Just an informative post guy's to help anybody out.

Mitsubishi have recently released a WiFi heat pump controller. Their new heat pumps have them built in but you can retro fit the wireless adapter to SOME existing models. I just fitted one to my heat pump on Monday. These allow you to FULLY control your heat pump from anywhere via an Android or iOS app. You can set all sorts of rules from the app i.e. if room drops below x temp then switch on heat pump. I am thoroughly impressed and would recommend these to anybody. I turned the heat pump on 1 hour before I came home today and returned to a warm house. Commands can take up to a minute to happen as they go to Mitsubishi's servers first, it's not a remote control replacement.

Most of the details are on Mitsubishi's site. I have done a bit of an FAQ below incase anybody needs more info. Sorry I didn't take pics of the install but I found a good guide online and I'll post the link.

How much are they?
RRP is $399 - I got mine a lot cheaper due to mitsubishi making an error with the price they quoted me, to their credit they rang me and honoured the price.

Where can I get one?
Apparently they are flying of the shelfs and stock is limited. Mitsubishi sent mine to Smiths City who are selling them.

How much does install cost?
I was quoted between $130 and $200 for a professional installation.

Can I install it myself?
Yes.I did. Mitsubishi say no and recommend a professional installer and include an extremely vague install guide with the adapter but as I say I fitted my own. You'll need to be able to open your heat pump right up and access the control board. Mine took a good while but that was largely due to the location of my heat pump and not having much room to work. The install guide I followed is here http://cleanenergywonk.com/tag/heat-pump/

I hope this helps anybody out who is thinking of installing one. If anybody has any questions I can help with just fire away..........cheers.

I have one, however I am still waiting for an electrician, so my heatpump is just taking up wall space at this stage.

As for installing it, mine came with an installation guide, and but implies you cannot do it yourself. The guide with the heatpump was more detailed IMO than the one with the wifi controller.
In fact in Japan Mitsubishi supply install it yourself heatpumps.

Just to add do what you already have, WPS is required for those who are not aware, and your heatpump does not need to be a designer series. Secondly, if you decide you screw your wifi controller to the wall the you will not be able to see the 3 led indicators that show what fault might be occurring. Rather stupid design flaw.

EDIT:I have not played with the wifi controller yet, but it appears it could beneficial for those who do not have a 7 day remote, or cannot figure out how to use it.

Yes the guide with the adapter was very vague indeed. I rang 5 or 6 installers for quotes and 4 of those had no idea what I was talking about.

VERY good point I forgot to mention you MUST have a WPS router. I Have the fritzbox 7390, it doesn't have a dedicated WPS button but does have WPS in the settings.

I also forgot to mention the obvious! Isolate the power before starting.

Sounds good - is there any public API or REST interface that you can access that you know of? For example if you wanted to integrate into another home automation system.

I have a Daikin heat pump in my place and I was struggling for ages to integrate it with my HA system. However after a lot of research I discovered Daikin have an 'Online Controller' (http://www.daikinme.com/products/index.jsp?singleprv=KKRP01A) which I was able to source from a firm in Australia. This has the option of 'connect to cloud' or 'local IP', which suits me much better (would rather keep everything local if possible).

It wasn't cheap, like your WIFI adapter, and cost me around $340 from memory. I was able to install it myself but it was pretty tricky to get access to the main controller board. It is wired IP only, but you can buy a cheap WIFI-AP adapter if you want WIFI.

I must admit it is pretty cool to have it all hooked up and automated. My 'bedtime' scene ensures it is turned off at night, and I have different set points configured for myself and my wife (she likes it warmer) so if she is home the heatpump is automatically turned up a few degrees.

Probably overkill, $340 to give me that ability, but hey, what price can you put on such geeky toys!

I looked at this but I dont have WPS and will not deploy another network just for it, and I dont see why it cant be ethernet instead.

Also the need to put one per heatpump is a killer. The plan here is for 4 upstairs, so another 1200 to just be able to turn them on and off etc is too much.

Also I did a contact us on their site on the 20th about this, and have not heard back so clearly they dont want to sell me any heatpumps. Really, 10 days and nothing but the autoresponse from submitting the form - screw them in that case.

As far as I know no there is no public API at the moment, I'm hoping they do put one out though and IFTTT get on board. You could have location based rules, If I'm leaving work and the temp is below x then turn on heat pump!

Strange, they were back to me within 24hrs. They came back with completely the wrong price and in the end honoured that price. Couldn't have been happier with their service.

Any sign a Fujitsu Nocria can be made to do this? Sounds handy. I'd settle for a multi day timer, which they couldn't give me when I bought it a couple of years ago.

Two projects to keep an eye on that do this for any heat pump with a IR remote:
indiegogo sensibo (3 days to go)
and
kickstarter tado (finished with RRP of ~US$150, Also they already make a Nest like controller that hard wires into a central heating system)

Both of those products look pretty interesting. The automation would probably suit a bunch of people, but I prefer something in between - something that lets you control heating with an app, according to a schedule, rather than location sensing and such. Is there a cheaper, simple version of those products?

Edit - Peeble Air, US$250 (think it's US). I'll check with Fujitsu NZ about local pricing.

Got an answer today, wonder if its do to with the thread here.

In anycase, no wired option and as I am about to deploy another few unifi's and kill off the junk AP's I have I will have no WPS so cant even use these if I was wanting to put them on wifi.

Am sorting out my sisters place for heating before I will be moving onto my place so hopefully one of the proper band aircons have a ethernet based control system out by the time I do my place.

Richms - Daikin have an Ethernet controller module, see my message above. Works well and is an open API which doesn't require any cloud connection.

Does that work with their ducted range?

Not sure, it is a pretty generic device I think. Check the website I linked above as I think there is a list of supported devices.

A bit of MITM on the uplink to mitsubishi's server would be a nice start to reverse engineering this. You would need to figure out what the pin-out is on that CN105 header and hook it up to some sort of programmable device. Might need something to monitor the signals too.

Unfortunately beyond my expertise, but a dedicated hardware hacker would probably find this fairly trivial!

Mitsubishi now sell the wifi controllers at a cheaper price with a new heat pump as a package deal. They cost more if you want to add later. The little wifi module can be mounted inside or outside the unit but best placed on top. Also the heat pump must be in range of the wps router. They work on the Classic and Designer series heat pumps.
