Measuring dumb spotlights

[Chaoscontrol]

New user here. I have several dumb spotlights around the house that I would like measured. This is more of a wiring/electrical question.

Some are attached to smart dimmer, and some to smart switches. I understand the proper way would be to measure the combination, so it includes the switch/dimmer energy. But I'm not really that interested, since that will be very small, compared to the light energy. And I really would like to avoid opening my switches (some gave me trouble when I installed them).

Is it possible for me to measure a single one of the spotlights using a Shelly PM Mini Gen3? How would I have to connect it?

It's way easier for me to take out a single spotlight than it is the smart switches. Then with a single spotlight measurement, I can extrapolate for each room as they're all the same.

I understand I'll be missing switches and dimmer energy, but I'm ok with that.

Thanks!!

Yes shelly PM mini gen3 would be perfectly suitable.

Here is the wiring schema:

You connect it in series, either before the smart switch / dimmer or after.

When you connect it before the smart switch you live wire (brown) in the L on the PM mini,
and the O goes to the dimmer where the brown wire is now. Run a short new wire there.

When you want to only measure the bulb you connect it in series after the smart switch. So between the switch and the light.
In that case it's probably a black wire (in Netherlands it is) and you connect that to O on the PM mini (that goes to the light).
Where the black wire is currently in the dimmer you run a new cable connecting to L on the PM mini.
