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

Have you noticed how the water level in your pool, spa, pond, or water feature falls over time? This can happen due to natural occurrences (evaporation, wind, water splashing out of the pool, etc.), but it can also be the result of a leak or subpar construction. Pool owners of yesteryear had to manually check the water levels of their pools, but today, LevelSmart wireless auto-fill systems provide an easier and more efficient way to do this.

An automatic pool fill system (also called a water level controller) is a device that monitors water levels in your spa or pool, and automatically regulates them by optimizing system performance and managing water flow. LevelSmart automatic spa fill system improves the autofill technology by adding wireless ease-of-use to the four main advantages an automatic fill for pools and spas already offers.

What can a LevelSmart wireless pool auto fill do for you

The first advantage of using a spa or pool auto fill lies in power conservation. By controlling the water levels automatically, the smart meter wireless water fill system limits electricity usage. Therefore, by using an autofill for pools, you’re wasting a lot less power and water than you would if you were doing it manually. Such energy conservation is not only beneficial to the planet as a whole, it also means a wireless auto fill water level control will decrease your electricity and water bills. In other words, by investing in a LevelSmart wireless autofill, you’re saving money in the long run.

Another critical benefit of having an autofill for spa or pool is that it’s automatic. You don’t have to remember to manually check the water levels because the Level Smart auto fill is already programmed to do that. Finally, an auto filler for pool or spa maximizes water usage. For instance, water pumps are used more often during midday than during the night. A wireless swimming pool auto fill automatically adds more water during midday and less at night, so the water remains at correct levels 24/7.

The advantages of 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.

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.

    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….
