## What is Heatmiser SmartStat?

The Heatmiser SmartStat is a WiFi Connected Thermostat that connects directly to your home router.

Easy Setup - No Port Forwarding or Fixed IP Address Required. 

The SmartStat can work as a thermostat or timer - so those looking to control heating and hot water would require 2 SmartStats - one to replace their existing thermostat and the other to replace the programmer.

SmartStat App Offers:
- Geo Location Feature (Multi Zone & Multi Users Supported)
- Multi Zone Control
- Multi Location in One App - (Main Home & Holiday Home)
- Multi Device Control
- Apply Temperature Hold to a single or selection of zones
- Apply PIN Number Lock to a single or selection of zones
- Home / Away Facility 
- Holiday Facility
- Program Heating and Hot Water Times
- View Live Temperature from your Home on your SmartPhone
- Auto Firmware Update
- Internet Clock Sync (Summer/Winter Time Correction) 

SMART STAT APP - COMING OR GOING?
SmartStat App allows you to instantly switch your heating and hot water controls ON or OFF directly on your smartphone or tablet. Not only will this save money, it ensures your home is always warm and welcoming when you arrive.

Better still, the SmartStat will automatically activate your heating if the frost set temperature is reached; keeping your home safe and dry without wasting any unnecessary energy.

SMARTSTAT APP - MULTI ZONE CONTROL
Heatmiser's SmartStatApp allows you to zone your home heating and control each zone independently from the SmartStat App. Imagine having all rooms at an ideal temperature and being able to change settings instantly to suit your immediate needs. Not only will you optimise family comfort; you will optimise energy efficiency as well.

### 1/5 — No update for over 5 years!!

*2022-09-25*

This app hasn’t been updated for over five years so it’s just a matter of time now before it stops working with the latest releases of iOS and then my Thermostat becomes obsolete and unable to control from outside my home….. 😏

### 1/5 — App is frozen

*2021-03-11*

The short story is that I can’t get the app to work. It’s frozen. Pretty reluctant to delete and reinstall since it appears to no longer be supported.

### 1/5 — Is this App still supported?

*2020-04-15*

Constantly offline have to delete and reload App but won’t connect to thermostat now. Notice no App updates for a year! Is this App still supported?

### 5/5 — Does everything I need.

*2019-11-25*

It works as it should, does everything I need it to do. 
It could maybe do with a makeover to freshen it up.

### 3/5 — Old hat

*2019-11-19*

While the app does what it should the design and screen size is years out of date. 

Obviously no more development from the company.

### 2/5 — Unreliable

*2019-07-25*

Frequently is ‘offline’ and inaccessible . Every time holiday mode is used the app needs deleted and re-downloaded as it won’t reset back to normal mode .

### 4/5 — Useful for remote control

*2019-04-24*

I have used this for a few years now. It allows me wide-ranging control of my holiday cottage heating from afar. I used to have problems with it dropping out on occasion which required the housekeeper to hard reset the stat (powering the boiler off) but I now believe that was a router issue - it hasn’t happened since moving to a better modern Wi-fi router. I would also like to see a history option and would like the functionality that has just been added to Neo for the stat to be included in Alexa routines.

### 1/5 — Not really up to the job

*2019-04-01*

Desperately needs an update. Very hit and miss if changes in the app are carried over to the heating system. No heating history. Very clunky app which just not good enough. Developers need to take a look at the Nest app which is superb.

### 3/5 — Connection issues and lack of analysis

*2018-07-10*

I have problems with the stats losing connection every now and again which is frustrating. Can’t they be developed to reconnect if this happens?

Also agree that some history/analysis would be useful.  There are barely any updates which means you will lose out to competition eventually.

### 2/5 — It does the job BUT.....

*2018-04-01*

Could do with a revamp. I have 2 stats in my house., viewing them on my phone is like going to iPhone 4 formatting.. no sophistication about the app. But does the job. App is quite crude. Doesn’t have analytics.. and the Wake Leave Return Sleep is ridiculous, as comfort levels should be infinitely adjustable. And confusing if Stat is located in a bedroom zone.. as you don’t want Heating ON in the bedroom after WAKE up!! Cos your going to the living room/kitchen zone etc.
