please check the next generated csvs with ebusd 24.1 (or current source) as described there or by using a local clone of https://github.com/eBUS/ebus.github.io and using the "next" folder in there

@john30 Works for me. The old version reports

ebusd/ehp/SetMode: {
     "hcmode": {"value": 3}
}

the next has the proper value:

ebusd/ehp/SetMode: {
     "hcmode": {"value": "water"}
}
