I've been working with their support for almost a year. They keep assuring me this is fixed, they apply an update, and then I have to prove to them it still doesn't work.I have my Airzone device set so that the Ecobee is the master. But if the Airzone device loses network connectivity, it pushes state to the Ecobee setting it to off, heat only, or some other mode, when the Ecobee was in auto previously. We lost internet one night, and the resident of the room woke up to the Ecobee in off mode and no heat.The device can’t even remember consistently that I’ve disabled the LED.I'll update this review if they ever actually fix this.Edit: after last update from their support the ecobee state hasn’t changed arbitrarily yet. I’ll raise this review to 2 stars from 1. I’m unsure if this update is generally available yet. — Jan 2025Edit: nope, again it changed from auto to heat and changed the temperature settings as well after an internet outage. — Jan 2025

UPDATE (11/26/2024):The device has great potential, but shoddy engineering and horrible tech support prevent customer satisfaction and engineering from learning about real-world customer problems so that the product can be improved. Airzone seems to have many products, and I suspect the Aidoo is an underrepresented or orphaned product. I am a very experienced engineer, and I have offered to talk directly to engineering. Nobody has engaged.I have continued to struggle with this device and the poor support. There are too many problems to sum up here, but here are some examples:* Support only ever responds to one question in an email but ignores the rest* Support does not have a case management system or ticketing system. Require you keep all emails in a single thread, where email size explodes due to having to include prior emails* Cannot set heat lower than 63F. Support claims this is a MEL limitation. MEL thermostats do not have this limitation, nor does it make sense. Who cares that heating is only demanded if, for example, the temperature is 55F or less? This is still a temperature far above the capabilities of the unit.* My unit consistently heated until the temperature was 2-3 degrees above the set point. The answer was that the MEL unit "does its own thing." I discovered a setting in the MEL unit that corrects for hot air rising by applying a 4F offset. Combined with the documented algorithm, which has a 0.9F offset in the other direction, it leads to a 3.1F difference. I am convinced this is the explanation. The setting cannot be controlled through the Airzone, and the Airzone does not force it to "off" when using an external thermostat (Ecobee in my case). Only a native Mitsubishi thermostat can be used to change the setting, but that would be a $300+ purchase to change a setting one time. I tried to suggest they should allow this, but they refuse even to consider it (I suspect the support folks are acting as a barrier to engineering here; it's hard to imagine engineering would not care to address this). Today, I switched the setup to use the Mitsubishi Ti2 thermostat interface. Heating promptly stops when the setpoint is reached. If the Mitsubishi product can do this (because, as documented, they force that setting to off), why can't Aidoo?* Unit forces setpoint on the Ecobee whenever the Airzone temporarily loses connectivity (which happens not infrequently). Their default is: mode off. So it switches the Ecobee to off... leaves the house unheated or uncooled after a temporary loss of connectivity* After I hooked up the Ti2 and disconnected and powered off the Aidoo, their cloud servers were still acting on my Ecobee. I have the nighttime setback to 61F. That is below the minimum of 63F mentioned above. My Ecobee was forced back to 63F until I finally deleted my "site" in the Airzone Cloud. Note that this was happening despite the local device being powered off. Ecobee smarts tried to ramp the temperature down from 65F, where it was before, gradually to 61F. As soon as it reached 62.3F as a setpoint, it was forced back to 63F.* The 63F limitation, combined with the 2-3 degree increased heating problem, does, effectively, not allow an actual temperature below 65-66F: not at night when we want it 61F, and not when we leave for a trip and 55F would be good enough (only option would be to switch the system off, but that would allow temps to drop even lower). Support does not react to this real-world problem. Their only suggestion was to return the product, which I will likely do, although it is beyond the Amazon window, so special arrangements with Airzone will need to be made.ORIGINAL:I bought the Mitsubishi Electric-specific version of the Aidoo Pro. The installation instructions are seriously lacking, suggesting you must also have a MEL thermostat. I have an Ecobee. I contacted NA support and was told no MEL thermostat was needed. I got things hooked up, and the basics seem to be working, but...Also, it is not very well explained: Wires from Ecobee to Aidoo are only ever used if the Internet is down. I.e., Aidoo does not "know" when Ecobee demands cooling or heating. It uses a cloud connection to obtain the temperature setpoint and current temperature and then communicates those to the MEL unit. In that sense, the Aidoo appears like a "communicating thermostat," which is what you want for efficiency reasons.However, Aidoo does not seem to recognize when Ecobee wants to run the fan and does not switch it on or go into Airzone "ventilation" mode. I have only been able to accomplish that through the Airzone app, which kind of defeats the purpose. They should be able to see through the cloud that Ecobee wants the fan to run and do it.Finally, the MEL unit always kicks on when the current temperature is rising but still 2F below the setpoint. It then keeps the temperature there. In other words, it is always 2F cooler than what you set on the Ecobee. This is very counter-intuitive and unwanted.I have tried to get questions answered by NA support, but while they communicate sometimes, they don't answer my questions at all. Secondly, while investigating the 2F difference, they emailed me that they had changed my configuration (without asking me first). This was an incorrect configuration that was cooling the *%@%@! out of my house. Luckily, I came home not long after to prevent a ridiculous bill. This kind of stuff is unacceptable.I have not yet given up on the unit, and I need to escalate tech support, perhaps to Brazil, where I believe the company is located. We'll see.

Bought three Aidoos for my Mitsubishi H2i mini-split heads. I had been fighting with Mitsu's insanely-flawed-and-exquisitely-expensive Kumo Cloud modules for two years, finally ditched them in desperation.Installation was easy once I found the proper path to route cables into the heads' lower housings. Units latched to my wi-fi with zero problems and, totally unlike the Mitsu modules, STAYED latched. App interface is intuitive and clean. BUT BUT BUT:1) The app WILL NOT allow for A/C settings below 67F. Their interface won't even display a head's setting below 67, even if you set it below 67 from the Mitsu remote. This is simply intrusive and draconian; I get all my electricity from my own solar plant and I should be allowed to use it as I see fit.2) AirZone has CONSTANT problems in their back-shop. That is, although the modules are rock-solid within my network, AirZone has recurring and serious issues with the app and its comms to the units. And it's not just me; I have spoken with AirZone reps multiple times wherein they grudgingly and reluctantly eventually admit that their servers are 'down'; 'being maintained'; 'being updated'; and other such platitudes that essentially mean 'we don't know what the hell is wrong and we are struggling'.So it appears to me that, while the individual modules are healthy and robust, nevertheless AirZone's capabilities and the deployed tech to monitor and control their products is either a) not mature, or b) fundamentally unsound/defective.CONCLUSION:Buyer beware.

Do not under any circumstances allow anyone to install this in your home. The company provides zero customer support. They have an email address that is responded by a person who just takes you in circles. READ THE first review, its is exactly what happened to me. When the unit was installed their registration server went down for 5 days over the end of year holiday. If you sell a product that requires online registration to work why would you not have someone monitoring. The minute you plug this in, you have no way of controlling your unit. They do not tell you, that you will need a separate piece of equipment to connect your other thermostat to this unit and the Wifi! This unit will disconnect your existing thermostat without the second splitter. I was stuck for 5 days with no way to control my heat. Why would you not make the app bluetooth or controllable without registration. This is insanely bad piece of equipment. I tried return it and was told no by my HVAC dealer as it is "registered to my name" absolute insanity. ONLY buy the Mitsubishi Kumo contoller if its not available wait for it. You will regret buying this piece of garbage. Go with the Kumo Cloud.
