Algorithm

@IndyMike thanks for posting that. I've been using similar programs for years, and like you I keep them disabled and only enable them when I know there are updates pending. But it's good to have them brought to the foreground again, where others may benefit from them as well.

Problem solved; thanks for the reply though. With Event Viewer open, I ran the program to set the reduced on-level, and was surprised to see ISY attempting to write to several different devices, with the bathroom SwitchLinc being last of all, and taking about a minute-and-a-half, which explains the delay. On examining the devices, I discovered that they were all wireless devices which had updates pending, and a closer look showed, in the Administrative Console, that the button to automatically write changes to wireless devices was enabled. I normally keep that button disabled, and it seems that when ISY reboots, it enables that button--something to be aware of in the future. With that button now disabled, and again running the program, response was immediate, and all is back to normal.

In each of two bathrooms, I have a 2474D SwitchLinc 2-Wire Dimmer controlled by a 2420M Motion Sensor. These motion sensors (and all the motion sensors throughout the house) are configured to send ON-only commands, and are directly linked to the SwitchLincs. Now on either side of the master bedroom bed is 2334-222 8-button KPL. When a certain button is turned on, and if it is dark (approximately between sunset and sunrise), it causes the corresponding bedside lamp, and the bathroom lights, to come on at 35% brightness, and then runs a program which uses Adjust Scene to set to 35% the ON LEVEL of the bathroom SwitchLinc scene controlled by the motion sensor. All of this has worked fine for years. Last Saturday, we had a power outage which lasted eight hours (we have very few power outages, and have never before had one anywhere near this long). When the power came back and the system rebooted, everything appeared normal, apart from a couple of dead KPLs, which are being replaced. But, and here is the issue, those bathroom SwitchLinc / Motion scenes are behaving strangely at night (though they are fine during the day). When the bedside KPL button is turned on, the bedside lamp and the bathroom light both come on to 35%, as they should. But the instant one walks into the bathroom, the bathroom lights immediately comes on to full brightness. Then, perhaps one minute later (when the motion is again triggered), the bathroom lights return to 35%, and thereafter operate properly for the rest of the night. So it seems that the Adjust Scene command is indeed setting the scene's ON LEVEL, but that either that Adjust Scene command is delayed (there are no programmed delays in any of the related programs), or the SwitchLinc's response to that adjustment is delayed (which seems really bizarre). The ISY log shows the remaining commands, but does not show the Adjust Scene commands (presumably by design), though they are obviously being sent. Also, I don't know what the built-in delay of the motion sensors is; whether they send a new ON command every ten seconds, or every minute, or some other interval; so I don't know how many times the motion is re-triggering and sending a new ON command, once or many times, before the SwitchLinc responds to the adjusted ON LEVEL. I have tried a Restore on the SwitchLinc, which did not change anything. Looking for some further troubleshooting ideas.

Set the NO contact to trip a TriggerLinc (Open/Close sensor); set the TriggerLinc to send On and Off commands on separate group. Al

I can confirm that (at least some) KPLs do have that issue. I had one KPL in a pedestal (long since replaced) on which several, but not all, of the buttons developed that very problem. Al

Yes, you can have a (not hot) spare ISY. Should the on-line ISY fail (and the PLM remain okay), all that is required is to replace the failed ISY with the spare, and then do a restore backup to the new ISY. Provided the backup is current, you should be back in business. This is much simpler than replacing the PLM, which requires every device to be updated to the new PLM's address. Al

Since the switches are inside the garage at the man-door, the seond switch may have been intended for a light outside that door--do you have a light there? Al

When we sold our house last August, I removed all the old switches, though I had no intention of re-using them. But I did not want to deal with any problems arising from them being there. We showed the house with the switches in place, but placed a condition that the switches would all be removed before possession. In the new house we installed all new switches (the latest). As it turns out, almost every light in the new house uses switch legs and requires two-wire SwitchLincs, so the old switches would not have been useful here anyway. Now I have a box full of old switches . Al

How do you know it will not resend--are you monitoring with Event Viewer? If indeed the second command is never sent, it may be because each of your programs contains either a Wait or a Repeat, and those are the two commands which allow a program to be interrupted. In this case, your condition Time is Sunset is true for exactly one second, and would therefore be false by the time the Wait has ended. Try If Time is From Sunset For 30 Seconds instead, and let us know if the second command is now being sent. Al

What does 'Mailbox is open' contain? Make sure it has both a subject and a body. Al

As Brian said, make sure the fan's manual control is set to High. As per Teken, most fans have some amount of noise. To test, set the FanLinc to High, then use the fan's manual control to cycle through high, medium, and low, to see if there is any noise. Al

Two wrongs don't make a right, but three rights make a left (if you're driving around the block.) Al

I'm trying to understand this? Have you not heard the expression "Two wrongs don't make a right?" Al

Welcome, Mike. I've used exactly that procedure with a PT-1230, and concur with your opinion of the results. When I started with Insteon (2006?), I used an inkjet printer to make labels for the clear buttons that came on the KPLs at that time. In my opinion, the Brother clear-tape labels look much more professional (and they are very durable.) But more recently, rather than remove labels from pre-etched buttons, I've just bought the blank white buttons and applied the clear-tape labels. The downside is that you can print only one colour per tape, so if one likes colourful labels, then the inkjet has an advantage.

Hello JP, So according to the summary, the program ran, but no command was sent? Try removing and recreating the setpoint line in THEN, save (and ensure it is enabled), and test.
