shannong Posted January 20, 2014 Posted January 20, 2014 I have a 2441ZTH v.0D that is running on an external power supply with ISY 4.1.2 & PLM 2413S v.9B. I've noticed updates are not sent in real time but rather every 60 seconds. Not a big deal but annoying. Not wanting to wait, I queried the tsat to immediately update the current temp to test a program I had just written. The temp did not update. I opened the event viewer and queried it again. I saw all the fields returned except for current temp. I've tried multiple times with no ST value returned. Does the 2441ZTH send temp updates for others with this tstat in ISY? I'd opened a case with Smartlabs but decided to start here since I figured their first response would be "It's probably something wrong with your network or controller". Any thoughts or assistance is appreciated.
Michel Kohanim Posted January 21, 2014 Posted January 21, 2014 Hi shannong, Please post the whole contents of the event viewer using Level 3. In short, it should. With kind regards, Michel
Michel Kohanim Posted January 21, 2014 Posted January 21, 2014 Hi shannong, I am so very sorry ... just looked at the code and temperature can NOT be queried on Z models. The first command queries set points The second command queries modes The third command (if NOT ZTH) would have queried the temperature With kind regards, Michel

kaphely Posted January 21, 2014 Posted January 21, 2014 Hi, just a question as I plan to buy a 2441ZTH soon. Even if the current temp cannot be quieried, will it still be sent to the Isy every 60 seconds (as Shannong is mentionning) so I can know what is the current temperature using mobilinc for example? What are the nodes that get created in the Isy for the 2441ZTH? Thank you

What are the nodes that get created in the Isy for the 2441ZTH? Thank you It only sends update every 15 minutes when running on batteries and every minute when running on an external power supply (purchased separately). It's also important to note that the temp is not sent every 60 seconds. It's sent every 60 second IF there's been a change. If you're on batteries, then it's the same behavior but every 15 min. If you previous change message was lost on your Insteon network then for some reason and since you can't query you won't get another update until there's another change. Currently where I'm at the day temperatures are relatively stable and close to the desired temperature in your home. Mine goes hours without sending any temp updates and I can't query it. I do not recommend this product.
kaphely Posted January 21, 2014 Posted January 21, 2014 OK Thanks for the info. Can someone tell me if the Wired version (2441TH) behaves the same? Can the temp be queried on the wired version? What are the available nodes that appear in the Isy when the 2441ZTH is added? What about the 2441TH? Also, is there a reason why the temperature cannot be queried? Or is it just a bug in the current Isy code? Thank you

Same nodes for TH and ZTH. Thermostat - Main. Responder only. Modes, set points, etc. Heat Controller. Controller only when heat is active. Cool Controller. Controller only when coolInc is active. According to Michel's post above Smartlabs failed to add the capability to query the temp.
shannong Posted January 21, 2014 Author Posted January 21, 2014 Beware that If you have a gas furnace with electric igniter there is a pervasive issue with voltage spikes creating unexpected behaviors on the TH.
kaphely Posted January 21, 2014 Posted January 21, 2014 Thermostat - Main. Responder only. Modes, set points, etc. Does that mean I cannot change the set points from the Isy? My goal is to use the thermostat to control my pool heater (with a mod using the remote temperature probe), and the point is to be able to remotely, from work for example, set the temperature set point higher so the pool is warm when I get home. I also want to create programs that will change the set point using a schedule. So can you confirm if I can set the heat set point from the isy? Because if not, my idea just died Thanks for the help.

