I can give you a partial answer: I'm also working on the SERCOMM NA502 
and NA502s that are also sold as Vera Secure, Smart Home by Hornbach, A1 
Smart Home Gateway and a few other brands (I have the A1 branded 
version). Basically, I've got ZWave running, you can track the status 
here: https://forum.openwrt.org/t/adding-support-for-sercomms-na502/22495

Regarding the Vera Lite, I'm still investigating the possibilities and 
have not yet booted any custom firmware. I don't see a reason why the 
ZWave controller shouldn't be visible (it's attached to a UART). 
However, I found only limited information in whether this particular 
controller is supported by OpenZWave or Z-Wave JS.

My ultimate goal with both SERCOMM devices is getting ZWaveJS2MQTT 
running so that a home automation software can talk to the gateway.
