Z-Wave get commands (for example get meter)


I installed oppen Z-wave and I can receive data from my multiswitch which also meassures Voltage, Power etc. In order to get this information on demand, I have to send a get meter command. For example:
Meter Get Command: [Command Class Meter, Meter Get, Scale =0x02(W)]
How would this command be put into Node Red and where can I find more information about other open z-wave get commands?
Any help appreciated.
