I have a raspberry with Home Assistant Tracking energy usage using the Aeotec Home Energy METER Gen5 (ZWave) and a WiFi Shelly 3EM (2 separate locations).
I was in need to track the consumed energy in \u20ac, home assistant allows you to pick a “Use an entity with current price” in the energy dashboard<\/p>\n\n\n

I did not want to deal with automation and such, so I devised a simple template sensor that switches its “price” between specific time periods. (pro tip: convert the current hour of the day to minutes + add the current minutes)<\/p>\n\n\n\n

here we see the sensor switching price<\/p>\n\n\n

The new modern way of doing this would be with a template sensor<\/p>\n\n\n\n

Based on EDF’s peak and off-peak hours<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n
template:\n    - sensor:\n        - name: \"EDF Price\"\n          unique_id: edf_price\n          unit_of_measurement: EUR\/kWh\n          state:  \"\n            {% set time = now().hour * 60 + now().minute %}\n            {% if time > 750 and time < 870 or time > 90 and time < 450 %}\n            {{'14.70'|float\/100}}\n            {% else %}\n            {{'18.41'|float\/100}}\n            {% endif %}\n            \" <\/pre>\n\n\n\n
Depending on your peak hours they could be different:<\/p>\n\n\n

A variant on the same template sensor<\/p>\n\n\n\n
template:\n    - sensor:\n        - name: \"EDF Price\"\n          unique_id: edf_price\n          unit_of_measurement: EUR\/kWh\n          state:  \"\n            {% set time = now().hour * 60 + now().minute %}\n            {% set startTime = 21 * 60 + 56 %}\n            {% set endTime = 5 * 60 + 56 %}\n            {% if time >= startTime or time <= endTime %}\n            {{'14.70'|float\/100}}\n            {% else %}\n            {{'18.41'|float\/100}}\n            {% endif %}\n            \" <\/pre>\n\n\n

The legacy way of doing it (don’t do this!)<\/h2>\n\n\n\n
The old way would have been adding a template under the sensor <\/a><\/p>\n\n\n\n
