I f\u00f6rra veckan hade vi en inledande workshop tillsammans Jemac Sweden AB i IoT-labbet i Kalmar. Jemac jobbar med att utveckla olika IoT-l\u00f6sningar, bl.a. har de utvecklat elm\u00e4tardongeln, en enhet som l\u00e4ser av data fr\u00e5n de nya elm\u00e4tarna. Den h\u00e4r elm\u00e4tardongeln anv\u00e4nder HAN-porten som de nya elm\u00e4tarna tillhandah\u00e5ller f\u00f6r konsumenter f\u00f6r att avl\u00e4sa och rapportera elf\u00f6rbrukning. Avl\u00e4st data ska sedan skickas cellul\u00e4rt (CAT-M1) och i och med det kommer en rad utmaningar. Den huvudsakliga utmaningen som diskuterades var utnyttjandet av den nominella str\u00f6mmen som elm\u00e4taren exponerar via HAN-porten. N\u00e4r man anv\u00e4nder str\u00f6mmen fr\u00e5n de nya elm\u00e4tarna idag s\u00e5 \u00e4r man begr\u00e4nsad till 250mA, och ibland kan enheter som str\u00f6mf\u00f6rs\u00f6rjs via HAN-porten vilja dra mer str\u00f6m \u00e4n s\u00e5, s\u00e4rskilt n\u00e4r de vill skicka med olika effekter.<\/p>\n

Projektet kommer d\u00e4rf\u00f6r att helt fokusera p\u00e5 str\u00f6mf\u00f6rbrukningens beteende i varierande milj\u00f6f\u00f6rh\u00e5llanden som kan p\u00e5verka t\u00e4ckningen. Dessutom kommer vi att sp\u00e5ra och registrera sp\u00e4nning, str\u00f6m, RSSI och eventuell signalkvalitet. Dessutom \u00f6vervakar vi n\u00e4r anslutningen f\u00f6rsvinner och f\u00f6rs\u00f6ker sp\u00e5ra grundorsaken – oavsett om det \u00e4r energibrist eller n\u00e4tverksproblem.<\/p>\n
