About this app

With the calor BT app and BLUETOOTH® Smart Radiator Thermostats by eQ-3 you can comfortably control your individual comfort temperature via smartphone. Your defined heating profiles are securely and easily transmitted via BLUETOOTH® Smart to the radiator thermostats. In this way, you will always find your ideal room temperature - without wasting energy while nobody is at home. The BLUETOOTH® Smart Radiator Thermostats can be quickly and easily installed, without having to drain any water or intervene in the heating system. Simply replace your conventional radiator thermostats by BLUETOOTH® Smart Radiator Thermostats and start saving energy!

With the calor BT app, up to five BLUETOOTH® Smart Radiator Thermostats can be configured and controlled right from the beginning.

Easy configuration
In the app, the BLUETOOTH® Smart Radiator Thermostats are easily taught-in and allocated to rooms. The user-friendly display of set-up rooms enables intuitive control via the app.

Individual comfort temperature for each room
You can comfortably control the room temperature via the app e.g. from your sofa and adjust your heating control system to your personal needs.

Individual time control
With freely programmable heating profiles you can define individually tailored temperatures for each room at any time and create heating profiles with up to three heating phases per day. In this way, your home will only be heated when it needs to be. No more heating energy will be wasted while you are not at home and your energy savings will increase considerably.

Automatic mode
The automatic mode can be activated via the calor BT app. The BLUETOOTH® Smart Radiator Thermostats regulate the room temperature according to your defined and selected heating profiles.

Manual mode
Also the manual mode can be set via the app. The automatic mode is stopped and the radiator thermostats will remain at a defined temperature.

Holiday mode
To ensure that no heating energy will be wasted while you are out of the house (e.g. for holidays) you can activate the holiday function via the app before your journey. The temperature is then reduced via the BLUETOOTH® Smart Radiator Thermostats until a previously defined time. Afterwards, the rooms will be set back right in time to your personal comfort temperature so that a warm and cosy home will be waiting for you after your journey.

Boost function
With the boost function, cool rooms can be heated within short. The function can be activated either via the app or directly at the device. The heating valve opens completely for five minutes. There will be a pleasant room temperature right away because of the radiated heat. By the end of the boost phase, the BLUETOOTH® Smart Radiator Thermostats automatically change back to the prior operating mode.

Ratings and reviews

A good app but, needs improvement. I like how I can set the schedules via the app - much easier and quicker to do and, I also like how I can make a change on my phone whilst I'm in bed. There's some important features missing in this app though: - current temperature reading from the TRV - no indicator to show if the TRV is currently heating (open) or not. - there's no option to change the length of the 'boost' button. 5 minutes is not long enough. This needs to be more like 15-20 minutes

Update: Latest update broke everything - all thermostats are gone, Bluetooth permission missing, nothing works. Pairing doesn't last. Old review: It works, mostly, kinda. Pairing is annoying (there is a screen without any action buttons or explanation), and programming is less featured than using the on-device buttons, i.e. you cannot choose to heat until 24:00 or 23:59. But at least it's not styled in some fancy unusable way.

Just got my smart thermostat a d connected it with the app. First it worked totally fine, but after updating the firmware of the thermostat tot 1.46 the screen goes blank (instead of showing PAIR and a pairing code) when holding the dial for 3 sec. Therefore I can't pair it to my phone anymore even though the thermostat does show up when wanting to pair a new Bluetooth device. So.. without Bluetooth the smart radiator thermostat isn't that smart anymore... (Ps. Would love to have it solved)
