There is no verified evidence that Xiaomi publishes or guarantees a result of 28.65°C across six rooms. The figure is an unverified claim, not a Xiaomi specification. Xiaomi’s published Mijia models are rated for individual room areas, while a six-room property normally needs multiple indoor units, a properly designed multi-split system, or ducted HVAC.
A Xiaomi Home app can coordinate equipment and display sensor readings, but software control does not create ductwork, airflow, zoning, or cooling capacity. Before relying on the headline figure, verify the exact model, installation, room sizes, sensor method, weather conditions, and room-by-room results.

What the 28.65°C claim actually proves
At present, nothing establishes that “28.65°C across 6 rooms” is an official Xiaomi performance result. The searched Xiaomi material does not identify a matching announcement, test report, product page, or standard benchmark. The number should therefore be treated as an asserted measurement until its source and methodology are available.

A six-room average of 28.65°C could hide a substantial difference between rooms. For example, a cool room and a hot room might produce that average while occupants in one space remain uncomfortable. A credible report would show each room’s reading, not just the mean.

Which Xiaomi air conditioner is being discussed?
“Xiaomi air conditioner” is too broad to support a performance conclusion. A proper assessment needs the product family and model number, cooling capacity, region of sale, voltage, indoor-unit count, outdoor-unit count, refrigerant, installation details, and software version.
Xiaomi’s cited global product pages describe wall-mounted split systems with materially different capacities:
| Model | Published cooling capacity | Published recommended area | What it does not establish |
|---|---|---|---|
| Mijia Air Conditioner Eco 2.6 kW | 2,800 W | 10–20 m2 | Cooling six enclosed rooms |
| Mijia Air Conditioner GentleAir 2.6 kW | 2,800 W | 10–20 m2 | Whole-home temperature uniformity |
| Mijia Air Conditioner GentleAir 5.2 kW | 5.2 kW class | 40–55 m2 | A six-zone design for a particular home |
| Mijia Air Conditioner Eco 7.0 kW | 7.0 kW class | 50–70 m2 | Automatic cooling of six separate rooms |
For the cited 2.6 kW models, Xiaomi lists inverter operation, approximately 600 m3/h circulating-air volume, Xiaomi Home and voice control, and a 220–240 V, 50 Hz supply. These are product specifications for the relevant unit; they are not a six-room certification.

A single split air conditioner is designed to deliver conditioned air into the space where its indoor unit is installed. Closed doors, walls, corridors, different solar exposure, insulation, ceiling heights, occupants, appliances, and windows all limit how much cooling reaches other rooms.
That makes the following distinction essential:
- One unit with a smart app: remote control and monitoring of one appliance.
- Several Xiaomi-compatible units: multiple appliances coordinated through Xiaomi Home.
- A multi-split system: several indoor units connected to one or more outdoor units and designed as a refrigerant system.
- Ducted HVAC: conditioned air distributed through designed ductwork, often with zones and dampers.
Only the latter arrangements are naturally suited to six enclosed rooms. A large 7.0 kW unit may suit a large open area, but its 50–70 m2 guidance does not mean it can deliver equal cooling to six bedrooms behind closed doors.

