Is this an ISY problem?

[Goose66]

I have had a very stable Insteon installation for 2 to 3 years. v1 Thermostat, 2 v1 motion sensors, 3 KPLs, 8 or 9 SwitchLincs, and 8 to 10 light/appliance modules, 4 RAPs. While my previous software/PLC combination was never very stable or very good, the Insteon network itself has always been flawless, at least in the context of the flaws inherent in the system.

 

A week ago I installed a v2 Thermostat and an ISY/99i PRO/PLM combo. While the ISY/99i itself works fairly well (it has some problems loading scenes completely from some devices), now my Insteon installation is starting to flake out a little. I have had two KPL buttons lose connetivity to their loads (at completely random times, not instatntly upon installation of the ISY/99), and one of the motion sensors now only occasionally turns its associated light on and off. I had zero problems with the motion sensor before the ISY/99i and v2 Thermostat. Even weirder, I have an old X10 switched light that I haven't used in years start coming on at random!

 

I know the ISY/99i doesn't have to be operational or present for Insteon scenes to work, but does the PLM? Could a bad PLM be causing the flakyness (or the lack of the PLC in my system?) Does the ISY/99i affect the Remote Access Points at all or reset the topology for these? Has anyone else every had similar problems in conjunction with their ISY/99i?

Is the thermostat a T1700 or T1800 with out a Humidity Sensor?

Check you log as the V2 thermostat adapter has been seen sending random humidity percentages when no sensor is in the T1800 or with a T1700 that can not take a Humidity Sensor. Smarthome and Venstar have a fix for the T1700 have not seen much on the T1800 yet.

[Goose66]

The Thermostat is a T1800 with a humidity sensor installed. While the temperatures and mode status in the ISY/99i for the thermostat always seem to be right, the humidity reading is hit or miss. Do you think the v2.0 thermostat adapter could be flooding my network with bad humidity data?

[Brian H]

Does the log show lots of humidity data being sent?

 

I only have seen messages of users with the V2 module and not having the humidity sensor.

 

What version ISY firmware are you using?

[Goose66]

My ISY/99i throws an error every time I try to view the log. I finally rebooted, now its hardware locked (ERROR light flashing). I think I need another unit. Then I can try to work the Insteon instability problem out.

Hi kingwr,

 

Yes, indeed this is an issue with the unit. It seems like you have file system/SD card error.

 

I already have an email from you to which I am going to respond shortly with instructions for RMA.

 

Sincere apologies for the inconvenience.

 

With kind regards,

Michel
