Autofill works perfectly!
Recently installed the LevelSmart Wireless Autofill after finding no other solution that does not require running hose to pool. My pool equipment is 75' from the pool, with skimmer adjacent to stone coping and stone pavers (stone cover for skimmer lid vice plastic). I ended up mounting antenna on top of a 3' piece of 1/4" PVC tubing to keep it away from any metal. Like other online, I housed the pool equipment-side components in weather-resistant electrical housings just to keep rain elements off as much as possible. Installing the components was very simple. . . if you are comfortable doing DIY w/ PCV, installing this inline w/ pool plumbing is simple. Installing the sensor in the pool skimmer was seamless; however, you may want to measure height of your skimmer inlet prior to installation just to make sure there is enough room - especially if it's tiled. Mine is tiled and I only had 1/2" clearance on either side. Syncing sensor took 2 tries - prob because I didn't have magnet in the exact proper location.
It has been 2-3 weeks since it has been installed and no issues!! No more dragging hose to fill the pool or worrying about low pool levels when on vacation!
