Your ultimate wireless auto fill pool, spa, pond and water feature solution

LevelSmart is the only dependable wireless autofill solution on the market today. Applicable to pools, spas, ponds, and water features, it is the only simple retrofit to eliminate the chore of manually filling your body of water. With a small and sleek sensor that can be tucked into the skimmer throat, it goes virtually unnoticed. The install requires no deck destruction, no new lines to transport water and nothing over the deck to trip over.

How LevelSmart works

LevelSmart sensor wakes up every 30 minutes (48 times a day) to check your water level. If it identifies the current water level is below the set level, it will actuate the valve for seven minutes. After seven minutes of fill time, it will shut the valve off as a fail-safe but will check again 30 minutes later. This ensures you will never overfill while keeping your pool level perfect.

How to calculate antenna length

When selecting your antenna cord length, consider the amount of antenna cord you will need to get the antenna tip in a spot where it can successfully communicate with the sensor in the pool. For best results, we recommend to always try to get the antenna tip in a position where it can see the pool (even though this isn’t always required). From the antenna tip to the sensor in the pool, there is a communication distance of 1000 feet in the line of sight.

LevelSmart Autofill: the Only Wireless Pool AutoFill Solution You Can Trust

The LevelSmart wireless auto-fill is the most dependable autofill on the market today. Born from the frustration of the thousands of pool “leaks” that were actually a faulty autofill, we knew we could create a solution that will be reliable and effective.

Your pool, spa, pond or water feature will naturally lose water due to evaporation, along with factors including pool use, splash out, leaks and faulty autofills.

Kona Labs automatic pool fill system is made right here in America to ensure quality and a long life. Water level controllers come in different types, some electronic and some manual, but never has there been a reliable wireless solution until LevelSmart. Whether you are using it for an automatic spa fill system or for your pool automatic pool fill system, you will see the quality and ease of use upon install.  Most automatic fill for pools and spas are made overseas and are extremely unreliable which is why make sure our quality is unmatched.

What can LevelSmart wireless pool autofill do for you?

The first advantage of using an  autofill for spa or pool auto fill lies in eliminating the chore of manually filling your pool or spa.  Therefore, by using an autofill for pools, you’re leveraging technology to save time and focus on more important things in life. Liability also lies within filling your pool manually because every day pool owners overfill their pool by forgetting about the water. LevelSmart wireless auto fill water level control will allow you to automate your pool, spa, pond or water feature and reduce maintenance. When you buy a LevelSmart wireless autofill, you’re saving time, headaches, and money in the long run because you will never overfill, or burn a pump out again.  LevelSmart auto fill also is retrofittable making it the best wireless swimming pool auto fill available today. All other auto filler for pool require deck destruction which is costly.

How LevelSmart works

LevelSmart sensor wakes up every 30 minutes (48 times a day) to check your water level. If it identifies the current water level is below the set level, it will actuate the valve for seven minutes. After seven minutes of fill time, it will shut the valve off as a fail-safe but will check again 30 minutes later. This ensures you will never overfill while keeping your pool level perfect.

The advantages of having a wireless autofill pool, spa, pond or water feature system

Aside from the water supply line and the autofill spa sensor (which is mounted in the skimmer or the tile), all components of a LevelSmart autofill for spa or pool are located entirely above ground, usually at the equipment pad. Having everything visible makes troubleshooting problems or leaks far easier than it is with standard pool or spa autofill devices.  It also allows you to easily upgrade your pool and spa without deck destruction!

The importance of maintenance – proper water level in pool prevents damaging water loss

Water loss can be very damaging to your spa, pool, water feature, or pond. For one, it can ruin the balance of water chemistry, making it less clean and lowering the water quality. What’s more, it can harm the rest of your spa or pool equipment if it makes the water levels drop below the skimmer inlets, which results in air being sucked into the system and pumps being burned out.

Because water loss is so gradual, you’re unlikely to notice it in time to prevent serious damage to your pool equipment. A LevelSmart wireless pool filler automatic system prevents this problem by maintaining proper water levels at all times. Due to wireless communication, it even enables you to monitor and view analytics of your pool level and temperatures from afar, as well as receive leak alerts if your water level drops beneath a certain point with our LevelSmart Online kit!

