[Not issue] Question on HW implementation

[mikkel75]

Hi,

Anybody have links to HW implementation on HAN module format? I see there are forks of this code that implements HW with super cap (5F), but is there a HAN format module available somewhere?

Thanks!

You talking about a hardware module that physically fits into the Han slot with built-in power buffer? Not to my knowledge, but it certainly would be nice.

@mikkel75 are you thinking a diy module like this powered directly from the power meter? https://www.smartred-shop.de/en/p/smart-me-kamstrup-modul-for-omnipower?fbclid=IwAR3FgYR6YI2KpMQZY9paML6Hx2Mqv0e1Is_jGWqKUWMdXAKYsp03c7XqzbI

My meter is placed outside, so I am also thinking to continue Morten’s work on local power with super cap. I also have 3D printer and would like to have et placed in a nice module. Any help on the electronics/project is welcome

I think his intention was to grasp the process of connecting the hardware to the port on the omnipower. In most other setups utilizing the Han-port/P1, there's typically a pull-up resistor and a voltage conversion from 5V to 3.3V. Additionally, the super-cap is present because the current at 75mA isn't sufficient to operate both the controller and the Wi-Fi simultaneously. He overlooked the fact that the omnipower port doesn't require a pull-up, and "Claustn" utilized an external power source (5V x Amps). If not paying attantion this is very har do miss in the description :)
