Thermostat temperature different than captured variable

[jmpnjimbob]

I am using an Insteon 2441TH  thermostat in my system. The readout on the screen is showing a temperature reading that is a couple of degrees warmer than the reading that my variable shows on my ISY console screen. How can this be?

I'm creating a program to trigger an action when a certain temperature is met. If my thermostat is showing one thing and my variable another things might not work the way I'd like.

This is how I am capture the temperature reading to a variable.

If
        'Thermostat' Temperature < 150.0°
 
Then
        $Inside_Temp  = 'Thermostat' Temperature °
 
Else
   - No Actions - (To add one, press 'Action')

Is there more to this that I need to do?

These Insteon stats don't send updates on changes less than about 1.5 degrees C or about 2+ degrees F.

IIRC if you force a change at the stat locally to some setting it will update the temperature with the status change.

Thanks Larry. So seeing a 2 degree difference in my variable and my indicated temperature might not be anything to worry about. 

While I'm on this topic, are there other thermostats that might do a better job? My worry is that if I don't go with an Insteon device their integration might not be as smooth and easy especially for a novice.

The other thing to look for is a little ‘leaf’ symbol on the screen. That means the stat is in set back mode.

 

I gave up on mine after SmartHome replaced it twice because it randomly went into that mode.... and moved to a zwave stat. It’s been stable since.
