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.

Good for night sessions
Size: Medium, Pattern Name: Pack of 1
Picked this up for evening fetch sessions and it’s been a win. It charges up fast, couple minutes under a lamp or in sunlight and it’s good to go, and the glow is genuinely bright, not the sad dim purple some of these put out. Makes it way easier to find in the yard at dusk, and the dog can actually track it. It’s a little on the softer side compared to a regular tennis ball, but durable enough to hold up to my big dog, who is not gentle with toys. Still kicking after plenty of chomping and slobber. Fits a standard Chuckit! launcher perfectly, which is the whole point. Pros: • Glows brightly and clearly in the dark • Charges fast from any light source • Holds up well even with a big, enthusiastic chewer • Fits standard ball-throwing sticks • Great for evening or early-morning fetch Cons: • A bit softer than a regular tennis ball — a determined power-chewer could probably destroy it eventually • Glow fades after a while, so you’ll need to recharge it during long sessions • Only glows if it’s been charged, which is obvious but easy to forget Tips: • Charge it under a bright light or in the sun for a few minutes before heading out • A flashlight works in a pinch if you forgot to charge it • Keep it out of permanent fetch duty — rotate with a regular ball so it lasts longer • Not a chew toy, even though it’s tempting to leave it with the dog Five stars. If you’ve got a dog and a yard, this makes evening fetch actually doable.

Best Westie ball ever, my dog loves this ball. Exactly her size! 3" tennis balls are too big & she rips the fur off. this silicone-ish ball has no fur & is 2&1/2 " We have 2" balls from her electronic ball laucher, but she still loves this glow in the dark best!

Best dog ball in the world!
Size: Large, Pattern Name: Pack of 1, Size: Large, Pattern Name: Pack of 1
My dog is singularly obsessed with playing ball. He would drop a steak to chase a ball. (He'd return to the steak, but not without the retrieved ball. He's not an idiot.) He makes dangerous leaps, crashes into trees, and runs fast enough to catch thrown balls before they even hit the ground. Since he doesn't care about his own wellbeing, it's my job to protect him as much as I can. And a lot of balls are hard enough to cause him pain or dental damage when he mistimes a catch. Enter the ChuckIt Glow Ball! The minute Cowboy got his first Glow Ball, he no longer had any interest in the dozens of tennis balls scattered around the house and yard. If I took the Glow Ball away and instead threw a tennis ball, Cowboy would run to retrieve the ball, then return without it and begin looking all over the house for the Glow Ball. The Glow Ball is tough enough to survive Cowboy's big, sharp chompers, yet it's soft enough to do no harm when it hits him in the face. The glow feature is a huge bonus, too. Cowboy gets distracted by chipmunks and squirrels when we're playing, so he sometimes can't remember where he dropped the ball to pursue the interloper. If the ball was exposed to enough light before it was misplaced, it will be easy to find once the sun goes down. (Otherwise, Cowboy always finds it eventually.) When I'm feeling nocturnal, I'll put the ball under a light for a few minutes to activate the electrons, then treat my boy to a middle-of-the-night game of fetch. I was so happy to see these on sale, I bought a lifetime supply for my pantry. The size guide seems accurate. ChuckIt recommended the large size for a dog of Cowboy's weight and that size is perfect. Highly recommended product.

Indestructible Doodle ball!
Size: Large (Pack of 1), Color: Multi
If your dog chews threw every tennis ball and toy, chuckit rubber fetch balls are the only one! Our dog LOVES it, he digs it out and has to have several so that there are a few outside and a couple inside because he chews them when he's bored inside and chases them outside! You dog will love it. It's a great value, especially if you watch for sales. It's our go to fog toy!!
