Hardware:
- Freenove ESP32-S3 WROOM
- SHT31 temperature and humidity sensor module (I2C, address 0x44)
- Jumper wires (SDA=GPIO11, SCL=GPIO12)
What it measures:
- Temperature (C or F, configurable)
- Relative humidity (%)
Update interval: 30 seconds (configurable via sht31.interval_s)

Shell command: sht31 - live reading
Config:
"sht31": {
"sda": 11,
