    I’m thinking that the /u is for the UWP mounting system.

    The 2007 has the SmartStart but I don’t think it explains the “/u”

    “Model TH6320ZW2007: Same as TH6320ZW2003 but TH6320ZW2007 has SmartStart”

    is it this SmartStart they advertise?

    A new Z-Wave feature called SmartStart will make it easier than ever to enroll smart devices into a home-automation system for instant interoperability and control.

    I found the TH6320ZW2007 on Amazon
    https://www.amazon.com/Honeywell-Hom.../dp/B0BHTQF8NL

    Does anyone know what the /U (TH6320ZW2007/U) represents?

    Thanks!

    I have 6 of the TH6320ZW2003 (Firmware 1.4.9, zwave 4.61) but I'm not seeing the flood of humidity reports. I'm on battery (no c wire) so that might be a difference BUT I can change the "Z-Wave Humidity resolution" both on the menu of the thermostat and by adjusting the zwave parameter 45.

    By the menu - Menu, Zwave Setup, Hum Report, and then adjusting between 1% and 5%

    If I retrieve parameter 45 on the root device I see the corresponding change (1 thru 5)

    Looking at the z-wave alliance site I see that parameters 44 and 45 were added for the TH6320ZW2007 but they must have also been added to an updated firmware version of the 2003 device ​

    Hi there --
    Certainly appreciate your information regarding the 2003 vs 2007 Honeywell T6 Thermostat models.
    I had to turn off logging on my 2003 models as the humidity was being recorded several times a minute reflecting the sensitivity of the humidity sensor. Your advice regarding the 2007 model prompted me to buy them as replacements to the 2003.

    I just installed the 2007 model with software / firmware as referenced above. It's doing the same thing -- at least for the first hour of install. In the manual, I noted that ISU 1426 says that you can adjust the humidity reporting threshold -- (i'd set it to 10%) - there's no place to set it on the thermostat itself and I'm not seeing any parameters in my HS4 Zwave configuration screens. If I knew the parameter number and size, i could set it manually. But I don't have the parameter number. The ISU is defaulting to 1%.

    I'm not using the secured mode.

    Any suggestions?
    thanks so much

    Thanks for this info -- wish I knew this when diagnosing with Honeywell who ended up replacing all 3 thermostats with what looks like the same one (version 4.61 (ZDK 6.71.1) but with upgraded firmware from the original. They never even mentioned this other model an I worked with them for over a month on the issue. wow. Yep -- can't seem to find the 2007 version. Will have to keep an eye out for it. thanks again!!

    Avoid the Z-Wave 500 series T6 - TH6320ZW2003 - https://products.z-wavealliance.org/products/2893
    If you can find the 700 series T6 - buy that - TH6320ZW2007 - https://products.z-wavealliance.org/products/4620

    The 500 series version is way too chatty and sends temperature and/or humidity reports way too often. If you're running it on batteries it may run out in a few months depending on the environment. If powered via the C-Wire, it tends to clog up the network with several reports every minute which may make setting the temperature less reliable.
    The 700 series version is much better and only reports when there is a significant change, automatically requests the date/time so you don't have to enter it by hand, has longer RF range (and lower power) since it's using the newer Z-Wave chip.
    The 500 series version struggles with Security S2 when the hub is Z/IP Gateway based (which Homeseer is not so it's OK).
    I recommend joining them non-secure either way as you really don't need the Z-Wave encrypted in most cases.

    Yes they are reliable and I think the 24v is what gives it so much strength in zwave range. I just wished that a notice would appear in the HS device icon to tell notify me of filter alerts as I never look at the thermostat itself anymore.

    Thanks so much for the reply.
    Originally, I had deleted the Humidity z-wave node to make it shut up, but then the system started reporting "missing node" errors in the log every time the thermostat sensed a humidity change. So I rescanned the thermostat and just turned the Humidity logging function off. Like you, I have not had a problem since and still consider this one of my most reliable devices.

    Hi - yes -- the Honeywell thermostats have been rock solid here as well. They are nice units - agreed. Verbose humidity reporting is a flaw and Honeywell sent replacement thermostats under warranty with upgraded firmware (apparently the ones I got had older versions). I've had Humidity Logging turned off, and I just turned it back on for one of my units and yes, it's still reporting humidity changes every several minutes -- back and forth from 33% to 34% within several munites. There's no setting to adjust the sensitivity. So, I just keep logging turned off. I argued profusely with Honeywell that there should be an adjustment to sensitivity and reporting File Save Error in 1.1.12 but it's not available on these units. The current version is: 4.61 (ZDK 6.71.1), Firmware 1.3. Hope this helps.

    Airtog - Did you eventually succeed with your Humidity issue? My Honeywell thermostat has been rock-solid for over a year now, but the humidity issue still nags when I think about it.

    Good to see finding some success with this.

    I initially had the "Do not Log" box under the humidity feature checked. This cleared up my log spamming issue. Unfortunately, I'm running Homebridge with the Homeseer plugin and logs continued to inundate through that service.

    Living in the SE Texas, I have no need to monitor and/or manipulate the humidity in my home. I have a very rudimentary knowledge of Homeseer and zwave, so I had to settle for a simple overkill solution. I ended up just deleting the humidity zwave feature from my Honeywell thermostat. It fixed my problems, but I really hate solving issues like this with a sledge hammer.

    POST SCRIPT UPDATE:

    In further testing, it appears that polling only impacts reporting - not thermostat actions based on temperature changes. Temperature / humidity change reporting back to the Zwave controller effected and if there are events etc that are triggered by such change, they will be impacted with delayed reporting.
