I made this small box to fit my specific purpose to be able to track temperature and humidity in 3 different location (outside greenhouse, inside greenhouse and inside the “winter tent” in the greenhouse). I control a heating fan from Home Assistant, heating in the “winter tent” when the temperature drops. The display and the led is just to see at a quick glance when in the greenhouse. I'm using the Giwnhvx AM2315C I2C (temp and humid sensors). The TTGO has of course ESPHome installed to be able to easily talk to Home Assistant. :)
