Read full descriptionHide full description
The Aquatopper is the ultimate product to ensure your water level in your swimming pool is always maintained at the correct level. The product is app driven given you full control and notifications when the system is topping up. There are 3 components that make up the system: 1. LEVEL SENSOR The level sensor is located in the skimmer of your pool. A bracket is supplied that you house the sensor in on the bottom of the skimmer basket. This level sensor is battery operated with a 5 year lifetime guarantee 2. TAP VALVE The tap valve is connected to your garden tap. Using the push fit connections you then connected your hosepipe to the valve and run this to the edge of your swimming pool. This tap valve is also battery operated with a 5 year lifetime guarantee 3. LORA GATEWAY The gateway is attached to your home wifi and communicates with the level sensor and the tap valve. Using the latest wireless technology ( LoRA ) which is a long range, low power wireless platform means that the expected life of the built in battery is 5 years. This means that your pool does not need to be within your wifi radius to work. When the level of the pool drops to the customised level, the sensor sends a signal via the gateway to the tap valve to open. When the level raises to the required level again a signal is sent to switch off the hose. Simple as thatβ¦.but with some very impressive technology behind it!

Verdict
The clearest difference is ads: Aquatopper at none against +Compass+'s shown. Aquatopper also leads on update cadence (every 10 days vs monthly). +Compass+'s advantage is iOS requirement (13.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.
