Question 1

device feels really hot to the touch on the top, is that normal or dangerous?

Accepted Answer

DIAGNOSIS Mild warmth is normal. The Breez Plus contains a small computer that generates heat. Excessive heat indicates a ventilation problem or potential fault. FIX First, ensure proper installation. The unit must be plugged into a vertical wall outlet. Do not use a loose power strip or an outlet behind furniture. There must be at least 4 inches of clear space above and around the side vents for airflow. Second, check the ambient temperature. If the room is above 95°F (35°C), the device will run hotter. Third, touch-test. It should be warm, not hot enough to cause discomfort or a burning sensation within 2 seconds of contact. IF THAT DIDN'T WORK If it is excessively hot and the display shows erratic behavior, unplug it immediately. A faulty power adapter or internal component can overheat. Let it cool for one hour. Plug it into a different, known-good wall outlet. If the overheating repeats, discontinue use and contact support. HEADS UP Never place objects on top of the Breez Plus. Do not install it in direct sunlight. The operating temperature range is 32°F to 122°F (0°C to 50°C). Sustained operation at the high end of this range will cause noticeable heat.

Question 2

my ac turns on but the breez plus can't change the fan speed, it just stays on auto

Accepted Answer

DIAGNOSIS The IR command set for your specific AC model is incomplete or the AC is in a mode that locks fan control. FIX First, check the current operating mode. Many AC units lock fan speed to 'Auto' when in 'Dry' or 'Energy Saver' mode. Use the Breez Plus or app to switch the mode to 'Cool' or 'Fan'. Then attempt to change the fan speed. Second, verify the IR code set. In the Cielo Home app, go to Settings > AC Settings. Your AC's model number is listed. If it says 'Generic' or a similar model, the code library may lack granular control. IF THAT DIDN'T WORK Manually re-teach the fan speed commands. In the app, go to Settings > AC Settings > Change AC. Select 'Custom AC'. Follow the prompts to 'Learn' commands directly from your AC's original remote. Specifically teach the Power, Mode, Temperature Up/Down, and each distinct Fan Speed button. HEADS UP Some AC brands, like certain Daikin or Mitsubishi models, use proprietary communication protocols instead of standard IR. The Breez Plus may only be able to control basic functions on these units. Check Cielo's official compatibility list for your exact model.

Question 3

the screen says 'check filter' but my ac doesn't have a cleanable filter, what's going on?

Accepted Answer

DIAGNOSIS The 'Check Filter' alert is a timer-based reminder you can configure. It is not sensing a dirty filter. The timer has simply reached its set interval. FIX To clear the alert, use the physical controller. Press the 'Menu' button. Navigate using the up/down arrows to the 'Filter Reset' option (icon of a fan with a leaf). Press the 'Menu' button to select it. Press the up arrow to confirm 'Reset'. The alert will disappear from the screen. IF THAT DIDN'T WORK If the alert returns immediately or the menu option is unresponsive, reset the filter timer via the app. Open the Cielo Home app, select your device, go to Settings > Filter Alert. Tap 'Reset Filter Timer'. You can also disable the alert entirely here by toggling it off. HEADS UP The default filter alert interval is 90 days. You can customize this in the app from 30 to 180 days. This setting is independent of your actual AC maintenance schedule.

Question 4

trying to set it up but the app can't find my device during bluetooth pairing

Accepted Answer

DIAGNOSIS The initial Bluetooth Low Energy (BLE) pairing process has failed. This is required before connecting to Wi-Fi. FIX Follow this checklist. 1. Ensure the Breez Plus is in pairing mode: the screen should show a Bluetooth icon and a rotating animation. If not, press and hold the 'Menu' button for 7 seconds. 2. On your phone, disable Wi-Fi temporarily. Active Wi-Fi scanning can interfere with BLE discovery. 3. Enable Location Services/GPS for the Cielo Home app. Android and iOS require this for BLE. 4. Move your phone within 3 feet of the Breez Plus. 5. Force close and reopen the Cielo Home app. 6. Use the 'Add Device' scan function again. IF THAT DIDN'T WORK Perform a factory reset on the Breez Plus. With the device powered on, press and hold the 'Menu' and 'Power' (fan icon) buttons simultaneously for 10 seconds. The screen will go blank and reboot. This clears all settings. Retry the setup process from the beginning. HEADS UP You cannot complete setup on a tablet or a phone that uses a mobile hotspot from itself. Use a standard phone with a cellular connection and a separate Wi-Fi network.