    Easy to install. Pairing the sensor was a bit tricky (I should have read the instructions more closely). Distance from the sensor to the antenna is awesome! Once paired, the unit operated flawlessly. I replaced the included plastic valve with a brass one so that it would interface properly with my copper piping. Not a big issue at all. The water level sensor mounts easily with the included epoxy putty, even underwater. Water level has been perfect for months now. Terrific product. Highly recommended.

    I have had the pool level system installed for a month. Working great so far.
    Technical support is very good. I got a bad cable with my system (connector was slightly loose so signal was very weak). Once I ID’d problem, they promptly sent me a replacement.

    Installed level smart system. Did not have to cut a single pipe. Simply exchanged the manual valve operator with an automatic operator. Works perfectly.

    Really easy to install. It took me 2ish hours from start to finish (including installing the solenoid valve and the sensor), but most of that time was spent replacing cracked pipes from the existing pool equipment. I have had it running since June and haven’t had to make any adjustments. I would highly recommend this product!

    Purchased the LevelSmart, installation was straightforward, antenna cable just long enough to go around the double garage to where the pool equipment sits. Kit is good quality. Calibration worked as advertised, now let us see how well it keeps the pool level!
    Update: It is very hot at this time, so lots of evaporation especially as I have a water cooling fountain (must have for Houston to keep the pool refreshing): So last night, first Levelsmart filling event, level rose by 1/4 of an inch and is again exactly where I calibrated it. PERFECT. I love it.

    We bought the LevelSmart from Kona Labs after another autofill we had flooded the yard while we were on vacation. It’s been running for 2 years now and we have had no problems with it. Great purchase.

    Purchased a Kona Labs LevelSmart Autofill for our pool as we travel and in our climate, water evaporates quickly. We received it within a few days. Installation was a breeze, after we had questions concerning the antenna in conduit, then going through our alum pool enclosure to mount the antenna tip inside the enclosure. Once that was set, the LevelSmart Sensor was installed then it paired and doing what it was supposed to do. I was surprised at the ease of pairing after we had another autolevel system several years ago that was a nightmare (don’t think they are in business anymore).

    Very reliable unit, just be careful to adjust the water valve solenoid on a spa application to the correct water flow.

    Replaced an old system with LevelSmart in our community pool. We are pleased with the performance of the system and even more pleased with the performance of the sales team at Kona Labs. They responded quickly, returned my calls, and walked us through installation . Thank you Ryan….

    My wife and I purchased a home in Rancho Mirage, CA with a pool in late 2014. The pool was not originally built with an automatic pool fill system. The previous owner had installed an above deck float system that drew it’s water supply from a garden hose. Since we intended on renting the house to mostly retirement aged people during the winter season, we saw the garden hose as a trip point and knew we had to eliminate their existing system. I called a couple of pool contractors who provided me with estimates around $1,500.00 to install a mechanical float system by way of cutting a hole in our concrete pool decking. When I asked about matching the concrete texture, they said I had to contact a concrete contractor to provide the concrete finish work which I estimated would be around additional $1,000.00. I began to do more research and found Kona Labs. I was delighted to discover that the cost of the Kona Labs solution was only a fraction of the costs I’d been quoted. Because I come from an engineering background, of course, I had to go beyond just a normal installation. LOL. In addition to purchasing the level package, I also purchased a fiberglass, NEMA 4, hinged enclosure, and a stainless steel back plate to mount the power outlet, controller, and antenna on. More or less a close industrial grade installation. It has worked perfectly, and I always invite the husband of the couples we have over to show them my handy work. The level system is a cost effective solution allowing a non-intrusive installation free from the scaring of cutting a hole into your concrete pool decking.

    Our Kona Labs LevelSmart has been in place for two months and works perfectly from the first time we turned it on. The valve, base unit, and sensor were all very easy to install. We located the sensor inside the skimmer, so it is protected and out of view. An Auto fill was not part of our original pool design and would have cost hundreds if not thousands to add now. All the other auto fill devices on the market were ugly contraptions hanging on the side of the pool, rated poorly and not an option at any price. We were ecstatic when we came across the LevelSmart. Ordering and shipping happened very fast. We did have a question and the Ryan responded right away. While the device seemed expensive up front, it was a small price to pay for the convenience of not having to fool with putting water in the pool weekly and for the luxury of technology rendering the device operation invisible. FIVE STAR EVERYTHING! Thanks Ryan!
