When I changed the setup in AH-Pro, they worked fine.
THEN, I tried the application I was working on. In the test, it was to send an ON command, followed by a series of DIM commands (95, 90, 85,...) every 10 seconds. The lights came on alright, but never dimmed.
I see from AH-Pro's activity monitor that when dim levels are changed through it, Extended Codes are sent instead of bright/dim commands, so I'm concluding that is why my application is not changing the brightness.
However, since trying the application, I can no longer control the switches except manually. If I try to use AH-Pro, there is no response to any command (on, off, extended codes for dimming). I have tried switching them off with their hard switch for several minutes before trying again, but they remain totally stuck.
How can this be fixed?
