Second last value from database

[Mikael Fredriksson]

Hi.

Can't figure it out!

How can I get the second last, third last and so on from my weewx.sdb?

<td>$year.avg_distance.last</td>

This gives me the last value.

Thanks, Micael

Unfortunately, there is no aggregation type of "next to last," etc. Only last.

You would have to write your own search list extension.

Ok, then I'll skip this for now as I'm not able to write that on my own.
Thanks for your answer Thomas.
