Om du vill ha en billig och robust l\u00f6sning f\u00f6r att f\u00e5 in m\u00e4tv\u00e4rden fr\u00e5n din elm\u00e4tare i Home Assistant och har m\u00f6jlighet att ha en Home Assistant Green i samma utrymme som elm\u00e4taren, kan en USB adapter vara l\u00e4mplig. Det \u00e4r aningen kr\u00e5ngligare att f\u00e5 detta att fungera j\u00e4mf\u00f6rt med en av v\u00e5ra elm\u00e4taravl\u00e4sare som kommunicerar via MQTT men f\u00f6rdelarna \u00e4r en fast, p\u00e5litlig anslutning med billigare utrustning. Denna guide \u00e4r till\u00e4mpbar p\u00e5 alla v\u00e5ra USB adaptrar, oavsett om du har en elm\u00e4tare med RJ12 eller RJ45 port. Vissa skillnader kan f\u00f6rekomma men dessa tas upp i de steg de \u00e4r aktuella.<\/p>\n\n\n\n

Steg 1: Installera Home Assistant Green<\/h2>\n\n\n\n

Installera din Home Assistant Green enligt de medf\u00f6ljande instruktionerna<\/a>. Och skapa ett anv\u00e4ndarkonto i appen eller via webbl\u00e4saren. <\/p>\n\n\n\n

T\u00e4nk p\u00e5 att installera h\u00e5rdvaran tillr\u00e4ckligt n\u00e4ra elm\u00e4taren s\u00e5 att den kan n\u00e5s med kablarna. Se maximala kabell\u00e4ngder i n\u00e4sta steg.<\/p>\n\n\n\n

Steg 2: Anslut elm\u00e4taren till Home Assistant<\/h2>\n\n\n\n

Anslut RJ12\/RJ45 kabeln till elm\u00e4atrens P1\/HAN port och andra \u00e4ndan i USB adaptern. Anslut sedan USB kabeln mellan USB adaptern och en av USB portarna p\u00e5 Home Assistant Green.<\/p>\n\n\n\n

Vi rekommenderar att du inte anv\u00e4nder kablar som \u00e4r l\u00e4ngre \u00e4n dessa rekomenderade l\u00e4ngder:<\/p>\n\n\n\n

Kabeltyp<\/strong><\/td>Maxl\u00e4ngd<\/strong><\/td><\/tr>
RJ12<\/td>0,6m<\/td><\/tr>
RJ45<\/td>100m<\/td><\/tr>
USB<\/td>3m<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Steg 4: Installera till\u00e4gg f\u00f6r webbterminal<\/h2>\n\n\n\n

Logga in i Home Assistants webbgr\u00e4nssnitt via en webbl\u00e4sare genom att surfa in p\u00e5 http:\/\/<lokal-ip-address>:8123<\/em>. Klicka sedan p\u00e5 ”Inst\u00e4llningar \uffeb Till\u00e4gg”.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Klicka sedan p\u00e5 ”Till\u00e4ggsbutik”, s\u00f6k efter ”Terminal” och v\u00e4lj ”Advanced SSH & Web Terminal”.<\/p>\n\n\n\n

\n
\"\"<\/figure>\n<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Klicka sedan p\u00e5 ”Installera” och v\u00e4nta n\u00e5gra sekunder tills till\u00e4gget har installerats.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\u00c4ven om vi inte kommer att anv\u00e4nda SSH i denna guide s\u00e5 m\u00e5ste ett SSH-l\u00f6senord s\u00e4ttas f\u00f6r att till\u00e4gget ska kunna starta. Det g\u00f6r man genom att g\u00e5 till fliken ”Konfiguration” och skriva ett l\u00f6senord i SSH-konfigurationen efter ”password:”.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Nu n\u00e4r ett s\u00e4kert l\u00f6senord har konfigurerats, g\u00e5r man tillbaka till fliken ”Info” och sl\u00e5r p\u00e5 inst\u00e4llningen ”Visa i sidof\u00e4lt”. Sedan klickar man p\u00e5 ”Starta” f\u00f6r att starta till\u00e4gget.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Steg 5: Installera AMS HAN integration<\/h2>\n\n\n\n

Vi kommer att anv\u00e4nda integrationen AMS HAN<\/a> f\u00f6r att l\u00e4sa och tolka m\u00e4tv\u00e4rden via USB. Denna integration beh\u00f6ver vi l\u00e4gga till manuellt via terminalen.<\/p>\n\n\n\n

Klicka p\u00e5 ”Terminal” i sido menyn och skriv f\u00f6ljande kommandon:<\/p>\n\n\n\n

mkdir -p config\/custom_components\nwget https:\/\/github.com\/toreamun\/amshan-homeassistant\/releases\/latest\/download\/amshan.zip\nunzip amshan.zip -d config\/custom_components\/amshan\nrm amshan.zip\nreboot<\/pre>\n\n\n\n
Din Home Assistant Green kommer att starta om efter att det sista kommandot har k\u00f6rts och det kan ta en liten stund innan det g\u00e5r att ansluta till den igen. <\/p>\n\n\n\n
Steg 6: L\u00e4gg till integrationen<\/h2>\n\n\n\n
Nu kan du navigera till \u201dInst\u00e4llningar \uffeb Enheter och tj\u00e4nster\u201d.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Sedan klickar du p\u00e5 ”L\u00e4gg till integration” och s\u00f6ker efter ”amshan” f\u00f6r att hitta integrationen. Om den inte dyker upp kan du beh\u00f6va rensa webbl\u00e4sarens cacheminne.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Klicka p\u00e5 integrationen och v\u00e4lj ”serial” som anslutningstyp. D\u00e4refter dyker det upp inst\u00e4llningar f\u00f6r seriell kommunikation med elm\u00e4taren. De f\u00f6rinst\u00e4llda inst\u00e4llningarna fungerar om du har en m\u00e4tare med norsk HAN standard (med RJ45 port). tabellen nedan visar vilka inst\u00e4llningar du kan beh\u00f6va anpassa efter din m\u00e4tare:<\/p>\n\n\n\n
Inst\u00e4llning<\/strong><\/td>M\u00e4tare fr\u00e5n Aidon med RJ45 port<\/strong><\/td>\u00d6vriga m\u00e4tare med RJ45 port<\/strong><\/td>M\u00e4tare med RJ12 port<\/strong><\/td><\/td><\/td><\/tr>
Baud rate<\/td>2400<\/td>2400<\/td>115200<\/td><\/td><\/td><\/tr>
Parity checking<\/td>E<\/td>N<\/td>N<\/td><\/td><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n
N\u00e4r du spara inst\u00e4llningarna kommer integrationen v\u00e4nta en stund tills den f\u00e5r ett datapaket fr\u00e5n m\u00e4taren. Om allt g\u00e5r som det ska, l\u00e4ggs integrationen till och en enhet kommer skapas f\u00f6r m\u00e4taren samt entiteter f\u00f6r varje m\u00e4tv\u00e4rde som g\u00e5r att l\u00e4sa fr\u00e5n m\u00e4taren.<\/p>\n","protected":false},"excerpt":{"rendered":"
