Greetings, new guy here but always interested in the crazy universe of modding

We just finished construction of around 25 vacation houses, all inside the same private area.
Each house has 3phase power , and we bought an atlas MK10 meter for each house (25 meters total ! )

The metering on a per-house basis is done privately. Its not done by a utility company. The utility company will only charge us for the total consumption of all 25 houses together.

Id like to do a small modification on the firmware of our MK10 to make it easier identify each house's...
