I have a multi-zone heat pump HVAC system. One heat pump, three thermostats. Each thermostat controls dampers for different parts of the house.
Thermostats are Honeywell Vision Pro 8000 Wi-Fi. Honeywell TCC connects to SmartThings. All good. Except…
The thermostats act like they’re controlling 3 independent units. So they can be changed to conflicting settings, like heat in one zone and cool in another.
I need some ideas how I could build something in SmartThings that would let me change heat/cool/off mode on all three thermostats with a single tap.
I’m total noob to SmartThings programming but I’m a retired software developer. Just need a jump start to get going in the right direction.
And in either case, The following FAQ should give you a jumpstart (this is a clickable link)
(This is a wiki post: feel free to edit it or add to it as needed. Also, I can’t take any screenshots since I can’t use the app at this time due to its incompatibility with voiceover, so feel free to add screenshots where they would be helpful.)
At one point, one of the biggest advantages of using the SmartThings platform was the wide variety of devices that it supported. However, by the end of 2017 several competing platforms had caught up in that regard.
Where SmartThings still holds a significant advantage over some of the other low-cost home automation solutions is in the ability to really build really complex rules in a fairly simple manner. You won’t have to be a programmer, but you may need the help of other community members to get the logic constructed just right.
So how can…
Hi, there is already a smartapp for that… It’s called
ScheduleTstatZones and it’s designed to manage multiple thermostats with the concepts of rooms/zones/schedules…
You elect one thermostat as the master and you can specify all the slave thermostats in your rooms/zones to be controlled…, And you can control each of your zones with virtual zone devices (using a single tap).
I’ve just released a new version:
Just to let my contributors and all ST users know and all users who would like to do targeted heating/cooling in their home that I have new versions of my zoned Heating/Cooling smartapps available at my store :
I made a small change to ScheduleTstatZones (v8.3), and to correct the zone’s active flag when set using the virtual zone devices.
Also, in ScheduleTstatZones (v8.3), you can now indicate in each schedule if you want to synch the rooms’ slave thermostats (ex. eTRVs, portable heaters/coolers, mini/window splits) with the master’s thermostat’s setpoints or use the corresponding scheduled setpoints.
You can download the new versions at my store using the original sellfy link.
The new code is available at my store.
Refer to the ST community wiki for more details about the features and use cases supported (under the supported features and configuration sections):
P.S. The smartapp has many features and to do something similar with webcore would be impossible (more than 4500 lines of code).
