hey guys,
i am thinking about installing a temp sensor in my bedroom and when i have a virtual switch set to me being asleep, i would like to basically make that temperature replace the reporting temperature for the thermostat - is this possible? maybe not doing it in exactly that way, but possibly another way? i just want to be able to get better control of the temp when i sleep and make sure it doesnt go outside 60-66 degrees fahrenheit. let me know if someone can help. thanks in advance!

So you want to set your thermostat to a certain temp or you want to change what the reading of it is?
Maybe I’m the only one confused but can you clarify what you want a bit better.

the latter - i want to change the temperature it is reading from the sensor built in to the thermostat to the temp sensor in my bedroom - does that make sense? they report different temps so when i am sleeping, i want the thermostat to read from my bedroom rather than the living room.

I thought you might have been asking about that. I don’t think you can use the thermostat screen as your personal display. A z-wave thermostat displays what the sensor is reading and then passes on the information to the z-wave controller.

Trane z-wave thermostate’s (the 500 series) has external temp sensor options (2 extras) so you can use another sensor (located somewhere else) They can adv. the temp or use one or the other sensors (not both). Sounds like this would have worked for you.
Also I have a zone system installed and this also takes care of that problem.
But I think you don’t have the right hardware to do what you need currently.
Other option is to put a temp sensor in the bedroom and use PLEG to heat or cool the house based on that sensor and not the actual thermostat. It won’t display right on the thermostate but it will keep that temp in that room right.
That’s what I’m trying to do - what is the best way to do that?

I would have to research a bit. How about a virtual thermostat. I haven’t looked into those much but sounds like it might be what you need.

Yeah, that does sound like what I would need - I’ll check it out. Thanks!
Not sure if your on ui7 or not but here is an update to the “Smart Virtual Thermostat” plugin.

Again I haven’t used it, but I would check on how it would control your current thermostat and see if it will do what you want.
If you don’t mind replacing the thermostat, I highly suggest you look into the ecobee 3 thermostat with the remote wireless sensors. Works very well using the remote sensors.

If you have a z wave thermostat now you could do this with scenes. Just use the sensor in your bedroom to turn the temp setpoint of the thermostat way up or down to something it will never get to, so basically turning your heat on/off based on what temp you want your bedroom to be. Just add some hysteresis.
Say you want your room 65ish at night. Set a scene to only work when you set your nighttime mode switch and turn the heat on to 80 when the sensor is below 64. Turn it down to 55 when the temp goes above 65. I don’t know how far away the actual temp is in the room with the thermostat so not sure how crazy you need to set the target temps to get the desired effect.

I believe that the solution you’ve proposed would not solve my problem as it would be a one-time thing when i first go to sleep and not allow for any temperature changes as the night progresses - am i wrong?
What temperature changes? I assume when you sleep you want to simply control the temp with the sensor in your room?
If you have two scenes it will turn your heat on/off when the temp is above or below your setpoint. Just have one say if temp is above the desired temp turn the thermostat setpoint way down(off). The second scene would say turn thermostat setpoint way up (on) if the temp is below the desired temp(minus some delta of 1+ degree maybe to keep the cycling down). If you set it to the same exact temperature your heating system will chatter, turn on/off potentially very quickly. Not good for it. When the temp goes above and below the target temp the heat will go off and on respectively all night with those two scenes as many times as it has to to control temperature. Your thermostat will essentially ignore its own sensor since the thermostat will never get to its own setpoint.
I am doing something like this with an outlet that turns on a pipe heater when it gets cold out so my water pipe doesn’t burst. I use outdoor temp instead in my two scenes.
You could go that route as well. Use a controlled ac outlet that powers a relay, or get a z wave device that has a 24vac rated Relay output on it and wire it in parallel with your existing thermostat call for heat.
This scene idea is just to be frugal and use what your own already, if you want to do it right buy a thermostat with the ability to use external temp sensor.
Many systems today have time delays in the thermostats (as well as the condensing units for AC/Heatpumps) to eliminate quick restarts.
A PLEG with the following should work (not tested)
Input Trigger:
SleepMode - Bound to something to indicate you are sleeping (TRUE when in Sleep Mode)
Input Parameter:
ThermTemp - Thermostat Temperature
ThermSetPoint - Thermostat Heating Setpoint
BedroomTemp - The Bedroom Temp
Conditions:
SavedSetpoint - (ThermSetPoint; SleepMode) ? ThermSetPoint : SavedSetpoint
ChangeSetPoint - SleepMode and (BedroomTemp != SavedSetpoint)
RestoreSetPoint - (SavedSetpoint; !SleepMode)
Actions:
ChaneSetpoint - Set Thermostat Heat setpoint to 70
Then in advanced tab … change 70 to:
{(BedroomTemp > SavedSetPoint ? ThermTemp - 1 : ThermTemp + 1)}
RestoreSetpoint - Set Thermostate Heat setpoint to 70
Then in advanced tab … change 70 to:
{(SavedSetpoint)}
