it doesnt look like it is transmitting or recieving anymore. Its been a month but i thought the transmit and recieve lights blinked more often. Do you think this is a firmware issue or did the PLM die? Since my one dual band switch is working i assume that it is working through RF? Any suggestions at this point would be helpful. I had just started and have about 12 devices so far. Not sure if i need to reinstall the program on the sd card?
