I had one of my dimmer switches go out recently, and just got the replacement switch in. My new switch responds to adding the device in altsteon_cli with its correct current settings, but doesn’t respond to such commands as “on” or “off”. It simply says “unknown command ‘on’.”
The only difference I see in the old and new switch is it’s been upgraded from v6.0 to v6.5. Seems unlikely that they would alter their commands with such a short revision history, but I’m willing to entertain the possibility. Any other suggestions?
Edit: After a bit of research, apparently after v6.1, these switches now utilize the i2cs protocol. Fortunately, I do use the 2413u modem, so it should be able to communicate with the device, but I’m guessing a whole new set of “extended” commands are needed to get it to react appropriately. I guess this new protocol is probably a step forward for Insteon, but it would have been nice if they allowed them to accept the old commands as well.
