I have a light that is setup as a 3-way switch using Insteon switches that are cross linked. When I turn the light on or off at either one of the switches the status on the other switch updates as well. However when I turn the light on or off via PowerHome the status on the slave switch doesn’t update. I thought I read a post that states this is by design of Insteon and if you wanted to update the status of the slave switch you would have to use a trigger. Unfortunately I was not able to find this post again so now I am not sure.
If this is indeed true I was wondering why PowerHome, since it know about all links, could not update he slave switches by default. PowerHome could read the link table and send the appropriate command to each of the slave switches automatically.
If what I understand is incorrect does anyone have any idea why the status of the slave switch doesn’t update?
Thanks in advance,
Randy

Randy,
In order for PowerHome to control the LED's of the slave switches, you have to either setup a group in the PLC that has the load and the slave switches and send the on/off command to that PLC group number OR you can setup a macro to do it.

Fasttimes,
Thanks for the information, at least now I know that everything is operating normal. The only problem with the group solution is that you cannot have a group show up on the control screen (or web page) as a device. In a perfect world it would be great if PowerHome could query the links list to determine what devices should be updated when a device is controlled from the control screen. I am sure there is probably a reason but I just thought I would ask.
For now I will proceed with the trigger/macro solution and move on to my next challenge.
Thanks,
Randy

The reason it doesn't query the links is, suppose you have something linked to that switch that, when you MANUALLY use it, you want to also be controlled, but suppose, via powerhome, you just want to control that one light. For instance, every time you turn on the bathroom light, you also want the fan to come on. However, if you want PH to turn on the bathroom light to a dim level for a nightlight, you wouldn't want it to query the switch and say, Oh, I need to turn on the fan as well.
Granted, in a load/control environment (3-way, etc) you would want this to happen, but having it do this everytime leaves you open to loops, etc when setting up scenes. This also will increase traffic, having to query everything every time.
Just my thoughts on this. I do understand the logic you're requesting, however

[QUOTE=RandyH] Fasttimes,

If you are talking about the device status screen in PH or the web-page version, you are correct, those do not show groups.
That would be a neat add-on, to show PLC groups.

Cmhardwick,
Thanks for the feed back. The example that you use with the bathroom light and fan is very good. I can see where you would not want to have the responders updated for some devices. However this could be easily avoided with a check box on each device’s setup screen which would allow you to either have the responder links updated or not. As far as traffic I don’t see this as an issue since PH could query its DB directly to understand the relationships with the responders. The only additional traffic would be the Insteon commands sent directly to each responder to update them. In this scenario PH would be able to participate in normal 3-way circuits as well as not updating responders as in your example.

I'll see what I can do about creating a virtual device for the Device Status screen for the PLC groups. That will probably be the cleanest way to implement this.
Dave.
