The Inkbird IBS-M2 WiFi Gateway with IBS-TH3 Sensor is a gateway/sensor combo rather than a standalone controller, designed to add cloud connectivity and remote environmental sensing to existing Inkbird devices or to provide flexible probe placement for monitoring multiple aquarium locations. It holds a unique role in this set by offering a cost-effective upgrade path—cheaper than replacing a controller with built-in WiFi—and by enabling networked sensor data that complements controllers like the ITC-306A and ITC-308 for more complete aquarium temperature management.

GHL's ProfiLux 4 is best-in-class for precision and stability, offering top-tier sensor accuracy, refined PID control and professional datalogging that benefit sensitive reef setups controlling chillers over WiFi. Its German-engineered hardware and firmware focus on reliability and fine control, usually at a higher price point than Hydros or Reef Factory, but it delivers measurable technical advantages for users who prioritize exact temperature regulation and redundancy. Compared to Neptune, GHL leans more toward instrumentation-grade performance rather than broad third-party integration.
