Trigger and notification

Hello,
My weather project works perfectly.
I would like to improve it by adding an action ( if possible, in app) to the setting of a temperature value, ie I would like to send a push notification (or sms, email, whatsapp, pigeon :)) when the temperature indicated in the gauge is 30 °, is it possible?

Thank you
Fabio
