Setting variable from sensor attirbute and sending as push notification

SmartApps & Automations webCoRE

Hi,

I want to create a variable from a sensor attribute and then send it with a push notification.
my piston has 2 actions:

  1. “save attribute to variable” shows as:
    Save attribute ‘calling’ to variable {calling}
  2. “send push notification” shows as:
    Send Push notification ‘Test {calling}’

But all I receive as notification is ‘Test’

I don’t know if I have to define variable calling elsewhere.
Can anyone please tell me where am I doing wrong ?
what’s missing ?

thx

I use a Basic CoRE Piston with a SmartThings contact switch that has a temperature attribute. The contact monitors the temperature of our hot tub mechanicals area, mostly in the winter time & when we travel, to ensure the hot tub is online and staying heated. I also grab the outside weather using the AccuWeather SmartApp for comparison.

One could either set a CoRE timer to fire every 5 minutes or use the condition of “changes” which will send a reading value at every different temperature level and then route the digital output as I do below to an email, notification or as a SMS text as below.

CoRE Piston

IF
● Hot Tub Temp temperature changes
THEN...
Using Hot Tub Temp...
► Save attribute 'temperature' to variable {temperature}'
Using AccuWeather (45385)...
► Save attribute 'temperature' to variable {outside_temp}'
Using location...
► Send SMS notification 'Hot Tub Inside Mechanicals temperature is {temperature}°F and outside temperature is {outside_temp}°F' to 555-555-5555

SMS Message Log

Hot Tub Inside Mechanicals temperature is 69°F and outside temperature is 37°F
Hot Tub Inside Mechanicals temperature is 68°F and outside temperature is 36°F
Hot Tub Inside Mechanicals temperature is 67°F and outside temperature is 36°F
Hot Tub Inside Mechanicals temperature is 66°F and outside temperature is 35°F
Hot Tub Inside Mechanicals temperature is 65°F and outside temperature is 33°F

Thanks for your reply.

Actually when I entered “First” as the aggregate parameter , the notification became correct (shows the value of parameter)

Is this parameter , a mandatory one ?

I use Last, which I think sends the LAST value read by the sensor!.

CoRE Example - Setting Variable From Sensor and Sending Push Notification

In this example, I use the ‘bulbEval’ variable to capture the true/false evaluation result of a bulb. It could easily be a sensor too.

Piston Mode: Basic

Requires:
1 device

And you set the variable ‘bulbEval’ to capture the state:
