dba62 Posted December 3, 2017 Share Posted December 3, 2017 The thermostat is the 2441TH. This is a relatively new phenomenon, but it appears that the ISY is often not in sync with the thermostat. For instance, currently the Temperature is 70 and the Heat set point is 70, but the ISY thinks the current temp is 66 and the set point is 64. Any ideas? Thanks. Link to comment
dba62 Posted December 3, 2017 Author Share Posted December 3, 2017 Oops - I just thought of an important detail that I left out. I recently replaced my PLM as it died. Link to comment

dba62 Posted December 4, 2017 Author Share Posted December 4, 2017 Hi dba62, Please make sure you follow the instructions here http://wiki.universal-devices.com/index.php?title=INSTEON_Safe_Mode_Dialog With kind regards, Michel Hi, I did all of this. All of my other insteon devices are working normally. The only issue I have is the thermostat. Thanks. Link to comment
Michel Kohanim Posted December 4, 2017 Share Posted December 4, 2017 Hi dba62, Is this a battery operated thermostat? If so, it's not going to send status updates. With kind regards, Michel Link to comment
ScottAvery Posted December 4, 2017 Share Posted December 4, 2017 Compare link tables? May still be tied to old PLM. Link to comment
dba62 Posted December 9, 2017 Author Share Posted December 9, 2017 Hi dba62, Is this a battery operated thermostat? If so, it's not going to send status updates. With kind regards, Michel No. The thermostat is not battery powered. Link to comment
dba62 Posted December 9, 2017 Author Share Posted December 9, 2017 Compare link tables? May still be tied to old PLM. How do I do this? I should also add that control of the thermostat works fine (I have a program running which sets the temperature to different values at different times of the day). Link to comment
HAMILD15 Posted December 10, 2017 Share Posted December 10, 2017 I had the same problem (Thermostat = 69, ISY=65, recently replaced PLM, motion control sensors to change thermostat temps based on room occupancy)... For the last several days, my ISY was showing 0 degrees but programs appeared to all work properly.... SOLUTION . . . I “restored” the Thermostat (right mouse click in ISY) and then sent updates to the device... it has been 12 hours and they remain sychronized... Link to comment
HAMILD15 Posted December 15, 2017 Share Posted December 15, 2017 DBA62... do you still have this problem... the fix I had (restoring device) worked for about 3 days and is now reoccurring. Link to comment
ScottAvery Posted December 15, 2017 Share Posted December 15, 2017 How do I do this? I should also add that control of the thermostat works fine (I have a program running which sets the temperature to different values at different times of the day). I can't see my console from here, so I can't give you the exact steps, but you can see link tables by right clicking the device in the admin console. Probably under the diagnostics menu when the right click context menu pops up. If you have done a restore they should be identical. Checking to see if it is orphaned from the PLM is a little more tedious - you have to find the common single link that all the other devices have, which will be the PLM link, and make sure your troublesome device also has that link. If not, that device has to be removed and re-added. As for intermittent failures to update status, note that even the hard wired Insteon thermostat model is wireless-only because it is powered by a 5-30v transformer in the furnace, not the power line. That means you could potentially just have a communications issue. Move a dual band device or two near it for a while to check that. Link to comment
LFMc Posted December 15, 2017 Share Posted December 15, 2017 I am having exactly the same problem. Just replaced my PLM a month ago and both my powered thermostats are not reporting correct temps or status to the isy unless I query them. I'll try restoring them.

ScottAvery Posted December 15, 2017 Share Posted December 15, 2017 I am wondering now if perhaps thermostats are secure devices that require special treatment in some way, like the morninglinc lock controller. Link to comment

ScottAvery Posted December 15, 2017 Share Posted December 15, 2017 Nothing in my experience leads me to think that they are. Sent from my XT1575 using Tapatalk In which case I still recommend checking to make sure the devices are indeed pointing to the new PLM. Removing, resetting, and adding them back would be the quickest thing, but you can manually inspect the links as mentioned above. Link to comment
