I suspect your issue is unrelated to the preference or undelying Z-Wave parameter, as your logs clearly indiciate that the refresh() command is being called, followed shortly by a few Z-Wave reports you'd expect to get in response to that (two of which are a MeterReport, which are things like power, voltage, etc., though I don't remember which is exactly which). That will always happen when you ask for a report, which refresh() in your driver is likely doing (it does depend on which driver you're using, but it looks a lot like Inovelli's, and that is what theirs does--and proably what most do).
So, the solution is to find out what's periodically calling refresh() on this device, then either stop that if you want to or deal with this oddity if you don't. Every 10 minutes probably isn't going to hammer your Z-Wave mesh like truly frequent reporting does, but if you don't need it, you might as well try to stop it.
