“This temperature corresponds to 0 degrees Fahrenheit, so it was “probably a round, easy number to remember”

That’s what Allouche and team will be working on next, as they build their research summary into a full report, to be published in September 2024. “These findings give good reasons for ‘3 degrees of change’ to be further explored,” Allouche says.

    To be clear, the heatermeter isn’t my project; I’m just assembling one. I’ve got most of it soldered; I just need to 3D-print the case, add the LEDs (which need the case for proper alignment), install the software on an SD card, and then fire it up and see if it works.

    Then, for the freezer-logging idea, I’d need to figure out how to log the data it provides and correlate it with the data from one of my ESPHome-flashed Sonoff S31s. I might see if I can get Home Assistant to do it, since I want to integrate my thermometer with it anyway so it can do stuff like flash a light when it’s time for me to go outside and stoke the fire in my offset smoker.

      The freezer has a far simpler ready-made solution, an Acurite or Lacrosse outdoor sensor ($10-20), an RTLSDR dongle ($10) and rtl_433 to put the data on MQTT.

      I do my data logging with the free version of Mango Automation SCADA which integrates very well with MQTT and is lightweight and cross platform.

      Got a sensor in each of my freezers and my root cellar, rtl_433 also picks up my weather station and rain gauge, wireless buttons, motion sensors and more, rtl_433 is a great addition to any home automation system and cheap and easy to set up.
