Had a few failed z-wave devices, replacement no longer compatible with Old Legacy Vera Plus controller.
I have therefore taken the plunge and decided to move all into Node-red amd Zwave-js.
I hear there will be a breaking update to Zwave-js node (V11) so until then i am just going to patch the broken devices into the old Legacy systems, until V11 is released.
On advice from @marcus-j-davies I purchased a ZWA-2 Z-wave antenna. Home Assistant Connect ZWA-2 - The Pi Hut. Home assistant is not required
I have Node-red running on a routed android box and to connect the antenna i had to give /dev/ttyACM0 permissions 777 using the termux boot directory, info here Android - termux - Playstore no longer a recommended install source - #5 by btsimonh
Using
#!/data/data/com.termux/files/usr/bin/sh
sudo chmod 777 "/dev/ttyACM0"
A BIg thank you to @marcus-j-davies and the Z-Wave-js team Z-Wave JS - Z-Wave driver written entirely in JavaScript/TypeScript. And i should thank @btsimonh also
