Consortium partner- DSO in energy communities and balancing group

Hello,
I’m am a founder of a italian non-profit cooperative that are making and developing Energy Communities. We are very interested to find people to deal with and grow.
We want to monitor all users and develop a web place/app that can show to our users the energy production and the energy available in the energy community.
In order to collect the energy consumption from all the users we have to install a power meter for each one.
Someone are simple energy consumers and some other are energy consumers and producers.
We saw a lot of “products ready” for openEMS. But a good compromise between functionality and quality they seemed to us: Carlo Gavazzi EM 111 meters. Why this product is not ready for OpenEMS? They use Modbus protocol as EM300. Someone of you have experience about?
It will be available soon within the “product ready”? They are already ready for openEMS? Which way to trasmit data over wifi?

Is there other meters within 60 euros that you can advice us?
