IoT Wifi Edge Device (Node) for Water Filter Monitor

Looking for Developer who can fabricate POC IoT boards for feasibility study. I currently have Particle Photon boards coded for connection of digital pulse, flow sensors. I am considering the Silicon Labs RS9116 Wifi Chip Set as GoTo item. I am using MyDevices for backend Dashboard and analytics. In addition, to a single flow sensor (digital pulse), there are newly developed 3 in 1 Flow sensors that incorporate a.) Flow, b.) Conductivity c.) Temperature. Part of my PRD would enable flexibility to connect either a single 3-wire flow sensor, or a 5- wire 3-1 sensor, (Such as Digmesa products). The Conductivity and Temp are Analog. This is a product which would ideally be battery powered, with minimal data daily upload. As most water filters are undersink, where connectivity, signal strength and battery management are essential considerations. Thank You. Dave Familiar with Thread or Matter?