You can change the set points of the TH from ISY with schedules or programs.
kaphely Posted January 21, 2014 Posted January 21, 2014 You can change the set points of the TH from ISY with schedules or programs. Is this also true for the ZTH?
shannong Posted January 21, 2014 Author Posted January 21, 2014 You can change the set points of the TH from ISY with schedules or programs. Is this also true for the ZTH? Yes you can change the set points of the ZTH from ISY but that's more for visual feedback since the ZTH doesn't actually control anything on it's own. Changing the set point of the ZTH will be reflected on its display but no action since it's not wired to anything. For the ZTH you'd be doing this in reverse. You would change the set point on the ZTH which would send an update to ISY where the ISY would take an action such as changing the set point of the TH which is wired to the pool equipment or controlling some other external device can is interfaced to your pool equipment. You cannot control the Fan settings of the ZTH from ISY but the ISY will see changes to the Fan state performed on locally on the ZTH.
kaphely Posted January 21, 2014 Posted January 21, 2014 I did not plan on using any TH thermostat, just a ZTH stand alone. My idea was to create a scene with the ZTH Heat node as the controller and an IOLinc Relay as the responder. The Heat Node of the ZTH would trigger the iolinc relay when the temperature measured by the ZTH is below the ZTH set point. Are you saying this is not possible? Thanks for all your answers.

Would you be using the external temp sensor capability of the ZTH in this situation?
shannong Posted January 21, 2014 Author Posted January 21, 2014 I just had a chat session with Smarthome. That tech claims to have performed a query to the ZTH from an ISY and received temp updates (ST message). Michel - Can the ISY take a closer look?
kaphely Posted January 21, 2014 Posted January 21, 2014 Would you be using the external temp sensor capability of the ZTH in this situation? Yes and no. Actually, i would use the remote temp probe but I would modify the thermostat to use the remote probe as it's main sensor. This mod has done done and shown here on this forum.

This should work fine for you assuming the temp probe is functional. The ZTH would relay current temp and any set points to ISY. Via programs or scenes the ISY could trigger the IOLinc for the heater. The ISY could push Set Point changes back to the ZTH via programs or schedules if desired. Strictly speaking, the ZTH isn't a thermostat in this scenario since it controls nothing. It's really just a temp sensor and remote control. The ISY acts as the thermostat deciding when to turn things on/off based on current temps and even telling the ZTH what it's Set Point is sometimes. In summary, I don't see any issues with this scenario using the ZTH and ISY.
kaphely Posted January 22, 2014 Posted January 22, 2014 glad to see my idea will probably work. I just don't get the why ZTH has a Heat Controller node, that is on when heat is active, if you say it cannot control anything. Won't this node be on when the temp reaches a lower level than the set point? I am asking a lot of questions as I am just trying to fully understand how this thing works to make sure I buy the right thing. I don't want to order it and then have to return it with a restocking fee if it will noit do what I want. I'm really thankful for your help by the way. It is nice to get feedbakc from somebody who actually already own the thing!

It is nice to get feedbakc from somebody who actually already own the thing! It was designed to be cross-linked directly with a TH that is wired to the HVAC. The ZTH is linked to the TH and one of them is Master at any one time depending on which tstat you want to be the primary decider of when to engage the HVAC system. Changing set point on whichever is Master changes the set point on the other. For example, the TH might be the Master during the day but when you go to sleep the ZTH in your bedroom is turned to Master to control based on the local temp in there and make set point changes from your bedroom. The idea is the programming and remote control are built into the units vs programming all of that logic on an HA controller like ISY to create multi-zone control over a wireless network but still allow HA integration if desired.
66splitbus Posted January 31, 2014 Posted January 31, 2014 Dang, got the 2441ZTH and just found out I can load the temperature value into a variable- at least I dont think I can. I was hoping to get the room temp and the water temp of my aquarium and just have them as updating variables to use. It looks like I need to get the wired thermostat to do that but its $150! Any other cheaper solution out there or a way to get the ZTH working?
shannong Posted January 31, 2014 Author Posted January 31, 2014 You can load the current temp into a variable. See this post. http://forum.universal-devices.com/viewtopic.php?p=101566#p101566 I had something similar setup and working but I finally dumped my ZTH. Keep in mind the tstat reports in 0.5F increments and the ISY currently only support integers until v5.x in a few months. That means when the current temp is report as x.5F it won't match any programs and no actions will occur.
66splitbus Posted February 1, 2014 Posted February 1, 2014 Wow, I wondered if that would work when I saw the pull down with all the temps! crazy crazy crazy.
