Inputs also accept level sensors, flow meters, and a temperature element. The controller streams every reading into the Growlink app over Wi-Fi.

The alert log keeps the history so you can audit a tank cycle after a bad batch. Over-the-air firmware updates roll out new logic without a service call — the controller pulls them when it next phones home. Wire the BTM next to a Nutrient Doser or Precision Irrigation Controller. Refills can run on auto once levels drop below your reservoir floor.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensorex pH probe at ±0.02 pH \/ 0.01 pH resolution:\u003c\/strong\u003e Lab-grade readings on the nutrient that matters most to root uptake.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensorex EC probe:\u003c\/strong\u003e Tracks TDS through the full grow cycle so feed strength stays inside the recipe band.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs for level, flow, and temperature:\u003c\/strong\u003e Wire tank floats, flow meters, and a temp element for full reservoir telemetry on one controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWi-Fi + Growlink app:\u003c\/strong\u003e Watch tanks from the floor or off-site, then adjust strategy from a phone or laptop without driving back.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOTA firmware updates:\u003c\/strong\u003e Pulls new features and fixes over Wi-Fi — no truck roll, no USB.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive and historical alerts:\u003c\/strong\u003e Every drift event logs for review, with push notifications when a target breaks in real time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e24 VDC global power supply + mounting bracket included:\u003c\/strong\u003e Ships ready to land on a wall next to the batch tanks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
