How to get the electrical power consumption of a Shelly Plug S from HA into HomeKit?

Hi there,

I switched from Homebridge to Home Assistant and now try to get my Shelly Devices controllable by HomeKit via Home Assistant.

My Shelly Motions work fine, but I am not able to get the electrical power value of my Shelly Plug S into HomeKit to use it in an existing automation there.

The basic configuration for HomeKit looks like this:

Inclusion mode is set to “include”.
So power and energy consumption are available in HA, but I do not see them in HomeKit.
On the other side, I get a lot of Buttons for each Shelly component in HomeKit.

I am sure, I have somewhere a configuration problem. Maybe somebody could give me a hint, what to check ?

Thank you in advance for your feedback!
