Quick answer: If you own a Mitsubishi Electric mini-split and you’re tired of kumo cloud, you have two routes. Stay official with Mitsubishi’s Comfort app (the direct replacement for kumo cloud) plus a supported Wi-Fi adapter, or go third-party. The best third-party pick for most homes is Sensibo Air Pro for its polished app, smart-home integrations and air-quality sensing. Cielo Breez Max is the best value with a built-in touchscreen, Flair Puck is the best room-by-room “thermostat” experience, and SwitchBot Hub 2 is the cheapest way to add basic Wi-Fi control. Tinkerers who want fully local control can use Home Assistant with a CN105 serial adapter.
Search for “kumo cloud alternative” and you’ll find a lot of frustrated owners: dropped connections, schedules that didn’t stick, and confusion after Mitsubishi rebranded the app. This guide explains what actually changed, which alternatives work with Mitsubishi mini-splits in American homes, who each option is for, and the questions people ask most before switching.
What Happened to kumo cloud?
Mitsubishi Electric Trane HVAC US replaced kumo cloud with the Comfort app by Mitsubishi Electric. The Comfort app launched in spring 2025, and existing kumo cloud installs on iPhone and Android update to it automatically when app updates are turned on. Mitsubishi says Comfort works with existing Mitsubishi systems and with newer units that have built-in Wi-Fi, adds seasonal scheduling (separate summer and winter schedules), and supports multi-zone homes.
Two practical details matter before you decide anything:
- Adapter compatibility: The current Wi-Fi interfaces (PAC-USWHS002-WF-1 and PAC-USWHS002-WF-2) carry over to the Comfort app. Older interfaces such as the PAC-WHS01WF-E are not supported, so those systems need a newer adapter or a third-party controller.
- 2.4 GHz Wi-Fi only: Like kumo cloud, the Comfort app needs a 2.4 GHz network for setup and operation. If your router merges 2.4 and 5 GHz under one name, setup can fail. Our mesh Wi-Fi guide covers routers that let you split bands or add a dedicated IoT network.
So “kumo cloud alternative” can mean two things: moving to the official Comfort app, or replacing Mitsubishi’s cloud entirely with a third-party controller. We cover both.

Wired vs Infrared: The One Thing to Understand First
Every kumo cloud alternative falls into one of two camps.
Wired (two-way) controllers plug into a connector on the indoor unit’s control board. They see what the unit is really doing: current mode, set point, fan speed and error codes. If someone uses the handheld remote, the app updates. Mitsubishi’s own adapters and the Home Assistant CN105 route work this way.
Infrared (one-way) controllers such as Sensibo, Cielo, Flair and SwitchBot sit in the room and “press the buttons” on your behalf, just like the remote that came with the unit. They’re easy to install and work with almost any brand, but they assume the command was received. If the line of sight is blocked or someone uses the original remote, the app can get out of sync. Good IR controllers reduce this with room sensors and smart logic, and for most bedrooms and living rooms they work well.
Rule of thumb: if you want error codes, contractor access and guaranteed state, go wired. If you want the best app and automations with zero electrical work, go infrared.
The Best kumo cloud Alternatives, Reviewed
1. Mitsubishi Comfort App + PAC-USWHS002-WF-2: Best Official Option
The simplest “alternative” is the official successor. The Comfort app keeps everything kumo cloud did (temperature, fan speed, vane direction, schedules and alerts) and adds seasonal schedules, connection history and contractor linking. Mitsubishi has shipped steady updates since launch, including kumo station management, filter reminders and high/low temperature alerts.
Who it’s for: Owners with a supported adapter who want two-way control, real error notifications and a setup their HVAC contractor understands. If your unit already uses a WF-1 or WF-2 adapter, there’s no hardware to buy.
Watch out for: Early versions drew complaints about logouts and schedules. If you tried Comfort in 2025 and gave up, it’s worth a second look after the later updates. Systems with the old PAC-WHS01WF-E adapter need an upgrade.

2. Sensibo Air Pro: Best Third-Party Overall
Sensibo has been the go-to mini-split controller for years, and the Air Pro is its most complete model. It adds air-quality sensing (particles and VOCs on supported models) on top of temperature and humidity, and its app is the most polished in the category. Geofencing can turn units off when everyone leaves and back on as you head home, and “Climate React” rules can switch modes based on room temperature or humidity.
Who it’s for: People who want the best app, deep automations and integrations with Alexa, Google Assistant and Siri Shortcuts without touching the indoor unit.
Watch out for: Some advanced history and features sit behind the optional Sensibo Plus subscription. The basic controls work without it. If you don’t care about air quality, the cheaper Sensibo Sky or Sensibo Elements covers the essentials.

3. Cielo Breez Max: Best Value With a Touchscreen
Cielo’s Breez line is popular with mini-split owners because the controller itself has a screen, so it doubles as a wall-mountable “thermostat” for people who don’t want to reach for a phone. The Breez Max adds a larger touchscreen and is easy to pair with Mitsubishi remotes. The Cielo app handles schedules, geofencing and comfort modes that hold a target temperature or humidity.
Who it’s for: Households with kids, older relatives or guests who want a physical control on the wall, and anyone who wants strong features at a lower price than Sensibo.
Watch out for: Like all IR controllers, it can’t read true unit status. Some premium features need an optional Cielo subscription.

