Code

i2c:
  scl: GPIO0
  sda: GPIO2
  scan: true
  id: bus_a
sensor:    
  - platform: sht3xd
    temperature:
      name: "${friendly_name} Temperature"
      filters:
        - offset: -9.9
    humidity:
      name: "${friendly_name} Humidity"
      filters:
        - offset: 21.9

Observations

SHT31 wasn’t that much better than the DHT11, still needed calibrating
Appeared to be mostly placebo upgrade compared to the DHT11 in the other room’s readings
