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)

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.

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.

It does the job BUT.....

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.

Connection issues and lack of analysis

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.

Fine when it works

The app is pretty easy to use most of the time. But whenever the Smartstat device experiences a network interruption it goes offline until I can power it off and on. This is annoying enough when I’m in the house, but a real problem when I’m away as the app becomes useless. I have two devices which both behave the same way, so it appears to be a design fault.
