<li>polls: a comma-separated list of readings to poll. This supersedes the list of default readings to poll.</li>
<li>interfaces: supersedes the interfaces exposed by that device.</li>
<li>model: preset with device type, e.g. DS18S20.</li>
<li>resolution: resolution of temperature reading in bits, can be 9, 10, 11 or 12.
Lower resolutions allow for faster retrieval of values from the bus.
Particularly reasonable for large 1-wire installations to reduce busy times for FHEM.</li>
