Don’t quote multi-line templates. Only single line templates have to be quoted. Also you should supply a default value for your float filter and an availability template. So like this:
“energy_power" is provided by tasmota, I don’t think I want to patch it to change that
"energy” is essentially the namespace for a bunch of energy related MQTT topics:
sensor.tas_plug1_energy_apparentpower, sensor.tas_plug1_energy_current, sensor.tas_plug1_energy_factor, sensor.tas_plug1_energy_power, sensor.tas_plug1_energy_reactivepower, sensor.tas_plug1_energy_today, sensor.tas_plug1_energy_total, sensor.tas_plug1_energy_totalstarttime, sensor.tas_plug1_energy_voltage, sensor.tas_plug1_energy_yesterday
