Product Description
Lub 'meter' txhawb nqa STS prepaid raws tu qauv. Tokens tuaj yeem raug xa mus rau STS meter los ntawm CIU, infrared unit, lossis meter keyboard kom paub txog kev them nyiaj ua ntej, hloov valve, thiab lwm yam haujlwm. Nyob rau tib lub sijhawm, lub concentrator txhawb LORA wireless tsis siv neeg kev sib txuas lus ntawm cov meters thaum nyeem ntawv. Networking muaj nuj nqi, theem network tuaj yeem nce mus txog qib 3, uas ua rau muaj txiaj ntsig zoo heev.
Lub ntsuas dej muaj cov yam ntxwv ntawm kev them nqi raug, kev siv yooj yim, thiab kev tswj xyuas kom zoo.