When a six-room result might be plausible
The claim could be physically plausible in a limited sense if the property is mostly open plan, doors remain open, the rooms are small, the target is only to reduce heat rather than maintain a uniform temperature, or several indoor units are operating together.
It becomes misleading when one small wall-mounted unit is presented as cooling six closed rooms, when some rooms are merely receiving residual airflow, or when the system’s own nearby sensor is treated as a whole-house measurement.
How to verify 28.65°C properly
A defensible test should document all of the following:
- Exact indoor and outdoor unit model numbers.
- Number and position of indoor units.
- Floor area, ceiling height, and layout of each room.
- Initial and final temperature for every room.
- Outdoor temperature and relative humidity.
- Air-conditioner mode, set point, fan speed, and swing settings.
- Whether doors and windows were open or closed.
- Sensor make and model, placement, calibration, and sampling interval.
- Test duration and whether readings were simultaneous.
- Energy consumption, occupancy, and whether the result was repeated on multiple days.
Sensors should be placed at approximately occupant height, away from supply vents, exterior walls, direct sunlight, windows, and heat-producing equipment. The air conditioner’s internal sensor is useful for controlling that unit, but it may not represent a distant room.
The results should look something like this:
| Room | Sensor position | Start | End | Duration | Outdoor conditions |
|---|---|---|---|---|---|
| Room 1 | About 1.1 m high, away from vent | — | — | — | — |
| Room 2 | About 1.1 m high, away from vent | — | — | — | — |
| Rooms 3–6 | Document each separately | — | — | — | — |
Report the minimum, maximum, median, arithmetic mean, and range. The range matters as much as the average. Also record relative humidity: 28.65°C can feel very different in dry and humid conditions, and temperature alone cannot establish comfort.

How Xiaomi’s published claims should be read
Xiaomi advertises features such as rapid cooling, AI energy-saving modes, self-cleaning, app control, and voice control on relevant product pages. Those claims are associated with particular models and, in some cases, stated test conditions. They should not be converted into a household guarantee.
Recommended Free Tools
For example, Xiaomi’s Eco 7.0 kW page cites an AI energy-saving figure of up to 21.9% under stated conditions. That is a manufacturer test claim, not a universal saving for every home. Actual results depend on weather, insulation, set point, occupancy, installation quality, operating schedule, and the existing system used for comparison.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Choosing a six-room design
Room-by-room sizing should account for floor area and ceiling height, window orientation and shading, glazing, insulation, construction, occupants, appliances, lighting, local design temperature, door-opening patterns, pipe or duct lengths, and simultaneous demand. Multiplying a nominal room rating by six is only a rough screening exercise and is not a final HVAC design.
Open-plan home
One appropriately sized Xiaomi unit may be suitable for a genuinely open area if its published area guidance and a heat-load assessment support that choice. Expect temperature gradients near corridors, kitchens, windows, and sun-exposed areas.
Six enclosed rooms
Use multiple independently controlled split units, a properly designed multi-split system, or ducted HVAC. If every room must remain within roughly 1°C of the target, room-level equipment and sensing are more appropriate than relying on air transfer through open doors.

Existing Xiaomi smart home
Xiaomi Home may be useful for schedules, remote operation, temperature monitoring, and automations. Add sensors only to measure and coordinate the system; they cannot compensate for undersized equipment or inadequate distribution.
United States and other non-220–240 V markets
The cited 2.6 kW global specifications list 220–240 V, 50 Hz. Do not assume that a model listed on Xiaomi Global is sold, certified, serviceable, or warrantied in the United States. Confirm local electrical compatibility, certification, installer support, spare parts, refrigerant requirements, and warranty terms before purchase.
Installation issues that affect the result
A six-room installation can require refrigerant-line routing, condensate drainage, electrical upgrades, outdoor-unit mounting or slab work, wall penetrations, access for maintenance, and professional commissioning. Poor line installation, inadequate drainage, weak airflow, incorrect charging, or poor sensor placement can undermine an otherwise suitable design.
Oversizing is not a complete solution. A unit that is too large may cycle for short periods, remove less humidity, create uneven temperatures, and cost more to install. A licensed HVAC professional should confirm the load and system architecture.

Bottom line
The Xiaomi name and Xiaomi Home integration do not validate the claim of 28.65°C across six rooms. Xiaomi’s published figures describe individual models and recommended areas, not uniform six-room performance. Treat the number as unverified unless the original test provides per-room readings, sensor methodology, duration, weather, humidity, and full installation details.
For six enclosed rooms, choose the system architecture first—multi-split or ducted HVAC in many cases—then confirm capacity, electrical compatibility, local support, and room-by-room commissioning. A smart app can coordinate a correctly designed system; it cannot replace one.
