So this is a little confusing.

My ISY is no longer responsive. Programs don't run. I can't bring up the console. However, when I open Mobilinc Pro, I can see that according to Mobilinc Pro, the state variables show a last updated time that corresponds with my most recent power cycling. So that implies that Mobilinc is somehow able to see what the variables are and somehow knows the ISY was power cycled.

I've tried with and without the PLM. I've tried power cycling several times. I've tried rebooting my router.

Any other suggestions on what to try before I throw in the towel?

The usual first suggestion has been to turn off the power, take out the memory card, and clean the contacts with an eraser.

No joy. Anything else?

The second most common suggestion is to try another power supply. Sometimes it will still measure 12v with a meter, but not work.

Hmmm, easier said than done since I don't have a spare power supply. Anything else?

I've been trying a few other things.

1) Pressed the device reset button, and after a few minutes, I was able to read and change variables via Mobilinc. I also was able to test that the variables are readable by IFTTT. But it still won't control devices nor can I log in to the admin console.

2) I tried replacing the PLM with a spare. I'm now able to see the status of my Insteon devices, but I still can't control them. When I walk over to the switch and manually turn it on or off, Mobilinc can see that the state changed. But controlling the switch doesn't work. And still can't log in to the admin console.

3) Put the old PLM back in, and I regained control of devices. Almost everything is now working. But I still can't log in to admin console.

Any other thoughts before I try a factory reset?

If Mobilinc can connect isy is working. I think you need to be more specific about "can't log in to the admin console". Can't find IP Address? Credentials not accepted? Something else?

Are you able to log into your router and check to see an active connection and get the ip address? With the ip address, try putting http://xxx.xxx.xxx.xxx:8080 (substituting your ip address for xxx.xxx.xxx.xxx) into the java iox finder manually and see if it pops up with the unit being present. If so, obviously open it.

Also, try using ssh to log into it. In windows, type "powershell" into the search box to open powershell. from the prompt, type ssh admin@xxx.xxx.xxx.xxx (again, subsitute your ip address) and then the password is also admin which it will prompt you for if is alive and responding at that ip. If you have apple, I don't know how to open an ssh session, but I'm sure you can google it.

But again, I would take the earlier advice of a new power supply. I'm sure you have a suitable one somewhere in your house, just be sure it has sufficient amps. I forget what that number is, but look at your current ones amp rating and find one with at least that many amps. This is where power supplies fail, they peter out on the supply amps, so they may register 12v when under no load, but as soon as you start pulling a load, the volts drop. ISY can sort of work under these circumstances, which is seemingly your issue.

Also, replacing the plm is likely to cause more issues than it solves. To properly replace a plm, you need to be able to log into ISY and tell it "restore plm" or all of the links will be wrong and that just confuses the issue more. A bad PLM would not prevent your from opening the admin console, so don't blame that on the plm. It would probably be better to boot ISY without any plm rather than the wrong one at this point.

Again, my first thought would be a flaky power supply.

Things are working gradually. I managed to get in to the admin console by using the WAN address. It won't load using the local network address. But I'm making progress here.

By WAN address, do you mean using the portal address? Anyway, that would explain why UD mobile worked, probably you had it configured using the portal rather than a local connection. But if you are logged into the admin console, you can find your LAN ip listed in the settings section and try manually setting those into iox finder as I listed above. Did you set up your isy to have a static address in your router? Iox finder should find your ISY on its own, but if something is going on in your router, your router can block network discovery if configured to do so. I don't know how that would change all by itself, but maybe your router is getting flaky?

This setup had been working flawlessly for the past 10 years. Something must have changed, but I don't yet know what. As I said, I've been able to gradually get it to the point where everything now works except for the ability to log in via the LAN.

Yes, I found the LAN address in the admin console, but it won't open that way. It only opens by using the WAN side IP of my router.

By WAN side of your router, you mean your public Ip address and then you have port forwarding setup? If that works, but being a computer on the same LAN can't see the ISY, then something is wrong with your router.

You could also just ping your ISY from inside the LAN.

Are you sure the computer you are using is on the same LAN? You don't have it on a guest network or some isolated network?

And if your computer is on the same WAN as ISY, and you use WAN:port and have your router set with port forwarding, well that usually doesn't work. You usually can't bounce out of and then back into the same WAN like that. Typically you can only do that from a different WAN. Which would also explain why you aren't seeing ISY on your local connection.

Another test, from your computer that is accessing isy, open a command prompt or powershell prompt and type ping xxx.xxx.xxx.xxx again where xxx.xxx.xxx..xxx is you LAN ip address of ISY. You should see 4 successful pings. If not, then you are either not on the same LAN (or VLAN) as ISY, or your router is doing something to block you.

Yes, it works via port forwarding from the public IP.

Yes, I'm sure its on the same LAN.

As for your suggestion that my computer might be on a different WAN, the answer is no. The MacBook and ISY are both connected to the same LAN. The IoX launcher shows the LAN address of the ISY properly, but I can't click on it to open via the LAN. I have to manually add the WAN address and open it from there.

Yes, I can ping the ISY on the LAN. Port forwarding wouldn't work if I couldn't.

Not sure I agree with the "something is wrong with your router" suggestion. I've got dozens of devices on my network that are all working fine.
