Bumbershoot

@Guy Lavoie, @BobM99, @Techman, @Pmool, @joepoway, @Geddy, @TheA2Z, et al -- Michel responded to my ticket last night (at roughly 10:00 pm Pacific), and the fix worked, so I'm back in business.  According to the log, it appears that there was an update to the ISY 5.8.4_1 software.
Please reboot using the following method: 1. Press/hold power button -> red 2. Click again -> blue  

Yes it is, and it works (though not as elegantly as an Insteon scene).  Here's a good thread describing how to set this up: 
 
 

I bought three Ring outdoor stickup cameras at Costco years ago, and they work very much like the Ring doorbell regarding motion detection.  The Ring Polyglot plugin works just fine, though there was a time when it wasn't functional.  I hope those days are past...
 

Assuming that you're on the latest/greatest firmware: Right click on the device/node you're interested in, select "X-Ray" from the context menu.  An X-Ray window will pop up, then select "Node Info" from the drop down list, and click on "Go".
In the example in the screenshot, the device is "ZY007_1", and the value you're looking for is "Lumin".  The value in your email would look like this: ${sys.node.ZY007_1.LUMIN}

You don't have to declare anything.  Just create the variable (in this case, $s.KitchenLights is a state variable, which is why I prefix the name with the 's' - If it were an integer variable, I would have named it 'i.KitchenLights').
Once you've created the variable, it's available to use in programs.  You have to select the ">" symbol in the AC program interface to select the % or variable you want to use.  See screenshot:
 

It's not so simple, but if you want to avoid the Hue bulb turning on when this program runs, you could do this: take the Hue bulb out of this program, and write a second program that looks for the desired initiating event, and when it sees that event, sets the attributes for the Hue light, which will turn it on.  It might not be a completely seamless visual effect, but...  

Not sure what's up, but the motion nodes don't have any displayable properties that indicate motion.  As for the programs, did you restart the AC after you installed the node server?  Be sure to use "Control" in your programs instead of "Status".
Below is a program that I'm using, and it's working like a champ.
Outdoor Motion - [ID 00CC][Parent 000F] If 'Devices / dirPolyglot / Ring / Ring / Front Door (Motion)' is switched Motion Or 'Devices / dirPolyglot / Ring / Ring / Deck - West (Motion)' is switched Motion Or 'Devices / dirPolyglot / Ring / Ring / Deck - East (Motion)' is switched Motion Or 'Devices / dirPolyglot / Ring / Ring / Side (Motion)' is switched Motion Then Resource 'Device Notification' Else - No Actions - (To add one, press 'Action')  

Here's what the variable substitution value looks like for an ECOWITT moisture sensor: 
${sys.node.n005_wh51_1.ST}
You can click on the "Nodes" button on your node server to see the values for each device.  
Below are the possible values for the moisture sensor:

The passwords aren't connected.  Change it in the console.

I'm using the Occupancy Node Server built into the UDI Portal, in conjunction with the Locative app on our iPhones to provide this.  It's worked for some years very reliably, and it works on my Polisy.  The instruction for setting this up are here:

A couple of us have had the same results with those repeaters, and UDI is aware of it:
 

No, it's not bad storage.  It's been this way for a long time.  Here's mine:
 

@Snibley, the Station ID is a five digit number (you can find it under the "Status" menu), and you have to use that value in a Custom Parameter in the node server configuration, "Add Custom Parameter":
Key        <your five digit station id>
Value     local

@ronlovetri, you have to go to the Security & Privacy icon within an hour after you tried to open the app by the unidentified developer.  Have a look at this link: https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac
 

You can use the portal.  Select Tool | Information | ISY Information | URL to ISY
Copy the URL to ISY value and past it into a new entry in the ISY Launcher and you're good to go.

Well, I simply checked for status of this single detector (the status on this detector changed when any of my other hardwired detectors saw smoke), and this always worked as intended.  I replaced these detectors with wireless Elk detectors quite a while ago, so this solution is no longer in use, but it worked:
Smoke Bridge - [ID 004D][Parent 0013][Not Enabled] If 'Devices / dirMasterBedroom / Smoke Bridge-Smoke' Status is On Then Set 'Devices / dirLivingRoom / ZW 007 Siren' On Wait 2 seconds Set 'Scenes / scnAllInteriorLights' Fast On Wait 2 seconds Set 'Devices / dirGuestBedroom / flcFan-Light' Fast On Wait 2 seconds Set 'Devices / dirGuestBedroom / sldGuestVanityLight' Fast On Wait 2 seconds Set 'Devices / dirGuestBedroom / sldGuestShowerLight' Fast On Wait 2 seconds Send Notification to '3' content 'Smoke Detector Alert' Wait 5 seconds Set 'Devices / dirLivingRoom / ZW 007 Siren' Off Else - No Actions - (To add one, press 'Action')
