I have a light systems that uses wall appliance switches and a ir-543 controller. I use a Logitech Harmony remote to turn off and on the lights. When I turn on my home theater it will turn on lights that should not be turned on. What is causing this?

[Brian H]

Are the lights and the Home Theater controlled by the Harmony or do the lights just go on when you turn on the Home Theater directly?

[caddyroger]

They are controlled by the Harmony remote.

Bad Harmony.   

I'm sorry, sometimes I just can not stop myself.

Ok seriously, can the Harmony control each light individually?
Did the Harmony ever turn on the home theater correctly? If so, have you tried reprogramming the macros in the Harmony?
The IR-543 pretty much receives the IR code from the remote and applies it to the powerline, it should not be causing the problem.

  Yes the Harmony can be used to turn on and off lights. There no macros to program. It can control what ever the IR-543 control. In the the Harmony devices setup under home automation it has x10 pro and x10 wireless. With my TiVo setting it will turn on my living room light and turn off the rest. With the dvd it will turn off all lights.
 Just every once in awhile when starting 1 light will turn on but most of the it will turn back off.

If you unplug the IR-543 does the wrong lights On thing stop?
Do you know if the TiVo uses RF of IR commands and if RF do you have any X10 Transceiver's that can process RF?

Besides Brian's questions I have another. You seem to be saying the same lights are messing up with the same equipment commands. Would the lights happen to be the very last lights the Harmony controlled before you Tivo'ed or before you DVD'ed?

If they are, try this: on the Harmony, set up a fake X10 switch module, same as you currently have in service,  (unit number isn't important) on a house code you do not use. After you control your lights and prior to controlling the TiVo or the DVD, send an ON or OFF command to the fake light switch....do the lights still mess up?

Sidebar question to anyone who knows: The IR 543 can couple any IR transmitted HCUC? i.e. the HC set on the IR 543 is only for the IR 543 unit code buttons.

I'll try that.

This harmony uses IR commands  to control the lights.

So if you disconnect the IR-543 and the strange light actsions stop. You know the Harmony is sending an X10 command or an IR sequence used by the home theater is being misread as an X10 command.
