+B<EXPERIMENTAL!> The C<onewire> plugin is experimental, because it doesn't yet
+work with big setups. It works with one sensor being attached to one
+controller, but as soon as you throw in a couple more senors and maybe a hub
+or two, reading all values will take more than ten seconds (the default
+interval). We will probably add some separate thread for reading the sensors
+and some cache or something like that, but it's not done yet. We will try to
+maintain backwards compatibility in the future, but we can't probmise. So in
+short: If it works for you: Great! But kaap in mind that the config I<might>
+change, though this is unlikely. Oh, and if you want to help improving this
+plugin, just send a short notice to the mailing list. ThanksE<nbsp>:)
