FEATURES

Otrema Smart Valve bristles with features that presents a viable solution to modern day home heating needs. It took us years of hard work and extensive market research to come up with the best and smartest radiator valve of all time. Its features set it apart from the traditional and manual, or even newly launched thermostatic radiator valves.

Based on Bluetooth 4.0

Developed and designed to be a comprehensive product. It runs efficiently on its own without requiring any extra box such as complex gateway or relay

Room based heating

Set room based schedule to ensure that only appropriate rooms heat up. Select mode such as AWAY, ECO, COMFORT and HOLIDAY for quick access to specific configuration.

Presence detection

OTREMA detects the presence of your phone within seconds to control your heating. It saves heating when you are away and return to normal heating when you are back.

USB recharge

Recharge via micro-USB cable. No need for replaceable batteries hence more ecological and good for our planet too. One recharge can last up to one year.

Reporting

Check extensive temperature and humidity reports based on room and period. In turn, make informed decisions regarding your heating habits.

Optimum heating

OTREMA incorporates inputs such as weather forecast and building characteristics to optimally heat your house.

Open window detection

To further save on your heating bill, we detect when the window is open and reduce heating accordingly.

Extended range

OTREMA valves have been designed to maximize the range. On top the valves act as relay to cascade information to other valves in the house, so range is further increased significantly.

Security

Uses Bluetooth Low Energy technology to connect and communicate with paired devices and smartphones. Only paired smartphone within range can get access to the radiator. No internet, no hacker risks.

Device Firmware Update

As we continiously enhance the product, we will upload these improvements and new functionalities to your Otrema valves free of charge.

FAQ

Got questions? We've got answers. If you have some other questions, feel free to send us an email to contact@otrema.eu

How easy is to install Otrema Valve ? Do I need to hire a installer ?

We would not claim our product to be smart if it was complicated to fit and install. There is no need to hire expensive installer. Just few clicks and you are ready to go.

I have already a thermostat in my home, can I use this valve with my current thermostat ?

Yes, OTREMA valve can work with existing thermostat. If the valves are located in the same room with the thermostat, it is suggested to set the temperature on the thermostat at a higher temperature to ensure control of the room by the valves.

Is OTREMA Valve compatible with my radiator ?

OTREMA smart valve is compatible with most of radiators on the market, either directly or using one of the adaptors included in the package. If you have any doubts, please contact us and we will be happy to assist you.

Can the OTREMA smart valve work without a smartphone ?

Yes, you can still control your OTREMA smart valve even without a smartphone - as you would for standard radiator valve - however the range of functionalities will be limited.

Can I use OTREMA valve with more than one user

Yes, our mobile application allows to manage several users in the same topology home. For example, each member of the family can control its heating system as long as that user has been granted access.

What about the range ?

Up to 100dB path loss is allowed between the phone and the valve to communicate. This is enough on most dwellings, however to maximize range we implemented a proprietary mesh protocol allowing each valve to act a relay to cascade the information. Based on local test on a 2 floor house full point to point coverage is attained. However this depends on the construction material type as well.
