Errors in System in built system driver for Aeotec Dual Nano Switch

[nrm94ee330]

I just realized that I am getting these errors in the System driver for the aeotec dual nano driver..
further, the child devices dont update the on/off status when toggled.. I have to refresh them, and then they show the state.

What hub hardware model and platform version are you running? And did you switch to Z-Wave JS or are you running default/"legacy" Z-Wave?

There are some fixes for Meter Reports in 2.4.2, currently in beta, though I don't know if it will fix your exact issue. You can join now if you want or wait for release -- no timeline, as usual.

The other issue appears to involve a user driver. Maybe there's just not an off() command in the code for some reason?

[nrm94ee330]

Sure, how do I sign up for the beta version?

.. in the meanwhile.. I installed the custom driver from here by dmitry.rozovik

[RELEASE] Aeotec Smart Switch Driver 7 EU version

As the US version of the driver did not work at all, and the v6 driver does not truly match either I wrote this driver. Works with and without security. You can find the source here: https://github.com/reneboer/Hubitat/tree/main/Aeotec This driver is available via HPM. Search by Aeotec Smart. Cheers Rene

and everything is working, without any errors, and it also enabled the energy monitoring.. that is missing from the inbuilt driver.

You can join the beta with these steps:

Join our Beta Program!

We have released a new beta version. If you are looking to try future updates before they are released publicly, we are looking for a few more users to join our program. If you are interested, please request to join our Beta Testers group. [image] As one of our beta testers, you get a chance to interact with Hubitat engineers, and to try out new integrations, services, and platform enhancements, before they are released to the public. Please note, that if selected and your hub is enrolled to…

However, I'd guess it's likely to be released fairly soon if you aren't otherwise interested in testing, so just waiting a bit more should work, too.

For now, however, you might also want to keep the custom driver. It doesn't look like the built-in one parses power events, though the command class appears to be there for all the fingerprints the driver was written to support, so if the device doesn't do anything weird, it should be fairly easy to add (just probably not in 2.4.2).
