Variables for Thermostats

UD Team,

 

I'm happy to see in 4.0.1 that we can start to get some functionality around comparing thermostat temperatures. I'm still waiting for the day I can truly compare by using variables & math.

 

A room drops temperature faster than others. I have a battery powered 2Gig CT100 in there just to report temp. I'd just like to compare and trigger if it drops below a certain delta to other rooms. I've got a fix for it during heating season but it's a bit clunky.

 

If
       Status  'Thermostats / Amanda's Thermostat' is 62° (Temperature )
    Or Status  'Thermostats / Amanda's Thermostat' is 61° (Temperature )
    Or Status  'Thermostats / Amanda's Thermostat' is 60° (Temperature )
    Or Status  'Thermostats / Amanda's Thermostat' is 63° (Temperature )
   And (
            Status  'Thermostats / Third Floor Thermostat' is 65° (Temperature )
         Or Status  'Thermostats / Third Floor Thermostat' is 66° (Temperature )
         Or Status  'Thermostats / Third Floor Thermostat' is 67° (Temperature )
       )
   And $Kids_Here is not 0
   And From    11:00:00PM
       To       5:00:00AM (next day)

Then
       Set 'Thermostats / Third Floor Thermostat' 68° (Heat Setpoint)
       Wait  30 minutes 
       Set 'Thermostats / Third Floor Thermostat' 65° (Heat Setpoint)
       Set 'Thermostats / Third Floor Thermostat' Fan On
       Wait  5 minutes 
       Set 'Thermostats / Third Floor Thermostat' Fan Auto

Else
  - No Actions - (To add one, press 'Action')

 

Would love to be able to just check the delta rather than specific temp readings.

Well this is timely!

 

I've just spent an evening trying to figure out how to read a stat's setting and push it into a variable, and I'll ultimately also need to do it the other way around. This is key to my plans for a heating management system for the house, as I have a 6-zone hydronic heating system and want to monitor open/close status for doors that separate the zones, and align the setpoints for stats in zones that have an open door between.
