How to track consumption of Shelly PM and Zigbee Plugs for us in Energy Dashboard

Hi all,

I have total of 24 Sonoff TS011F Plugs and 22 Shelly with PM functionality.
This is working very well and I can see individual usage by devices in built-in Energy dashboard.

All these devices have roughly 0.5-1 W power by itself and I would like to track these values as well, since this is now its just showing as “untracked consumption”.
If possible, I would like to add this individually for each of the device and consider device status (available or not) as well.

What would be the best way to do this ?

Manually create consumption entity for each of them and update them on regular basis using an automation ?

Has anyone done something similar before ?

Thanks so much for any inputs !
