Thanks for the HomeSeer suggestion @Jeff Rose. Regrettably, Universal Devices does not have the Polisy or Polisy Pro available (supply chain issues) and it’s possible that it might not return (Universal Devices is apparently working on an “Eisy” replacement that wouldn’t have internal Z-Wave/Zibee module).
Went with the HomeTroller Pi as it has the 700 Series Z-Wave controller including S2 security built-in and allows frequency selection so it’s international supported. Using the UltraM1G3 plugin (currently an HS3 plugin, hopefully will be updated for HS4 at some point).
