Iâm started to collect my Homevolt battery sensors from the local webserver in a package to access all data in Home-Assistant.
Please use if want, and post comments or improvements.
Invite: https://invite.tibber.com/zg5s6hew
- Enable local webserver on Homevolt
- Enabled at start or 3s press on left button under the hood
- Navigate to Homevolt local webserver by http://ip-address
- Force local webserver to enabled in Params
- Turn on password, if desired
- Turn on secure http, if desired
- Store Params to flash

Wi-Fi-guide
Om ditt batteri har dÄlig LTE-anslutning som orsakar lÄngsamma eller misslyckade uppdateringar, kan du manuellt stÀlla in Wi-Fi via batteriets portal:
Aktivera servicelÀge
- HÄll in knappen pÄ vÀnstra sidan av vÀxelriktaren i 3 sekunder.
- Anslut till batteriets Wi-Fi
- Ăppna Wi-Fi-instĂ€llningarna pĂ„ din telefon.
- Anslut till nÀtverket som heter HVSM-<QR-kod pÄ batteriet>.
- Konfigurera Wi-Fi via portalen
- NÀr du Àr ansluten bör en portal öppnas automatiskt.
- Klicka âKonfigurera Wi-Fiâ.
- VÀlj och anslut till kundens Wi-Fi-nÀtverk.
Om portalen inte öppnas automatiskt:
- Ăppna en webblĂ€sare och navigera till: http://10.133.70.1/ eller http://homevolt-.local
- Hitta serienumret pÄ vÀxelriktarens förpackning:
- Det börjar med 68b och ser ut som 68b6b34dcbac
