Tom, Thanks for the pointer. I've made some progress with this but none of the search list extension examples in the Customisation guide and those I can find referenced in GoogleGroup and in other extensions seem to pass a parameter from the webpage.html.tmpl
So I have got an extension working, filling in a (hardcoded) coloured <td> cell as I wanted along with passing configuration in from skin.conf but I am unable (=don't know how) to pass the actual value down to and receive in my function. ie I can do <td class="stats_data" style="background-color: $UV_color">$current.UV</td> but am struggling on <td class="stats_data" style="background-color: $UV_color($current.UV.raw) ">$current.UV</td> any pointers appreciated, thanks On Monday, 26 June 2017 01:34:28 UTC+12, Tom Keffer wrote: > > There's an example in the Wiki > <https://github.com/weewx/weewx/wiki/Colored%20UV%20index> of how to do > this, but I don't think it's particularly efficient. > > A search list extension would probably be the most elegant.