Question 5

unit is making a loud continuous beeping sound, can't make it stop

Accepted Answer

DIAGNOSIS A continuous beep indicates a hardware or sensor fault. The most common cause is the built-in temperature/humidity sensor failing or providing an invalid reading. FIX Immediately disconnect the Breez Plus from the wall outlet. Wait 30 seconds. Plug it back in. The beeping should stop after the boot sequence. Once powered, check the displayed room temperature and humidity on the screen. If it shows '--' or an implausible value (e.g., 0°F or 99% RH), the sensor is faulty. IF THAT DIDN'T WORK If the beeping resumes after the reboot, a critical internal component has failed. This requires manufacturer support. Contact Cielo with your device's serial number (found on the back label and in the app's Device Info screen). HEADS UP Do not cover the vents on the top or sides of the Breez Plus. Blocking airflow can cause the internal sensor to overheat and malfunction, potentially triggering this alarm.

Question 6

the scheduled turn on isn't working, my ac just stays off when it's supposed to start

Accepted Answer

DIAGNOSIS The schedule fails if the Breez Plus loses connectivity or if the AC's physical remote is used to turn the unit off. FIX First, confirm the schedule is active. In the Cielo Home app, go to Schedules. The specific schedule must have the toggle enabled (green). Second, verify the controller is online. The Wi-Fi icon on the device screen must be solid, not flashing. Third, ensure the AC was last turned off using the Breez Plus or its app. Using the AC's original remote or power button breaks the controller's state tracking. IF THAT DIDN'T WORK Check for firmware conflicts. In the app, go to Device Info > Firmware Version. Compare it to the latest version listed on Cielo's support site. An outdated firmware version can cause scheduling bugs. Update if necessary. HEADS UP The 'Away' mode and 'Comfort Settings' (like Early Start) can override or interfere with a basic schedule. Disable these advanced features temporarily to isolate the problem.

Question 7

breez plus keeps disconnecting from wifi, have to reboot it constantly to get it back online

Accepted Answer

DIAGNOSIS This is typically a Wi-Fi signal strength or router compatibility issue. The Breez Plus requires a stable 2.4 GHz network connection. FIX Check the signal strength in the Cielo Home app. Navigate to Device Info. The RSSI value should be better than -70 dBm. If weaker, relocate your router or use a Wi-Fi extender. Ensure the router's 2.4 GHz and 5 GHz networks have distinct SSIDs. The Breez Plus will fail to connect if they are merged under a single name. Reboot your router. Then, on the Breez Plus, perform a hard reset of Wi-Fi: hold the 'Wi-Fi' and 'Menu' buttons for 5 seconds until the Wi-Fi icon flashes. Re-pair in the app. IF THAT DIDN'T WORK Certain router security protocols can cause drops. In your router settings, set the 2.4 GHz band to use WPA2-PSK (AES) encryption. Disable 'AP Isolation' or 'Client Isolation' features for that band. HEADS UP The Breez Plus does not support WPA3. If your router is set to WPA2/WPA3 mixed mode, force it to WPA2 only for the 2.4 GHz network.

Question 8

my cielo breez plus just shows a red exclamation mark on the screen and won't control my ac, what does that mean?

Accepted Answer

DIAGNOSIS The red exclamation mark is the 'No Signal to AC' error. The controller cannot communicate with your air conditioner's indoor unit. FIX First, verify the IR blaster is correctly positioned. It must be directly aimed at the AC's IR receiver, typically behind the front panel's right-side plastic. Distance must be under 10 feet with a clear line of sight. Second, ensure the controller is powered. The wall outlet must be live. Third, confirm the AC unit itself has power and is not in a fault state. IF THAT DIDN'T WORK The IR code library may be incorrect. Use the Cielo Home app. Navigate to Settings > AC Settings > Change AC. Manually select your AC's brand and model. Perform a 'Test' on the Power button. If the AC does not respond, try selecting a different model from the same brand. HEADS UP During the 'Change AC' process, the app will prompt you to point the Breez Plus at the AC to 'learn' codes. This step is critical. Ensure the room is quiet and you are within 3 feet of the AC unit.
