This should work for the Wallmote two button as well.
I saw in the zwave node config page that the range for the color setting is badly configured. while in the zwcfg file its a negative number for the bottom end and a positive for the high it looks like the HA interface doesn’t handle that right so the displayed low number for the accepted range is HIGHER than the High range.
in HA lovelace… “An integer between 2147483648 and 2147483647”
in the zwcfg its -2147483648 for the low and 2147483647 for the high. When it drops the negative, (treating it as an Absolute) you can’t enter squat. So i went playing around and found there are MORE COLORS YOU CAN HAVE! Not just Red/Green/Blue. I’d guess its full band color, I’ve yet to figure out the pattern as it changes when you change the byte range, so some scaling may be taking place. But here is what I’ve found…
