Wireless connectivity from your smartphone or tablet to your Apex (or other controller) is completely logical – and we embrace that. However, wireless used for the interconnecting of devices within the confines of common aquariums (that are mostly less than 6′ long) is not only unnecessary, but it reduces reliability. Our philosophy is that when distances are measured in a few feet, wireless is a solution looking for a problem. And ironically, wireless really does not save wires. You still need to use a wire to get power to the devices anyway. And let’s not forget configuration – wireless devices require syncing, endless button presses and arcane steps to get them to connect up – hopefully with you and not your neighbor. Finally for all this “benefit”, you as the consumer get the added cost of this wireless technology that must be baked into the price of every device you buy.
