Is your feature request related to a problem? Please describe.

It makes no sense to query the API as frequently for sensors such as height and weight, which are changing a lot less frequently than other sensors. This is using up unnecessary API quotas, sensor update time and to a smaller extent, CPU usage.

Describe the solution you'd like

Reduce the update interval for these sensors and/or make it confiruable, like #35

Describe alternatives you've considered
