Hi
I want to track my electric usage and solar power in HA and I have a Kaifa MA304H4D meter with a "HAN" port.

I initially settled for a Homewizard P1 with a HAN-converter but now after a few weeks and absolutely abysmal support I cancelled the order...

So I'm back to square one again and would like some tips from you guys.

The distance between my meter and my HA server is pretty short like 3m and since I'm renovating I could place an USB or ethernet cable in the wall, is there some finished product I could use to just wire it directly?
POW-U should be compatible but quite expensive to get shipped to me

Any other options I haven't considered?

Just stick with homewizard, has been working 100% for me

I would if they would ever deliver to me but their support has been non-existing

#

I guess I could check if some local vendor carries it

Does anyone know where to find compatible HAN port devices in EU (shipped to Finland)? I just found out that there is a HAN port in my new apartment's electric meter, and I surely want to figure out some use for it. 😊
