It learns by itself
Your home, your data
Many smart thermostats send everything to the maker's cloud, and some features cost a monthly fee. Not Emthera. It runs on a small box next to your boiler and keeps controlling your heating when the internet is down.
No account to create, no maker's app that can be switched off, no monthly costs.
Everything Emthera does
Everything in this list works today.
Comfort in every room
- A week program for every room
- The living room warm at seven, the bedroom cool at night. Drag a time to change it, copy a day to another.
- Warm right on time
- It learns how fast each room warms up and starts by itself. You choose when it should be warm, not when the heating should start.
- Counts free heat
- Sun through the windows, cooking and people warm a room too. It learns that per room and does not start too early.
- A little warmer, now
- One tap for an hour of extra warmth. A change of your own ends by itself at a time you choose.
- Heat along
- A hallway or landing gets warm when the heating runs anyway, without starting the boiler for it.
- Floor heating and radiators together
- It knows which rooms ask for heat and sets the water temperature to match.
Saves gas
- Water no warmer than needed
- It learns how warm the water must be at each outdoor temperature in your house, and keeps it as low as it can. Cooler water makes your boiler burn more efficiently.
- Lower when you are out
- When everyone has left, the temperature goes down, also per room. When you come home, it gets warm again.
- Holiday planner
- Plan up to eight holidays ahead. The house stays cool and is warm again when you are back.
- Summer mode
- The heating stays off; hot water and frost protection stay on.
- Window open, heating paused
- When a window or door is open, that room pauses until it is closed again.
- Boiler care
- Fewer starts and stops. It tunes the rest between burner starts and the run time itself, by at most one small step a day.
Insight
- Gas use, split up
- For heating, for hot water from the tap and for keeping hot water warm, each separately. Accurate to the cubic metre with a smart gas meter.
- Yesterday against usual
- See whether you used more or less gas than on a usual day, taking into account how cold it was.
- Your boiler in plain words
- Water temperature, water pressure, how often the burner started, hot water, and fault codes explained instead of just a code. It also recognises your boiler model.
- What it has learned
- Per room in plain sentences: how fast it warms up and cools down, and what it changed by itself.
- A clear dashboard
- On your phone, tablet and computer, light and dark, ready-made.
Peace of mind
- Notifications on your phone
- When a room or the house needs your attention. You choose who gets which messages.
- Only real warnings
- A message when something keeps going wrong: water pressure too low or too high, a room that does not get warm, a thermometer that stops reporting.
- Frost protection
- Always on, also on holiday and in summer mode.
- A spare thermometer
- If a thermometer fails, a second one in the same room takes over.
- Works without internet
- The box next to the boiler does it all by itself. If your internet or smart home system is down, it keeps heating on your week program.
A calm switch-over
- Watching first
- If your old thermostat is still connected, Emthera first only watches and shows what it would do differently.
- You decide
- After a short boiler test it takes over only when you confirm.
- A backup every day
- Of all your settings. If the box ever breaks, you put everything back on a new one.
Works with what you have
- Your own thermometers
- Any smart thermometer or thermostat in your home, or wireless thermometers the box receives itself.
- Smart radiator valves
- Per room, and valves on the floor heating manifold too.
- Window and door contacts, and who is home
- For the pauses and the home and away modes.
- The floor heating pump
- It switches the pump with a smart plug, and turns it off when the water to the floor gets too hot.
- Most central heating boilers
- From Nefit, Buderus, Bosch, Junkers and Worcester. Does it fit your boiler?
- English and Dutch
- On the dashboard and on the box.
How do you get it?
Today Emthera runs on a box you buy separately, next to your boiler, together with a smart home system in your own home. What you need and how to start is on What you need.
A box of its own, the Emthera Hub, is in development.
