# Resol KM1/KM2, DL2/DL2Plus/DL3, VBus/LAN, VBus/USB

> Resol KM1/KM2, DL2/DL2Plus/DL3, VBus/LAN, VBus/USB is a Marketplace integration for Home Assistant. It has 235 installs sharing analytics, works locally and was last updated October 14, 2026.

Resol KM1/KM2, DL2/DL2Plus/DL3, VBus/LAN, VBus/USB is an integration that reads sensor data from Resol solar and heating controller devices. It talks to the device locally through its web service and detects whether a KM2 or a DL2/DL2Plus/DL3 is in use. KM1, VBus/LAN and VBus/USB work by pointing it at a json-live-data-server instead. Every bus device connected to the Resol unit appears as its own device in Home Assistant, with its sensors grouped under it. Sensors without a unit are created as diagnostic sensors and stay disabled until enabled by hand. Setup runs in the UI and asks for host, port, login details, an update interval and, on DL2/DL3 devices, an optional filter ID.
