I recently installed a new 2478D SwitchLinc Dimmer, Dual-Band, 120/240V, 50/60Hz 600W. When I linked it to my ISY 99i running 3.1.17 it reported as "Unsupported Device:1.49"
I presume this is because this is a new SwitchLinc model from Smarthome? Regardless, the ISY is able to control it except for setting a specific on level percentage in a program.
Let me know if there is some additional information I can collect to help add this to the list of devices that ISY supports.
Thanks
