Z-wave cached values

It appears to me that OpenZwave caches sensor values into the zwcfg_0xNNNNNN.xml-file.
This becomes a slight problem when using InfluxDB to store values and Grafana to plot them.

When Home Assistant starts, it appears it immediately reads the cached values from the file. The cached values are then sent to InfluxDB as real values would be. Since the values can be quite old, they cause problems with graphing.
Absolute values like temperature creates annoying spikes up or down in the graphs.
Accumulating values like kWh readings that are used to plot daily differences create negative values on the graph.

Is there a way to either

  1. make Home Assistant force update the cached values on each shutdown, which it doesn’t seem to do
    or
  2. make Home Assistant not to read the cached values on each startup
