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

Thanks Indymike for the tips and comments. I’ll do some more testing in the near future, but for now after spending the last few months getting reliability back into it I think I will just bask in the glow of success for awhile.

I may have not been very clear in my explanation. The PLM and the EZIO were plugged in directly to the wall outlet. Everything else were plugged into the UPS which was plugged into the wall through the filterlinc (filtered). This setup worked well for 10 years. My original (recapped) PLM failed about 3 months ago (all on events, programs not running) so I replaced it and at first it worked well. Then after a week or two programs started failing until eventually they wouldn't run at all. This is when I thought it may be noise like from the ceiling fan. I went through the breaker box breaker by breaker trying to isolate the noise with no luck. I never shut off the power to the wiring closet as that would have killed the PLM too. Then I moved the PLM and ISY 994 to another outlet and Bam, it instantly just worked. So the noise (or signal sucker) is coming from something in the wiring closet but nothing has changed in there in over a year (added a fiber optic ONT). I will add that my test method was to run the "then" part of the If-Then-Else statements in programs and identified certain programs-devices that were especially trouble prone. Many times the program would run and the progress bar would appear and cycle through several times and eventually fail with a "couldn't connect to device etc" and then the device would have an exclamation mark next to it. If I then did a query on the device it would sometimes clear it and sometimes stay with the exclamation mark. Hops would vary from no hops (3-3) to 3-0. This is I think a classic example of noise. Now when I do the same thing there is no progress bar and it instantly responds. The last thing to add is that the new PLM, V2.7, seems to have very poor RF performance. When trying to link to motion sensors it just would not connect, even with the motion sensor laying directly on top of it. I then took the same motion sensor and placed it next to an 2443 access point and it connects perfectly. I guess I am replying back to add to the forum info database as noise seems to be a big issue and to ask if the filterlincs ever fail and start letting noise through. It looks like no to that.

Turns out like most of these issues the ceiling fan was a red herring. The true fix was having to move the 994 and PLM to another location due to noise in the location that had worked previously for 10+ years. It is now physically a foot away from the electrical panels in the garage and is rock solid in reliability and most all hops are now 3-3. A few 3-2’s but still very reliable. I wish I could get it to work where it was (network wiring closet, about 10 feet from the panels) but there are so many devices in there tracing down the noise maker may be impossible. I had most everything there, except for the PLM and a ezio 2x4, plugged into a UPS and it was plugged into a filterlinc. Do those ever go bad and start letting noise through?

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.

Thanks Paul. I may have jumped the gun a bit. Doing some more in-depth analysis on this at the admin console by running the then statements on the off-at-sunrise and on-at sunset programs and it still isn't consistent, even with the ceiling fan off. Going through the breakers one at a time trying to isolate the noise, if it is in fact a noise issue after all. Thought I had it narrowed down to bedroom 2 by flipping the breaker off, but on about the 20th cycle if the then statements it reappeared that one of the outside lights didn't respond correctly. Very tedious and I am getting my walk time in going back and forth to the switch panel!

Been seeing issues with programs not running at all or partially. An example is a program the turns outside lights off at sunrise. This morning while in bed I checked on Mobilelinc and sure enough the lights were still on. Tried manually running the then statement in the program and no luck. Tried several times. Then noticed the ceiling fan running. I remembered that motors can cause noise on the power line. Shut it off and tried the then statement again it ran perfectly. Lights went off. Now the question. How to filter the noise on hardwired fans? The outside lights are controlled by 2466SW togglelincs so no RF, but have been rock solid for years and still work fine when directly controlled through the admin program or Mobilinc or at the switch so I think they are ok. It’s just the ISY 994 programs. I did have to replace the PLM a couple of months ago. One other thing. The ceiling fan has a Hunter remote control setup installed. In the ceiling mount. Is that a known cause of noise?

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.

Mobilinc works ok for me via VPN, but device states are not always correct. A device will show off when in fact it is on. A forced refresh fixes it. Need to look at UD mobile but that takes minimum 5.0? I’m on 4.9. Sent from my iPhone using Tapatalk
