well aware of the new template entity_id necessity I am a bit surprised this error is thrown:
2018-11-04 22:41:15 WARNING (MainThread) [homeassistant.components.sensor.template] Template sensor calculated_bruto_verbruik has no entity ids configured to track nor were we able to extract the entities to track from the friendly_name template(s). This entity will only be able to be updated manually.
both sensor.netto_verbruik and sensor.zp_actuele_opbrengst’ update constantly (well the sensor.zp doesn’t in the evening, since it is my solar panel sensor…), so I would have thought that to be enough for the sensor to recalculate?
— edit----
nevermind… its in the friendly_name_template…
Template sensor current_date_time has no entity ids configured to track nor were we able to extract the entities to track from the value template(s). This entity will only be able to be updated manually.
sensor.current_date_time is excluded from the recorder.
