Did the settings just as in the wiki. No good. I send from a gmail box that only had 3 messages sent in the last week, so definitely not overloading that. It still works from the Outlook client sending-receiving, so the account is good. I went to the Gmail forums and others are reporting issues from other clients, so I don’t think it’s just UDI. I would be checking your setup often as my suspicion is yours will start to fail soon. Google is jacking around with stuff and not admitting to it.

Not sure if something is going on at Google, but was just testing a new notification and found that my Gmail wasn’t working either. Gave the “tls error” message. Tried several changes and no joy. Changed to using the Use Default (not Gmail)and it’s working now. Mine was working with Gmail as late as 2-18-2026.

I was running 4.9.0 up to last week with no problems with Gmail notifications. I moved to 5.3.4 just to be able to add a new siren. I believe the Gmail would still be working with 4.9.0. What is your timeout setting? Mine is at 3000 ms. Seems like I had to change that at one time. SMTP port is 587. Use TLS checked. Use Default unchecked.

For the ISY 994 and gmail, you have to use an App password setup. Google went to two factor authentication that the ISY does not support directly. You have to go to Google and request a specific password that you will then enter in the ISY configuration. Do a Google search for App password Gmail.

I believe that the subscription is only for the Mobilinc Connect portal service, which is as you say required for X but is optional for Pro. Local connection is possible without this. The portal allows remote connection without having to open up firewall ports. I connect remotely by first starting a VPN client on my iPhone to my pfsense router. There are several plug-ins (example: cameras, voice, energy) that are available at extra cost but like the main product have not been updated in several years so I think they are pretty stale by now. That is a concern really for the overall product as well as it has not been updated in many years. It sounds like you are already well on the way to the UD mobile solution which i understand is very capable and well supported, but requires a subscription for at least remote use?

May want to look into Mobilinc Pro in the App Store. It hasn’t been updated in several years, but it is still available. I am using Mobilinc HD (an earlier version) with a ISY994 version 4.9.0. and it is quite stable.

Yeah, i posted there also, but there isn't much activity there anymore. The manual doesn't say much about the different modes and what they do. I did find this: that helps explain a little. Some decent ISY programming tips here: https://homeautomationguru.com/programming-your-insteon-thermostat-with-the-isy-994i/ also. I have been searching, there just ins't much out there.

It's at home and I am at work AtM, but pretty sure the mode is Auto and the fan is Auto. The Mobilinc app has mode options for Auto, Program Auto, Program Heat, Program Cool, Heat and Cool and Off. I don't think the ISY has this many options. I'll have to check and confirm tonight.

I haven't tried at this point to program from the ISY yet. Just using the internal Wake->Leave->Return->Sleep events. It seems to be ignoring them. Almost like the Hold is active, but it isn't indicating that on the display. If I set the heat above ambient, it is heating to that setting (and showing Heating on the display) like it should and then holds that temp.

Just picked up a 2441TH thermostat to play around with. Yeah, i know, it has issues but I have one in my garage controlling and it has been rock solid for years. Trying to understand the various modes. Looks like there is Heat, Cool, Auto, Program Auto, Program Heat, Program Cool, Off. Mostly, what is the difference between Auto, Program Auto, Program Heat and Program Cool? Also, the Hold doesn't seem to work. I push it, but the Hold indicator never comes on. Maybe it just works in certain modes? It seems to so far be ignoring my local programed heat-cool events, but maybe I'm not even in the correct mode. I put it in auto and the set time passes with no changes to the temperature events.

Be aware that the upgrade is not seamless based on the hundreds of posts on here. Just plan the time accordingly. Looks like it depends on the complexity of your install

Yeah, me too. Pretty much the exact same issue. I replaced the PLM and things seemed to be ok, but over the last month or so programs have been steadily getting worse. Programs that used to run great, started getting more and more latency. Motion sensors that used to fire the lights instantly now take a minute or two and then never turn the light off. Checking the event log shows most all devices having 3 of 3 or worst 2 of 3 hops left. Bought a couple of noise filters and installed them in various spots and no better. Next I guess I will try swapping the SD card. The one in there is the original that’s about 10 years old so maybe.

Michel worked on the Java server certs and all is better now.

Ticket opened. Thanks for the replies. I'll post back with the solution.

Yet another one of these. Just doing a search seems to be many of these problems. I can open the iox launcher and it finds my ISY994, but I used to right click and the option to open the admin console will appear. Now nothing. Running 4.9.0 firmware. what I have done: Update Java to latest version. No success cleared java cache: no success deleted all the .state files from the local user account. no success restarted (several times) the ISY994: no success Verified that I could connect to the 994 via a web browser pointed at the IP. Could open the admin console but I hate this interface. Loaded Java on a spare laptop and ran the start.jnlp to open the IOX Finder. It again found the 994 on a search, but same behavior. Manually added an ip to the IOX finder (on both machines) and same results. Running out of ideas here. It worked fine as of about 3 or 4 days ago. No new updates to the computer, although with Windows who can tell for sure. Based on the issue is happening from two computers, it would seem the problem is with the 994. The last time I was in the 994, I did a system backup and it completed successfully. Could it have corrupted something somehow? Everything else, all the programs and scenes etc are operating normally. No error light on the 994. Seems to reboot quickly without issue.
