Does S2-LP or Spirit1 have Wireless M-bus Stack support for 433MHz?

Hello,

We want to implement a Water meter using STM32 + S2-LP or STM32 + Spirit1.

We want to use Wireless M-bus protocol and we want to know if the stack is available for 433MHz?

If not is there any alternative you could suggest?

Forgot to mention that Low Power is important!

Thank you,
