SMS (text message) Notification of Too Cold in my Home
January 10, 2019
My weather display, based on a Raspberry Pi Zero-W, sends temperature data to a ThingSpeak (thingspeak.com) channel. A device in the basement, based on an Arduino UNO, sends temperature data to a different ThingSpeak channel.
I have an event on If This Then That (ifttt.com) that will send me a text message if either of these values are below 50 degrees F.
To connect the two, I created a “React” App on ThingSpeak that runs whenever data is inserted in the channel and triggers an applet on ifttt to actually send the SMS message.
