Mitsubishi Kumo Cloud Integration
« on: July 20, 2016, 04:04:35 pm »
Hello all,

I've recently had a large Mitsubishi HVAC system installed in my home.  I got the Kumo Cloud wifi based control system with the equipment so I can use the app to control each unit.  That's great but I would prefer to integrate it with Vera so I can write scenes to trigger different events. 
After doing some research it seems like Kumo Cloud is either new technology or no one else has it.  There's very little on the internet regarding the Kumo Cloud interface.  I have to imagine there must be a way to integrate this with VERA but I can't find anything.  Do any of you know if this would be possible?

Thanks for introducing this new product. I too have many Mitsu ductless systems and I wasn't aware of this - until now. Seems Mitsu developed this in addition to Honeywell's TCC (which is what I'm using today) and to offer wireless as seen by other ductless manufacturers (e.g. Daikin). This appears to give more granular control over functions lacking within TCC (e.g. Dry mode, airflow direction etc.). So yes, something can be developed but it's critical to have a published API. Of course one could always monitor the traffic and reverse engineer one.

So without home automation, what are your initial thoughts on the controls offered by Kumo ? Any inherit delays or deficiencies in issued commands ?

It appears to be a solid platform and beats the heck out of using the IR remotes that for some reason still come with these top of the line HVAC units.  On a sidenote, that kills me...awesome product, inverter driven compressors, silent operation, highly efficient heat pump and they ship with a IR remote.  Not wifi, not even RF...IR, freakin IR!  Anyway...

The only gripe I have is the initial startup lag when you launch the app and it needs to contact each individual unit.  At times it takes less than a couple seconds for each unit to report back its current status but other times it can take up to 2 minutes.  This happens on the home wifi or miles away on 4g cell service.  Once its "connected" any command is executed instantly and consistently with positive feedback showing in the app itself which is great.  As long as you leave the app running in the background it doesn't need to reconnect and appears to update regularly.  If you completely close down the app you may need to wait for it to reconnect to each unit. 

I'm not sure if the number of units affect the startup time.  In the beginning I had one setup and it was fast.  I now have 4 of the wifi modules on a 6 ton system and she's a bit of a slow mover. 

I hope someone much smarter than myself is able to put together an interface.  It seems all the pieces are there we just need someone to connect the dots.

Ah, yes the dreaded remotes. Don't get me started on those... I'm definitely curious a this point, I might purchase one and install it just to see how it works. I appreciate you taking the time to provide details...

So I did some searching and it seems for whatever reason (perhaps simplicity), a WAP that supports WPS is a requirement. Next spring (way too hot in Texas to do this now) I'm going to install a tri-system on the east side of our house and was looking to adopt this solution. It's advisable that once you've successfully paired the units to the AP, proceed to disable the WPS feature. I use a commercial grade router and these simply don't support WPS. Do a search and you'll see why WPS is becoming an issue.

I simply can't stand residential routers, so I'm going to use an rPi2 with a WiFi dongle and OpenWRT and isolate it onto it's own VLAN. If someone hasn't PCAP'd the traffic by then ,I will so we can start to see we can explore the details necessary to start building a plugin. I can then successfully retire my Nest thermostat and the Honeywell's (and RedLink bridge) which control my 3 Mitsu's today. Mikee has done an awesome job building that plugin and it's been rock solid...

In the meantime I'll keep checking Git for anyone who's hacked Kumo.. This is good news though...

Code: [Select]
If service from my Internet Service Provider goes out can I still
use the app? Yes! As long as the local network is functioning the
app can communicate to the HVAC units. You may have to disable
the data connection on your mobile device to use only the WI-Fi
network, temporarily, until Internet is restored. Choose to use the
wireless network As-is or choose Use Without Internet
from the alert in iOS

Well that's encouraging news for sure! 

I've been using the schedule feature in Kumo for the past few days and have also found that to very reliable.  I have an MHK1 on my ducted minisplit (Kumo Cloud adapters on the 3 wall mount units) and have found the Kumo cloud to be a MUCH BETTER and less expensive option than the MHK.

Yes, the MHK1 solution is 50-60+ for each unit. Not having to swap batteries on the MHK1 and look at these antique looking stats will be worth it to me. I went ahead and ordered the parts for my OpenWRT/WPS access point, 65+ for parts and I can access it remotely if needed using Weaved. I'll probably order the Kumo adapter when I can free up some time and the temps start to cool down. I've been hunting Ebay to see if anyone decides they don't want it.

One of the things I dislike about cloud based solutions is having to converse with them directly to send commands to the HVAC's. Direct communication will be nice !

as of October 2016 this is no longer the case. The newer Wi-Fi adapter do NOT require WPS.
Wi-Fi Adapter (PAC-WHS01WF-E) older model, Requires WPS
Wi-Fi Adapter (PAC-USWHS002-WF-1) Newer Model, does NOT require WPS

Now we need someone smart enough to crack the communications so we can integrate into home automation.
there is a thread here where by someone has started investigating the coms. Its encouraging to me at least to see it appears to be json strings as my automation system works off those heavily.

In case any of you are interested. I coded a KUMO like controller with an ESP8266. Does same thing, except you can decide what controls it, not Mitsu LOL...I will be making demo samples soon with MQTT, for now there are demo's in the git so that anyone can make their own thing using my library.

We recently discovered how to use remote temperature sensors and send that to the HeatPump, so that it uses that temperature instead of it's own to determine if it should cool/heat or not and at what stage. This is good for ducted units in an attic, where temperatures reported by the heatpump are not the room temperature. MHK1 accessory from Mitsu does this, but is not remote WIFI enabled. We can now do the same as that accessory, but can change settings from any automation software that can do MQTT.
It is currently in a test branch, but will soon be merged into the master. The MQTT sample script will also be updated to support receiving remote temperatures and feed them to the heat pump.

@Swi,

I've been actively following the progress and it's greatness - so wish I could help test but I've been so swamped at work. I currently have all the parts and I just recently setup the MQTT plugin. I just need to assemble the cable and give it a go. If I have any questions I'll post on Git.
