my indoor thermometer (currently sat on my my home office desk), i used to sort out the Arduino cloud configs before upgrading the main weather station
uses
Arduino Nano ESP32
Adafruit DHT20 I2C temp, humidity sensor
Adafruit ST7789 SPI 2" TFT display
got to add a clock display to the screen then make a more permanent stripboard circuit and 3d print a tidy housing for it
you can see the way the temp drops when the heating shuts off at 10pm and then rises again when it comes back on at 6am
