For simple up and down - say, to set temperatures or time settings or whatever, you can of course use the existing buttons - in press to hold mode… i.e. send the same thing every time you press the buttton as against on/off… BUT for this, the buttons are WAY too big. Perhaps 4 small buttons the size of the LEDS - with a left, right, up or down arrowhead on them.,
With a smaller LCD display and 2 such buttons it would then be possible to, say, alter a temperature setting. You can of course do this with sliders but for accuracy a couple of small butttons and a display would be better.
they would also work for blinds controllers
i currently have to use this and it s big…and rather non descript…big text/icon in the middle of the button instead of pin would also help
