Agave not controlling Honeywell ZWave thermostats

[jdm5]

Hey James and community,

Looking for some help - I purchased Agave recently and really like it so far.  Everything seems to be working except (2) Honeywell TH8320ZW1000 thermostats (ZWave).

The ISY running 5.3.1 sees and controls them fine; running latest Agave on IOS / iPhone.

Agave sees the thermostats, but pushing temperature up/down in IOS doesn't seem to do anything.

Making temperature changes in ISY _IS_ reflected in Agave.

Any thoughts/suggestions on what might cause this or how to troubleshoot?

Thanks!
