You will need to contact DTE and tell them you’d like your Energy Bridge to bind to a different meter. AFAIK, you can’t have it bound to two meters (that would be very nice if it was possible!)
See the Troubleshooting section of the Insight page for the email/phone to reach somebody that knows about the Energy Bridge and can probably help. (If you find out it’s possible to bind the EB to multiple meters, let us know!)
On an unrelated note: I worked with the HA devs, and the latest release will iron out the issues with using the “minutely summation” data with the Energy dashboard without any extra “sensors”. Usage and cost are now being calculated correctly for me with this config:
sensor:
- platform: mqtt
name: "Household Electricity Usage"
icon: mdi:transmission-tower
state_topic: "event/metering/summation/minute"
unit_of_measurement: 'kWh'
# the Energy Bridge returns "Watt-minutes" every minute in the "value"; convert it to kilowatt-hours
value_template: "{{ value_json.value | float / 60000 }}"
# the "time" in the message is a Unix-like timestamp (in milliseconds) of the start of the last reading
last_reset_value_template: "{{ now().fromtimestamp(value_json.time / 1000).replace(tzinfo=now().tzinfo) }}"
device_class: energy
state_class: total
