Sensibo or Cielo Breez AC Controller Not Working

Sensibo and Cielo Breez controllers make mini-split and window AC units smart via IR control. This guide covers common issues with these devices.

Device Won't Connect to WiFi

Initial setup problems:

  • 2.4GHz network: Both brands only support 2.4GHz WiFi
  • Pairing mode: Follow app instructions for putting device in pairing mode
  • Bluetooth setup: Sensibo uses Bluetooth for initial configuration
  • Reset device: Use reset button (pin hole) to factory reset
  • Password: Avoid special characters in WiFi password initially

AC Not Responding to Commands

When commands don't control your AC:

  • IR line of sight: Device must have clear path to AC unit's IR receiver
  • AC model: Select correct AC brand and model in app
  • Manual learn: If auto-detect fails, manually learn remote commands
  • Positioning: Mount device facing AC unit, typically 1-5 meters away
  • Test commands: Use test function in app to verify IR is reaching AC

Temperature Readings Incorrect

Sensor accuracy issues:

  • Placement: Don't mount in direct sunlight or near heat sources
  • Calibration: Some apps allow temperature offset calibration
  • External sensor: Sensibo Air Pro and some Cielo models support external sensors
  • Room vs AC: Understand difference between room temp and AC's internal reading

HomeKit Integration (Sensibo)

For Sensibo with HomeKit:

  • HomeKit code: Find code in Sensibo app under device settings
  • Climate entity: Appears as heater/cooler in Home app
  • Modes: Heat, cool, auto modes available based on your AC's capabilities
  • Automations: Can automate based on temperature, time, or presence

Home Assistant Integration

Local and cloud control with HA:

  • Sensibo integration: Official integration available - needs API key from sensibo.com
  • Cielo: No official integration - may need custom component
  • Climate control: Full HVAC control through climate entity
  • SmartIR: Alternative: use Broadlink + SmartIR for local-only control

Scheduling and Geofencing

Automation features:

  • Schedules: Set up time-based schedules in respective apps
  • Geofence: Enable location access for presence-based automation
  • Climate React: Sensibo's feature to maintain temperature range automatically
  • Usage reports: Both apps provide energy usage estimates
