I've been working on a remote node that will measure temp/humidity and display 'alerts' from the main machine. It uses a Raspberry Pico WH and connects to the Ficus Webapp to sync time and temperature data currently. It has a AHT21 I2C IIC High Precision Digital Temperature and Humidity Sensor Module and a 0.96 Inch OLED I2C IIC Display Module 12864 128x64 Pixel SSD1306 Mini Self-Luminous OLED Screen for local display. I added a piezo buzzer for audible notifications. I intend to eventually extend the software to let it display notifications from the main computer.
