Bluetooth communications with components inside aluminum box?

Hello - I am preparing to mount my Victron components inside a sealed aluminum box and was wondering if there was a specific antenna that would permit me to communicate with the components inside the box while it was sealed. Inside will be a SmartSolar MPPT 100/30, Orion XS 12-12V 50A, Blue Smart IP22 Charger, 500 VA Inverter VE.Direct, and outside there will be a BMV-712 Smart.

My goal is to be able to communicate with the components inside the box using an antenna to relay the information - maybe this is not possible. An alternate would be to open the top of the box on occasion to permit communication when necessary although that is not desirable.

Are you aware of a solution?

I have a small aluminium box with similar stuff in.
I didn’t have a problem, but the box also isn’t in a different compartment so i am within 4 meters.

You can add ve direct to BT dongles and mount them outside the box if you need range.

If you are going to add for each component then you may find it cheaper to add a Cerbo S in the end.
