Hey guys,
I know my integration is quite old. It started back in 2021. But recently we completely rewrote the integration and brought it to the new UI Configuration packed with a lot of other features.
Please find the details about it here: GitHub - dm82m/hass-Deltasol-KM2: Custom component for retrieving sensor information from Resol KM1/KM2, DL2/DL3, VBus/LAN, VBus/USB
If you have questions or find bugs, you can open issues in Github or ask here.
Best,
Dirk
