Aeotec Nano Switch sending 'Basic report' every 90 seconds

New to Zwave and Home Assistant. I have Aeotec USB controller and a single Aeotec Nano Switch. All is working ok. I’m noticing that every 90 seconds or so the nano switch sends a ‘Basic report’. Anyone know why it does that? I’m expecting it only to report on status changes. Snippet from log:

It’s probably reporting voltage/current/power/etc. When you did the inclusion, it should have created a number of sensor entities in addition to the switch.

If this is something you don’t want (causing network lag etc) you should be able to disable it by setting config parameters 101-103 to 0. see here (pages 12-14).

That’s what I thought at first, but those parameters are already set to 0.
