If anyone else is being affected by the DTE energy bridge being deprecated, you can use the following configuration instead. I believe this will only work with V1 units.
sensor:
- platform: rest
name: DTE Energy Meter
resource: http://192.168.1.4/instantaneousdemand
device_class: power
state_class: measurement
unit_of_measurement: kW
value_template: '{{value[:10]}}'
availability: '{{float(value[:10]) > 0}}'
Its not hard, but it took me a few minutes to figure out, so I’m hoping it will save someone else time!