4. Flair Puck: Best Room-by-Room Control
Flair markets the Puck as a smart thermostat for mini-splits, window ACs and portables, and that’s how it feels. It measures temperature where you actually sit instead of at the indoor unit near the ceiling, which helps mini-splits that overshoot or short-cycle. You set the temperature by rotating the Puck, can lock guests to a temperature range, and revert to defaults when they leave. The first Puck plugs in; extra Pucks can run on batteries.
Who it’s for: Multi-room homes, Airbnb and rental hosts, and anyone who wants a simple dial on the wall with 7-day schedules per room. Flair says the Puck works with more than 200 mini-split brands, including Mitsubishi.
Watch out for: Fewer third-party integrations than Sensibo, and IR limits apply.

5. SwitchBot Hub 2: Best Budget Option
If all you want is to turn the mini-split on before you get home, a universal IR hub is the cheapest fix. The SwitchBot Hub 2 learns or auto-detects your Mitsubishi remote, shows room temperature and humidity on its small display, and can bridge devices into Matter so you can control the AC from Apple Home, Alexa or Google Home. It can also run TVs, fans and other IR gear in the same room.
Who it’s for: Renters and budget buyers who need basic remote control and simple scenes, and people already in the SwitchBot ecosystem. Pair it with the ideas in our smart home hub guide.
Watch out for: Climate automations are more basic than dedicated mini-split controllers.

6. Mitsubishi MHK2 Thermostat + kumo station: Best Wall Thermostat Feel
If your problem with kumo cloud was having to use a phone at all, Mitsubishi’s MHK2 wireless thermostat gives each zone a real wall control that reads the room temperature. Paired with a kumo station (which the Comfort app still supports), you also keep remote control and can tie in outdoor-temperature logic for mixed heat-pump and furnace setups.
Who it’s for: Homeowners who want an official, two-way wall thermostat and are happy to have a contractor help with setup.
Watch out for: It’s the most expensive route per zone and is less DIY-friendly. Check that your indoor units are compatible first.

7. Home Assistant + CN105 Adapter: Best for Local, No-Cloud Control
Many Mitsubishi indoor units have a CN105 connector on the control board, the same port the official Wi-Fi adapter uses. The Home Assistant community has popular open-source ESPHome projects that use a small ESP32 board on that connector to give full two-way control on your local network, with no cloud account at all. Status, set point, fan, vanes and room temperature all show up in Home Assistant, and you can automate with any sensor you own.
Who it’s for: Comfortable DIYers who already run Home Assistant and want reliability that doesn’t depend on any company’s servers.
Watch out for: You’re opening the indoor unit’s cover and connecting to its control board. Turn the power off at the disconnect, understand that it may affect warranty or contractor support, and use a pre-built adapter if you’re not comfortable soldering.
How to Choose the Right kumo cloud Alternative
- Check your adapter first. If you have a PAC-USWHS002-WF-1 or WF-2, the Comfort app is free to try before you buy anything.
- Decide wired vs infrared. Wired gives true status and error codes; infrared is plug-and-play and works with any brand.
- Think about who uses it. Guests and older family members do better with a physical control (Cielo Breez Max, Flair Puck, MHK2).
- Count your zones. One IR controller is needed per indoor unit, so a four-zone home means four devices.
- Check your ecosystem. Want it in Apple Home? Look at Matter bridges (SwitchBot) or Sensibo’s HomeKit options. Alexa and Google are supported by almost everything here.
- Plan for subscriptions. Sensibo and Cielo work without one, but some extras are paid.
- Fix Wi-Fi. Many “kumo cloud is unreliable” complaints are really weak 2.4 GHz coverage near the indoor unit.

FAQ: kumo cloud Alternatives
Is kumo cloud discontinued?
Kumo cloud has been replaced by the Comfort app by Mitsubishi Electric. If automatic app updates are on, your kumo cloud app updates to Comfort on its own, and Mitsubishi says existing compatible adapters keep working.
What is the best alternative to kumo cloud?
For two-way official control, the Comfort app with a supported Mitsubishi adapter. For the best third-party experience, Sensibo Air Pro. For value with a screen, Cielo Breez Max. For local control, Home Assistant with a CN105 adapter.
Does Sensibo work with Mitsubishi mini-splits?
Yes. Sensibo controllers work with most Mitsubishi mini-splits that use an infrared remote. Because they use IR, they can’t read the unit’s real internal status the way a wired adapter can.
Can I use a regular smart thermostat like Nest or ecobee with a Mitsubishi mini-split?
Not directly in most cases. Standard thermostats expect 24V wiring that ductless indoor units don’t have. Mitsubishi sells thermostat interface kits for some systems, but the simpler path is a mini-split controller or Mitsubishi’s own MHK2 thermostat.
Why won’t my Mitsubishi Wi-Fi adapter connect?
The most common reasons are a 5 GHz-only or combined-band network (the adapter needs 2.4 GHz), a weak signal near the indoor unit, or an older PAC-WHS01WF-E adapter that the Comfort app doesn’t support.
Do these controllers work with Alexa and Google Home?
Yes. Every option in this guide can be controlled with Alexa and Google Assistant, either directly or through Home Assistant. Apple Home support varies, so check before buying.
Will a third-party controller void my Mitsubishi warranty?
Infrared controllers don’t touch the unit, so they don’t affect it. Opening the unit to add a CN105 adapter is different; check your warranty terms and ask your installer if you’re unsure.
Bottom Line
If you have a supported adapter, give Mitsubishi’s Comfort app a fair try first since it costs nothing and keeps two-way control. If you want a better app or your adapter isn’t supported, Sensibo Air Pro is the best all-around kumo cloud alternative, Cielo Breez Max is the best value, Flair Puck wins for multi-room and rentals, and SwitchBot Hub 2 is the budget fix. For complete independence from the cloud, Home Assistant with a CN105 adapter is hard to beat.
