Z-Wave for Commercial/Industrial Applications

I have an application to install about 60 z-wave energy meters. The only ones I found are made from Aeotec however they are not adequate for 277/480 VAC or 3 phase installations in the U.S.

I have a bunch of Eastron meters with modbus and pulse outputs installed but I can’t seem to find a z-wave pulse counter or z-wave modbus gateway.

Does anyone know of a modbus to z-wave converter? or how about a US 3 Phase 277/480 VAC z-wave energy meter?

thanks!
