If you're planning on using a Z-stick to include this switch without security (highly recommended!!), the install process for the Silicon labs tools (which you'll need to include the device without SO security) is different for the latest download (as of February 2023).
Use this first to get the z-stick up and running on your PC. I ordered the Zooz version from amazon.ca
Then look at this PDF to learn how to include/exclude devices without security in HE. It looks at first glance to be related to removing ghost devices, but it also includes instructions on how to include a device without security on page 8. You'll need this pdf to figure out how to get the z-wave stick set up for inclusion etc.
I'm happy to report that the switch now works correctly for the first time in over a year since installing it in HE (where SO security was forced). Using this driver AND having the 240V switch joined to the HE hub without security using a Z-stick zWave controller did the trick. It now reports power more or less instantly from the induction cooktop connected to it, and reliably controls the kitchen exhaust fan. It's also no longer on the top of the list for device stats in the logs.
It was a bit of a slog to install the z-wave stick PC tools (see my comments above), and I did have to factory reset the device and include/exclude a few times. That said, having the 240 volt power reported reliably (without constant polling/refresh via an automation) was important as I wanted the kitchen exhaust to work reliably, as well as the home HRV system which is also cranked to full speed (via HE and 0-10 volt fan control) when the kitchen induction range is in use.
