Smart weekly schedule 
Always come home to a comfortably warm house thanks to the handy weekly schedule. With the app you can easily raise or lower the temperature per room. You can also apply these settings for several days at once. Are you going away temporarily? Then set the thermostat knob to ‘away’ mode to keep the temperature down and ignore all schedules 

Ideal for district or block heating 
Does your home or office use district or block heating? With these smart radiator knobs you can easily set the temperature without having to manually open and close the knobs. The smart radiator knobs are also handy in combination with your own central heating with the (smart) thermostat so you can adjust the temperature per room.  

Open window detection 
The radiator knob automatically detects if the temperature suddenly drops rapidly due to an open window or door, and will then temporarily stop heating so as to avoid wasting energy. You can activate this function for free in the app, and thereby automatically save money on your heating costs. 

Insight into your consumption 
In the app, you can see the set and actual temperature in your home in a clear graph. This graph also shows how many minutes the heating has been on per hour. This allows you to know exactly when you are heating unnecessarily and how much you could save by turning down the temperature. You can also see per day, week, and month how often the heating has been on in total, giving you direct insight into the total consumption of your heating.  

Long battery life 
Thanks to Bluetooth Low Energy technology, the two included AA batteries last up to one and a half years. Because the radiator buttons are connected to the internet via the Hombli Bluetooth Bridge, you can control them anywhere and anytime via the Hombli app.  

Control everything in one handy app 
All Hombli devices can be added in one handy app, allowing them to work together smartly. For example, automatically turn down the heating, turn off Hombli smart lights, and turn on the Hombli Indoor and Outdoor security camera the moment you leave your home using a Geofencing scenario. Alternatively, place contact sensors on a window or door and set the heating to turn off automatically when they are opened.  

Controlling all radiators simultaneously  
Do you have several radiators in a room? Then you can easily link all the smart radiator thermostats together in the app. After linking, the settings will automatically change on all linked radiator thermostats. So, if you increase the temperature on one radiator knob by turning the knob, the temperature will be adjusted on all linked knobs. 

"Hey Google, lower the temperature in the living room" 
This smart radiator thermostat works seamlessly with Amazon Alexa, Google Assistant and Siri Shortcuts for hands-free voice control. Use your voice to turn off the heating when you go to bed early and effortlessly save energy by heating your home for a shorter period. 

Modern and robust design 
The Hombli Smart Radiator Thermostat has a modern and compact design, so it fits into any interior, even if space is tight. The housing has a metal mounting-ring for extra-strong installation. You can control the temperature via the app, or by turning the knob on the radiator thermostat. The clear display shows the temperature after you change it or after you press the button  

Easy installation 
Replace any thermostatic radiator knob in no time with the Hombli Smart Radiator Thermostat. Simply unscrew the fixing of your current thermostat knob and affix the Hombli smart Radiator knob. Additional adapters for Danfoss, Caleffi, Giacomini valves are included which are compatible with most radiator types. Check if your radiator is suitable via: hombli.com/adapter  

Protect radiators against limescale 
If the radiator is left off for a long time, scale and limescale can build up on the inside of the pipes and inside the radiator. This causes the radiator to become less efficient over time. The Smart Radiator has a built-in function to prevent this. It automatically opens the tap for 30 seconds every two weeks. This ensures that during summer that the radiator is still working to ensure optimal usage once winter arrives.

Hair Growth Game Changer
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1), Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
Game-Changer for Hair Growth & Thickness I am seriously impressed with this 100% raw organic Batana oil. I’ve tried so many hair growth products, and this is one of the few that actually delivers real results. Within just a couple of weeks, I noticed my hair feeling softer, stronger, and way more hydrated. The biggest difference for me has been in thickness—my hair looks fuller, and I’m seeing new growth, especially around my hairline. It also adds a really healthy shine without making my hair feel greasy or weighed down. I love that it’s all-natural and unprocessed—you can tell it’s the real deal. A little goes a long way, so the jar will last you a while. I use it a few times a week as a scalp treatment and even on my ends to prevent dryness. If you’re struggling with thinning, breakage, or just want healthier, longer hair, I highly recommend giving this a try. Definitely a staple in my routine now!

This product is helping my afro hair truly thrive!
Scent: Bright Coffee, Size: 2 Fl Oz (Pack of 1)
I've used this product for 1 month so far. Applying to my scalp, hair and the ends of hair approx 1-2 times per week. These are my benefits on my long afro hair: - First off, my scalp doesn't particularly like oil on it, it would trigger itching, dandruff, etc., but it certainly loves this stuff. - bald spots started growing back in. - drastic reduction in hair shed. - For a long while, I had difficulty retaining hair moisture. My hair is FINALLY getting the nourishment and moisture it needs and deserves. - hair is noticeably softer and even more manageable. - I detangled my entire head within 15 minutes the other day which is a first for me. - Hair is thickening. Which in my opinion is because my hair is shedding less. Like my braids appear half an inch thicker than they were. - Scalp stopped itching. - Dandruff stopped. As far as the scent goes, it smells soo good to me. i read authentic batana oil is supposed to smell like burnt coffee. Maybe it's just me but it smells like caramelized honey. All in all I'm soo happy i was guided to batana oil because it has done wonders for me in such a short period of time. Very happy with my purchase and would recommend.

Thicker & Healthier Hair
Scent: Bright Coffee, Size: 4.06 Fl Oz (Pack of 1)
I’ve been using this Batana oil for a few weeks and I can already see a difference in my hair. My hair feels softer, thicker, and looks much healthier. The scalp oil keeps my scalp moisturized without feeling too greasy, and the natural formula gives me confidence that I’m using a quality product. I also noticed less hair shedding and better shine after regular use. The scent is natural and the mask is easy to apply. Great for both men and women who want stronger, fuller-looking hair.
