Posted September 29, 20187 yr Hi - I have a CT100 z-wave thermostat. It has the "C" wire and I confirmed that it runs without batteries installed. I included it into the ISY994i/IR Pro with the z-wave dongle. Did a Sync and heal and the thermostat shows up fine. However, if I change any parameter like Heat or Cool setpoint, the parameter does'nt change until I hit the query button. This isn't good as I am using eKeypad Pro on my iphone and when I change a parameter, I have to go to the ISY console an hit query for it to take. Any ideas? Thanks!
September 29, 20187 yr Author I should add that the parameter on the thermostat itself does change. The issue is that the ISY doesn't show the change until a query is performed.

The issue is that the ISY doesn't show the change until a query is performed. I have a CT100 and it works the same way. This is because the CT100 does not have the instant status update feature. You could have a program in ISY to query the thermostat every so often, so you have the correct status.
September 29, 20187 yr Author Thank you! I'm new to z-wave and I didn't realize that there was a feature called "instant status update". Do you know of a good thermostat with that feature? Thanks again.
September 29, 20187 yr @cwagner2401 , I'm sure there are z-wave thermostats that have instant updating, I'm just not aware of them. I have three z-wave thermostats and none support instant updates. It's not been a huge deal for me. However, I know it is for some.
November 11, 20186 yr I see the same thing, but I am able to do a query from my smartphone via the MobiLinc app (via the little circular arrows button). I also wanted to monitor the thermostat sensed temperature in a program, so I wrote a program to query the thermostat every four hours. Crude, but it works. Similar issue with the sensed temperature on my Aeotec water leak detector (and probably most battery-powered Z-wave devices).
November 10, 20195 yr I got three of these thermostat's still in their boxes. Let me just confirm: The ISY will not be aware of the running status & the temperature until queried?

If the ones you have do not support instant status then this would still apply.

November 11, 20195 yr I have the GoControl Z-Wave thermostats running on batteries that work just fine, show instant status etc. I'm also using Honeywell Z-Wave thermostats powered by the C wire, both models work fine with the ISY setup.

Which model Honeywell do you have?
