Can anyone other than York Electric read my AMI meter?

No. The AMI com­put­er soft­ware is specif­i­cal­ly writ­ten for York Elec­tric. The sub­sta­tion’s com­mu­ni­ca­tions equip­ment is set up by the meter mod­el and ser­i­al num­ber. Each meter is added to the sys­tem by its ser­i­al num­ber and sub­sta­tion loca­tion. All oth­er infor­ma­tion and data is stored in the meter itself and is secured and sealed.
