What kind of “smart stuff” do you want it to do?

 

Wifi so I can operate the heat pump remotely via my iphone.

 

The MHK2 with a Kumo Cloud interface would be perfect. Wireless like what you have. Easy peezy.

 

Thanks, GenesisRefrig. That looks like the best solution. I had a look at the Sensibo Sky controller but I'm not sure if it would work and it has a fairly high (7%) one star rating on Amazon. Moreover, it appears that in app purchases have to be made to obtain full benefit.

 

You will want to double check with your Mitsubishi dealer if the MHK2 is compatible.

 

Why are you changing the temperature so much you need to monitor it?

 

I spend part of the winter in the south of France so I want to be able to monitor and adjust climate conditions in my home here while I'm away so, when it's necessary, I can dehumidify or add heat as needed to avoid condensation or other issues. I do the same with my French home where I've installed SMART hydrometers/thermometers so I can monitor temp and humidity and adjust either by means of SMART plugs fitted to radiators and dehumidifiers. Before we had no dehumidifiers and used to set the stats at around 10oC but would often find the place damp when we returned after being away. The SMART controls have solved that.

 

Just a note here, kumo cloud currently only works on US based cell phones and you won't even find it in the Canadian app store (just throwing that out there since it says you're in BC). If you try to side load it from somewhere else you'll get the notification that it's not available in your region. Since you already have an MHK1 you could try to find an older Honeywell Redlink Gateway and it'll connect to your MHK1 via the Honeywell app. Otherwise you'll have to use a conventional thermostat adapter and the smart thermostat of your choice.
